These spells are inspired by water breathing, teleport, locate object, and dimension door. See spells without levels for more information about this project. The last sentence of portal needs more work, but I think the idea should be clear.
A number of creatures equal to the sorcerer’s level need not draw breath to sustain life for the duration of this spell. Instead, the sorcerer inscribes a breath sigil, and the atmosphere around the sigil is magically transferred to the lungs of the creatures selected during the casting of the spell.
A number of persons up to the sorcerer’s level are transported to the location of the sorcerer’s sigil of return. Carried and worn possessions are conveyed as well, though there is a 50% that any awkward or cumbersome object is left behind. The sigil of return must be scribed under the gaze of the sun and is destroyed if moved from its place of inscription.
Nonliving items marked with the sorcerer’s recall sigil are transported to the sorcerers current location. A number of significant items per level (following encumbrance guidelines) may be recalled.
The sorcerer places a portal sigil on two doors and by the casting of this spell connects them so that they become the same door as long as the sigils endure. A traveller stepping into one steps out of the other, with directionality of travel governed by the facing of the sigil (travellers enter toward the sigil and exit from it). This spell only works on doors of established essence, and is permanent, but closing the door after it has been opened from the sigil side destroys the enchantment and the sigils.
