I gave ChatGTP-4 some examples of domains and asked if to produce domains suitable for the Dark Sun setting.
MYSTIC OASIS DOMAIN
Granted Powers: You can use Locate Water (modified Locate Object) as a spell-like ability once per day, allowing you to find a source of water within 400 ft. + 40 ft./level.
- Endure Elements: Exist comfortably in hot or cold environments.
- Fog Cloud: Fog obscures vision.
- Quench: Extinguishes non-magical fires or one magic item.
- Wall of Water (modified Wall of Fire): Creates a wall of water that provides cover and extinguishes fires.
- Mirage Arcana: As hallucinatory terrain, plus structures.
- Transmute Water to Dust (modified Transmute Rock to Mud): Transforms water to dust, potentially causing dehydration.
- Control Weather: Changes weather in the local area.
- Summon Nature’s Ally VIII: Calls a powerful water creature to serve you.
- Oasis Creation (modified Genesis): Creates a small, lush oasis.
Oasis Creation (modified Genesis)
School: Conjuration (Creation)
Level: Druid 9, Mystic Oasis 9
Components: V, S, DF, XP
Casting Time: 1 week (8 hours/day)
Range: Touch
Effect: A small, lush oasis up to 10 ft./level in radius (S)
Duration: Instantaneous
Saving Throw: None
Spell Resistance: No
This spell allows the caster to create a small, lush oasis within the harsh landscape of Athas. The oasis created provides a hospitable environment where vegetation can grow and support life. The oasis features a natural spring, providing fresh water and supporting plant life in the surrounding area.
The created oasis is permanent and cannot be dispelled. However, it can be destroyed through natural or magical means, such as draining the spring, defiling the oasis, or causing an earthquake.
The spring in the oasis can sustain 2 humanoids per caster level in terms of fresh water. For example, if a 17th-level caster casts the spell, the spring can provide enough fresh water for 34 humanoids. The oasis’s plant life can support 1 humanoid per caster level for food resources. Additional humanoids may be able to use the oasis, but the water and food supply will be strained, potentially causing shortages, competition for resources, and even draining the spring if the usage is not properly managed.
You must be present during the entire casting process, which takes one week (8 hours per day). You cannot interrupt the casting process without ruining the spell. The oasis forms at the end of the casting time.
Focus Component: A flask of water from a natural spring and a handful of fertile soil.
XP Cost: 1,500 XP.
Wall of Water (modified Wall of Fire)
School: Evocation [Water]
Level: Mystic Oasis 4, Druid 4
Components: V, S,
Casting Time: 1 standard action
Range: Medium (100 ft. + 10 ft./level)
Effect: Opaque sheet of water up to 20 ft. long/level or a ring of water with a radius of up to 5 ft./two levels; either form 20 ft. high
Duration: Concentration + 1 round/level
Saving Throw: None
Spell Resistance: Yes
This spell creates a wall of water that provides cover and extinguishes fires. The wall is opaque and blocks line of sight, providing total concealment. Creatures attempting to pass through the wall take 2d4 points of nonlethal damage and become soaked, extinguishing any non-magical fires on them. The wall cannot be used to push creatures or objects, and it does not deal damage to structures. However, it can be used to extinguish fires in an area.
Transmute Water to Dust (modified Transmute Rock to Mud)
School: Transmutation [Earth]
Level: Mystic Oasis 5, Druid 5
Components: V, S, M/DF
Casting Time: 1 standard action
Range: Medium (100 ft. + 10 ft./level)
Area: Up to two 10-ft. cubes/level (S)
Duration: Permanent
Saving Throw: None
Spell Resistance: No
This spell transforms water in the affected area into dust, potentially causing dehydration in living creatures and leaving behind dry, barren ground. Creatures caught in the area when the spell is cast must make a Fortitude save or suffer from dehydration, taking 1d6 points of nonlethal damage and becoming fatigued. The spell does not affect creatures with the water subtype.
More to come.
