Inverse swarm monsters

I think this dude was an inverse swarm
Image source: Final Fantasy 7

In a swarm monster, multiple enemies are represented as a single monster mechanically. This is practical because it is easier to manage for the referee and also interesting on the player interface side because a swarm of flying demonic bells might be immune to most weapons but vulnerable to area effects and perhaps sweet singing. (I believe 3E should get credit for this innovation, though I am not sure about that.)

In a recent post, Gus catalogued a number of ways to make solo beasts more interesting and challenging. To this toolbox, I would add the inverse swarm, which is a single enemy represented mechanically by multiple monsters.

So an elder dragon might have head, body, two claws, wings, and a tail, each with a separate attack, different ACs, and its own HP total. This avoids the biggest weakness of beasts versus adventuring parties, which is the limited number of actions the monster can take (1, or maybe 3 for a claw claw bite routine) compared to the 6+ chances an adventuring party gets to take on the attack roulette wheel each round. It also allows interesting strategies, like disabling particular abilities.

The only real downside is that the referee needs to spend some thought on the monster, preferably beforehand (though it is possible to improvise a less complicated inverse swarm).

Helheim class and review

2 Replies

It is hard to say too much about Helheim without spoiling the story, so I will keep this brief. First, I liked it. It is a relatively self-contained story with an engaging, vaguely Norse setting that focuses on an undead warrior and some witches. (What more could you want?) The art is a bit photoshop for my taste (flat in both color and line), but it gets the story across just fine and has some creative character visuals. The setup would work nicely for a small faction-based overland adventure. The depiction of the supernatural is good too; recognizable but not cliche. Overall, recommended.

You can get it at Comixology, and notably the publisher has enabled DRM-free access to PDF and CBZ formats. Just checking that, it looks like there is a followup series, Brides of Helheim, but the collected edition is not out yet and I have not read it. Helheim is by Cullen Bunn and Joëlle Jones. You can find more info about Cullen Bunn at his site. He’s also behind The Sixth Gun.

Here is a PDF version of the class detailed below.

Helheim class

HD, attack, save, and XP as fighter
Benefits: toughness (damage reduction), body augmentation, undeath
Drawbacks: recovery and charisma loss, stench, no missile weapons

A helheim is a zombie raised from the body of a hero or person with otherwise exceptional will. Such zombies are often employed by witches as enforcers of curses or avengers. Sometimes, the witch’s necromancy is not sufficient to fully dominate the creature, however, and the helheim becomes free.

Toughness: Helheims ignore 3 points of damage from mundane weapons, including claws and teeth. Each time a helheim suffers damage, they lose one point of charisma permanently. These points never return, and represent the descent of the helheim into a mass of patchwork, stitched flesh.

Augmentation: As helheims grow in power, they may incorporate body parts from defeated foes. For each experience level, a helheim can incorporate one special body part. Such parts may be added or replaced during downtime with surgery, but only from fresh bodies slain by the helheim’s own hand in combat. The remains of an execution will not do, being tainted by passivity and oppression, the qualities most inimical to a zombie-creature’s autonomy. Incorporated parts may grant additional capabilities. For example, a harpy’s wings might grant awkward flight. Actual abilities may be less literal, however, as negotiated between player and referee. Any powers granted should be determined with an eye toward maintaining future challenge within the game.

Undeath: Helheims do not need to eat or breathe, but they must periodically fall into reverie, much like sleep, to retain their humanity. Otherwise, the helheim will slip back into a partially catatonic state waiting for necromantic commands.

Recovery: Helheims do not recover as normal. Instead, damaged limbs or body parts must be physically stitched back together or replaced. Any necromancer or mundane surgeon can accomplish this task, but a helheim may not repair themselves without assistance.

Stench: The stink of the grave is never entirely absent from a helheim, as the zombie body is continually rotting from the flux of necromantic energy. This stench makes it impossible for a helheim to surprise enemies with a sense of smell unless chaotic circumstances would make such senses useless.

Weapons: For all their great strength, a helheim’s motor control and visual acuity are crude. Though they can use thrown weapons such as daggers and small axes, they cannot effectively use missile weapons. Beyond several hundred feet their undead eyes perceive only a phantasmagoric riot of swampy color.

The helheim class is suitable either for new first level characters or as an option for deceased player characters raised from the dead.

Deflective shields

6 Replies

My first Dark Souls dude, with a shield

These are the current shield rules (approximately the third revision) for The Final Castle. To make sense, I have included preliminarily a few general combat rules as well. Combat Tests are d20, roll high, aiming to meet or exceed an enemy threat level (similar to the probably familiar armor class or difficulty class). Hopefully the fragmentary nature is not too hard to understand.

“Unbalanced” is a state, something like a temporary condition (in 3E terms) that persists until addressed by the combatant. Deflection is a reaction that can be taken in response to an enemy attack.

Overkill

Exceeding the target number of an Ability Test by at least 4 or rolling a 20 prior to any modifiers is an Overkill. For Combat Tests, Overkill adds 1d6 damage and may have additional effects in other contexts.

Unbalanced

Unbalanced combatants may only Melee, Shoot, Flee, or Recover and may not deflect attacks withs Shields. Recover balance with a maneuver.

Deflection

To deflect an attack, deploy a shield. Deflection must be declared before rolling dice to resolve an attack. Deploying a shield Unbalances a combatant but does not require an Action. Shields may not be deployed when Unbalanced. Bypass Maneuvers cannot be deflected with a shield. Different kinds of shields offer other benefits. See the Shields entry in the Weapons section for details.

Maneuvers

Resolve Maneuvers with Melee, Shoot, or Throw Actions depending on the character of the desired effect, substituting Maneuver effects for damage. Overkill applies to Maneuvers also. Thus, Maneuver Overkills cause the Maneuver effect and also 1d6 damage.

Recover (Maneuver)

Recover from being Unbalanced, stand up from prone, or escape a Grapple.

Shields

Bucklers grant +4 to parry maneuvers, but are useless against ranged attacks and great weapons.
Medium shields grant +2 defense against small missiles.
Tower shields deflect all small missiles but are useless against standard or smaller weapons.

Putting this all together, it means that PCs with a shield can deflect (that is, totally nullify) one melee attack per combat (not per round) essentially for free, though the deflection must be “used” before rolling Defense (the equivalent in the system of an enemy attack roll). After a shield has been used for deflection, combat options narrow generally due to becoming Unbalanced, and specifically the shield may not be used again until balance is recovered.

Since maneuvers work like attack rolls, but substituting effects for standard damage and only inflicting any damage upon Overkill results (exceeding target numbers by 4 or rolling a natural 20), the effect is that a skilled fighter attempting a Recovery Maneuver is still fighting (not potentially “wasting” a turn), just at a disadvantage (approximately -4) if they wish to earn another use of their shield during the current combat.

(Don’t worry about Parry Maneuvers; they are beyond the scope of this post.)

Training bonuses

3 Replies

Dark Souls swords by Bringess

This is an idea for weapon training that I had which is probably too fiddly for online play, but might work in person. To gain more than a +1 to attack or damage (whether from attack bonus, strength, or wherever bonuses come from in your system of choice), a combatant must train with a given weapon. Each weapon is rated with minimum stat requirements and maximum bonus potential. Mundane weapons might be, for example, min +0 and max +3/+3, meaning that anyone without a penalty can use them and they can support at most a +3 to attack and damage. Insisting on using a weapon without the minimum stat imposes some large penalty (-4 or 5E style disadvantage).

The constraints would need to be tracked for each weapon along with training level, which could default to starting scores for starting weapons initially (representing background training). For example, consider a first level Labyrinth Lord fighter with 16 strength, which grants a +2 to attack and damage. A first level fighter in this system also has the equivalent of a +1 bonus to attack. Assume further that this character starts with a battle axe and dagger. Under skills, the player would write battle axe +3/+2 and dagger +3/+2. This is the character’s initial training. If a sword is picked up, it will be wielded with +0/+0 until the character can train with it.

How does training work? As a downtime action, the character can pay for training in a weapon. This costs some set amount, maybe based on bonus to be unlocked, say 500 GP per target plus (so, moving from +1 to +2 would cost 1000 GP). This raises either the attack or the damage by one point, assuming that is supported by class attack bonus or ability scores. Thus, that example first level character above can gain no more bonus points in battle axe until ability scores or attack bonus increase.

The benefits are that it gives fighters something to do during downtime actions, somewhat restrains bonus progression, makes special weapons more valuable without needing to resort to magic weapons as treasure all the time, and allows fighters to ease in to using crazy weapons like the Berserk dragon slayer sword or the asylum demon’s great hammer which might make their use feel a bit more special (and also more fictionally justified). It would also allow weapons to be numerically defined on dimensions of finesse and brutality. For example, a big club might be +1/+4 in potential, making it a good choice for a character with low skill but high strength (assuming such is possible in the base system).

This would would particularly well with a system that has regular stat increases, such as this adventurer class or Green Ronin’s Dragon Age, but should also be functional with a regular attack bonus.

Pits & Perils divergences

5 Replies

Because I am tentatively planning to run a Google Plus hangout game of Pits & Perils this friday, I was reviewing the rules. While doing this, it occurred to me that it might be useful to summarize the aspects that differ from “how things are usually done.”

As a player familiar with traditional fantasy roleplaying games but new to Pits & Perils, I think these are the most obvious differences.

PCs have 1 or 2 abilities. As in, you “have strength” (no numbers).
Abilities constrain what you can do.
To attack, roll 2d6. 9-11 = 1 damage. 12 = 2 damage.
Fighters get +1 to attack. Magic weapons grant bonuses here also.
Saving throws succeed on 7+ rolling 2d6.
Using an ability (for example, dexterity) works like a saving throw.
Encumbrance is armor & shield + 10 more items (hard limit).
HP is static (for example, a 3rd level fighter has 14 HP).
Armor works by adding a small amount of HP.
Casting a spell costs one spell point (no preparation).

There are a number of other specific rules, but if you already know, for example, B/X D&D, I think this will get you most of the way there.

Dispell as counter-spell

13 Replies

To counter a spell, expend one prepared spell and follow the formula presented for dispell magic:

Dispell Magic: Unless countered, this spell will be effective in dispelling enchantments of most kinds (referee’s option), except those on magical items and the like. This is modified by the following formula. The success of a Dispell Magic spell is a ratio of the dispeller over the original spell caster, so if a 5th level Magic-User attempts to dispell the spell of a 10th level Magic-User there is a 50% chance of success. Duration: 1 turn. Range: 12″.

Source: Men & Magic, page 25.

That is, any prepared spell can be “converted” into an antagonistic dispell magic. One could without issue probably extend that to full dispell magic functionality (thereby doing away with the need to find, learn, or prepare dispell magic as a distinct spell), given that removing enchantments is a relatively core aspect of wizarding, though I could understand wanting to keep the full dispell magic a separate thing.

Note that OD&D does this differently than AD&D, which works like the BRP resistance table (50% success modified by level differential). To make the difference clear, in OD&D a 9th level magic-user has a 90% chance of successfully dispelling an 10th level magic-user’s enchantment (9/10), while in AD&D the chance would be only 45% (50% -5% for having one less level).

Alternatively, compare spell levels rather than class levels using the OD&D formula. So, expending a second level spell in an attempt to counter a third level spell would have a 2/3 (66%) chance of success. This method might be preferred if you see the countering process as an opposition of specific spell energies rather than a contest between the overall skill of the two magic-users.

The burn spells paradigm is becoming increasingly attractive to me. There is some danger of complexity creep, so the possibilities should be limited to a small number of effects. That said, having several default options frees up magic-users to prepare more obscure or interesting spells, which otherwise might not get as much use, much as 3E clerics were able to convert any spells into cures. Further, requiring the expenditure of prepared spells to power such effects retains some degree of resource constraint, unlike make other unlimited or at-will approaches, and doesn’t require tracking any additional information, since spell slots are already managed.

The options so far that I have thought about are maleficence, magical defense, and now dispell magic. I could see adding read magic to that list perhaps, though I am also experimenting with replacing read magic with a “skill” type d6 roll that comes at the cost of an exploration turn.

(This idea came to me when I repurposed dispell magic for banishing summoned creatures.)

OD&D summoning

3 Replies

Mateo had the (brilliant) idea to use the retainer and morale system as the base for a summoner class. His approach adjusts the loyalty rolls based on summoner level, monster HD, and other factors. This allows higher level summoners to control more powerful creatures (on average).

Here is another take on the same basic idea, but using the retainer system literally. That is, summoned monsters just occupy retainer slots. Reaction, negotiation, and loyalty rolls are made exactly as if the monster was encountered in the wild. Base rules are 3 LBB OD&D, but I suspect a similar approach would work with other systems. See pages 12 and 13 in Men & Magic and also this old post I wrote about OD&D loyalty and morale.

Monsters defeated in combat may be subdued and brought into service following the rules in Men & Magic. Now, we could pretty much just end there and have a relatively comprehensive system. Magic-users would need to find minions during adventures and convince them to serve or employ charms. However, I like the idea of magic-users being able to gate in creatures directly, and the only even remotely similar spell in Men & Magic is conjure elemental. The monster summoning spells introduced later are not to my taste. So it seems like at least one new rule is required, in the form of a spell that any magic-user could employ if learned:

Summon Monster, level 1 magic-user spell

In a puff of smoke, a monster appears. Use the dungeon random encounter tables, determining first dungeon level* then monster with dice. Establish reaction normally, adjusting for incentives (2d6: 5- hostile, 9+ friendly). Only one monster is summoned. Do not use the number appearing value.

I like the minions that Mateo crafted, but also find the idea of just leveraging everything in the Monster Manuals compelling.

Beyond the new spell, the core of the summoner’s art lies in the skillful application of other standard spells.

Summoned creatures cannot cross a properly prepared circle of protection (requires salt and casting the spell protection from evil). Creatures may be summoned into or outside of such a circle, at the summoner’s discretion.

Other spells that a summoner may want to master: charm person, charm monster.

The dispel magic spell may be used to banish summoned creatures. The “original spell caster level” is the higher of summoner level and monster HD.

The polymorph others spell may be used in conjunction with flesh to stone (using special techniques, they may be cast together, though both must be prepared separately) to transmute minions into figurines, holding them in stasis until recalled using dispel magic (no check required, given that you are dispelling your own enchantment). Such figurines are significant items, and creatures that resist are permitted a single saving throw versus the combined polymorph/stone effect.

Thus, higher level magic-users become better summoners because they are more likely to have all the other spells and be able to set up the summon, ward, compel “combo” more easily and reliably than a lower level conjurer.

In OD&D, I allow magic-users of any level to create scrolls of any spell possessed, even if it is too high level to prepare normally, at the cost of 100 GP per spell level and one downtime action. This rule is based on the scroll creation system in Holmes. It essentially allows ritual casting of higher level spells given time and sufficient GP. Thus, with proper access to spell texts and resources, even a low level magic-user could perform a summoning, but it would be a long, expensive, arduous undertaking, and still entail significant risk.

* Roll 1d6 for dungeon level if using The Underworld & Wilderness Adventures (page 10). The AD&D Monster Manual II probably has the best dungeon encounter tables (page 133), though, so I might use that instead, in which case roll 1d10 for dungeon level. The MMII provides the chance of randomly getting, for example, a duke of hell.

Hazard System v0.2

14 Replies

The Hazard System is the gameplay engine behind The Final Castle. Though it assumes games of fantasy adventure and exploration, it is modular and should be easily adaptable to many kinds of tabletop RPGs. I use some variation on this approach for pretty much every game I run now and I don’t think I could go back to any other method of pacing or timekeeping. It is the natural outgrowth and generalization of the overloaded encounter die.

Gameplay proceeds in turns at different fictional timescales with each turn accompanied by the chance of a hazard. What “hazard” means will vary based on the context. For example, a hazard during a haven turn, when characters are recovering between adventures, might be a natural disaster, while a hazard during a dungeon turn, a much shorter period of fictional time, might be an encounter with a wandering monster. The hazard system also serves as a general timekeeping and resource tracker.

A PDF is also available.

Currently, several references to undefined terminology from The Final Castle remain, such as Ability Tests. It should be relatively easy to interpret these in light of whatever system you are using, but the final Hazard System text will likely be entirely system agnostic. Additional turn types will also likely be included (Domain Turns and Generation Turns, particularly).

Hazard System v0.2

The game proceeds in turns of several different types. The turn types are haven, wilderness, dungeon, and combat. Each represent a progressively smaller amount of fictional time within the game world, though the exact durations are usually abstract. The passage of time within each turn is a resource to be spent wisely, as the hazard die is rolled for every turn that passes to represent potential danger.

The Hazard Die

The six-sided Hazard Die deploys threats, manages resources, keeps time, and tracks light. In short, it is the engine that drives gameplay forward and the heart of the Hazard System. Every significant action, whether in town recovering, traveling through the wilderness, or searching a dungeon corridor for traps, takes a turn. Every turn is accompanied by a roll of the Hazard Die. The exact interpretation of the die result varies by turn type, but the outcomes are conceptually similar. A haven hazard might be a shortage of supplies while a dungeon hazard might be a wandering monster.

Players other than the referee should roll the Hazard Die to make the time cost salient. After rolling the Hazard Die, hand it to another player so that everyone gets a chance. If playing in person, rotating clockwise around the table works well.

Beginning the game

Start a new campaign with the first Wilderness or Dungeon turn of an adventure. Players should choose a clue or quest from the Tavern to pursue. Roll HP following Recovery guidelines to determine initial HP.

Starting and ending sessions

Sessions should begin and end in a Haven if possible. This allows the the players and PCs to vary between sessions. After a session, players should tell the referee if they are going to follow a different clue or Quest during the next session so that the referee can do any preparation required beforehand.

Haven turns

To recover and replenish resources in a civilized refuge, take a Haven Turn. The exact fictional duration of a Haven Turn can be anything from a few days to several weeks. It is rarely necessary to interrogate the details.

Roll the Hazard Die and resolve any hazard
Pay upkeep: accommodation, retainer, property, and so forth
Recover (roll HP, applying accommodation modifiers)
Process retainer loyalty
Reckon XP gained and level up if appropriate
Buy or sell items, repair damaged gear, or recruit hirelings
Optionally, take one Haven Action (scribe scroll and so forth)
Prepare spells
Review rumors and news

Haven Hazard Die results

Complication (introduce at any point during the turn)
Clue about next complication
Abatement of one or more (by referee whim) haven conditions

Ignore results of 4 – 6. Starred complications persist as conditions.

Haven complications
d20	Complication	d20	Complication
1.	Assassination	11.	Insurrection *
2.	PC challenged	12.	Invasion *
3.	Curse *	13.	Jailbreak
4.	Earthquake	14.	Mobilization *
5.	Flood	15.	Monster attack
6.	Falling star	16.	Murderer on the loose *
7.	Famine *	17.	Pestilence *
8.	Fire	18.	PC slandered
9.	PC impersonated	19.	PC item stolen
10.	Inflation *	20.	Winter *

Wilderness turns

Wilderness turns alternate between day and night. Characters taking two non-camp wilderness actions in a row suffer 1 damage and gain a point of Exhaustion. Choose a wilderness action: travel, search, explore, hunt, track, or camp.

Travel

Move the party into an adjacent area or access a known landmark such as a haven or dungeon.

Search, Explore, Hunt, or Track

The party leader makes a Search Test to locate (and enter, if desired) a hidden feature. To Explore, Search without a stated goal. Success reveals a random hidden feature. Track is a Search to follow a quarry. Hunting yields 1d6 rations (adjust for terrain) per hunter. Night applies a -1 penalty to Search, Hunt, or Track.

Camp

Camping requires a bedroll and consuming 1 ration per character. One person may stand watch for each four party members without impairment. Ignore Hazard Die results above 3.

Wilderness Hazard Die results

Encounter (may differ between day and night)
Percept (regarding next encounter)
Locality (mechanical change in environment)
Percept (regarding hidden feature)
Resource exhaustion
Lost

Lost

Travel is no longer an option if a party is lost. Search must be used to locate a landmark before travel can be resumed.

Exhaustion

Each point of Exhaustion imposes a cumulative -1 penalty on all physical Ability Tests. This adds to Encumbrance penalties.

Dungeon turns

Some actions that require a Dungeon Turn include climbing, forcing a door, guarding the party, listening at a door, moving to a new area, searching the current area, and other tasks of similar scope. Each player may take a different action during a Dungeon Turn. Dungeon Turns can represent a fictional amount of time anywhere between a few minutes to an hour, though most commonly are about 10 minutes long.

In practice, the passage of Dungeon Turns can be more fluid than selecting actions by name, resolving any hazard, and iterating. However, always remain cognizant of lurking dangers and call for the Hazard Die whenever significant actions are taken.

Free dungeon actions

Minor actions often do not consume a full Dungeon Turn. Interacting with particular features such as looking under a rug, opening doors that are not stuck, and pulling levers are all free actions. Clever use of free dungeon actions can forestall the Hazard Die and thus decrease risk.

Dungeon Hazard Die results

Encounter
Percept (regarding next encounter)
Locality (mechanical change in environment)
Fatigue (take 1 damage unless the next turn is spent resting)
Resource exhaustion (spell duration, etc)
Light source exhaustion (any or all light sources go out)

Reasonable resolution

Fatigue and light source results may be ignored when they do not make fictional sense, such as during the first few turns of an exploration. Exhausted light sources rarely all go out at exactly the same time, but instead dwindle over the course of the turn, and may be relit given sufficient PC resources.

B/X 5E

5 Replies

Is this not just the new Basic D&D? Not quite.

(If you like this mashup, here’s a one page PDF version.)

Ability scores: 3d6 down the line. Rearrange as desired. Bonuses from B/X (page B7), because the bell curve distribution of +1, +2, +3, with max 18, makes bonuses more special than the 5E linear increase. Ability checks: roll 1d20 <= score (lower better). Skill checks: roll 1d20 +bonus & +proficiency if proficient (higher better; vs. DC 10 most of the time).

Recovery and dying: re-roll HP during each downtime. Save or die when reduced to zero HP.

Classes are the fighter (HD d8), magic-user (HD d4), and thief (HD d6) from B/X but interpreted as makes most sense in light of the below referenced 5E rules. Use fighter XP progression for all classes (page X6).

Turn undead is a first level spell; use B/X rules (page X5). Successful turns, or turn results that are doubles, do not expend the spell. Concentration required. If you want to play a demon hunter or cleric, make a fighter and take the turn undead spell as your first level feat. (Necromancers: substitute command undead.)

Fighters begin with proficiency in all weapons and medium armor. (Yes, medium. If you want to use heavy armor without penalty, you need to spend a feat.)

Magic-users begin with proficiency in daggers and no armor. Spell progression is from B/X (page X6). Roll three starting spells randomly from B/X or some other spell list. You can pick a spell too if that’s what you spend your first feat on. Spell casting in armor without proficiency is impossible.

Thieves begin with proficiency in club, dagger, staff, short sword, sword, short bow, light crossbow and light armor. They also start with proficiency in dexterity (stealth), strength (climb), intelligence (search), backstab (or sniper), and thieves’ tools.

Backstab is only for surprise melee attacks and deals +1d6 damage per point of proficiency. (But see also the sniper feat.) Distraction + successful stealth check = hidden. Attack from hiding = surprise.

Situational modifiers: Use 5E advantage and disadvantage.

Armor: Ascending AC and armors from 5E (PHB page 145). If you do not meet the heavy armor strength requirements, you take disadvantage on most physical tasks (rather than the speed modifier suggested by the 5E rules, because that does not really come into play unless you are counting squares). Shields: proficiency with medium armor grants the ability to use shields passively. Otherwise, a shield is just a weapon and you need to spend an action to get any defensive benefit.

Weapons: From B/X (damage on page B27). Attack bonus: apply your proficiency bonus to attacks with weapons for which you have proficiency. Finesse weapons: (dagger, stiletto, rapier, etc) use the dex bonus rather than the strength bonus for attack and damage. Initiative: group d6, highest wins.

Feats: Characters gain a feat at levels 1, 4, 7, 10, & 13. Yes, first level too. So go crazy with a spell-casting fighter or a swording magic-user. Who needs multi-classing? Or just go fighter/cleave. Choose from the following options whenever you get a feat. (Or roll if feeling oracular.)

+1 to the ability score of your choice (max 18)
Never surprised
+2 HP
Cleave (taking down an enemy in melee grants a free adjacent attack)
Spell and bonus spell slot
Backstab or sniper (ranged backstab) +1d6 damage
Armor proficiency increases one step (none, light, medium, heavy)
Weapon proficiency (or specialization: +1 damage with a particular weapon)
Skill proficiency (5E PHB page 174)
Tool proficiency (5E PHB page 154)

Bonus spell slots can be used to prepare spells of first level or any level that you can otherwise cast.
