On page 129 of Petty Gods Revised & Expanded Edition is the god Odxit. I'm currently writing up an old school dungeon crawl through a forgotten shrine to this forgotten god. This has prompted me to wonder what abilities would be unique to the god of unexplained smells, and how would this translate into unique spells for this type of cleric to cast?
The Eldolon of Inexplicable Odor provides its Clerics with the following additional spells. They become available to the cleric per the usual spell acquisition rules particular to your campaign.
Produce Aroma; Range 120', Duration 2 turns/per level. The cleric is able to produce any smell they have experienced directly, pleasant or foul. It will occupy a volume of space up to 30' in diameter.
Seduce; Range 30', Duration 12 turns. Only affects members of the same species as the caster. The cleric is able to produce pheromones which will make the target of the spell have positive feelings towards the caster. Any reaction roll will be at a +2, +4 if making sexual advances.
Befriend Animal; Range Self, Duration 12 turns. The cleric is able to produce pheromones which will make all animals of a similar type to be friendly, or at least not hostile, towards the caster. The effect moves with the caster and extends 30' feet in all directions.
Predict Weather; Range Self, Duration 12 turns. The cleric knows what weather can be expected in the immediate area (10 square miles) for the next two hours.
Conjure Wind; Range 60', Duration 1 round. The cleric casts a gust of wind approximately 50 mph. This gust will do anything a sudden blast of air would cause; candle and torches to blow out, fan a fire, heel over a sailboat, etc.
Wall of Smell; Range 120', Duration 1 round/level. The cleric creates an opaque wall of smell up to 60' long, 20' high and 1' thick. How the wall smells is up to the caster. If the smell is noxious or otherwise intolerable a Save vs. Spells is required for anyone to pass through the magical barrier. If the smell be pleasing those who can smell it must Save vs. Spells or approach the barrier and sniff it for 1d6 rounds. The summoning cleric may choose any person within his range of smell to remain unaffected by this magic.
Kellen Vapor; Range 120', Duration 1 turn/level. This discreet vapor is breathed outwards by the cleric and invisibly charms the target with any chosen emotional state. The cleric is using smell to trigger overpowering or important experiences and past memories which would trigger the chosen emotional state. This doesn't convey any knowledge of the personal experience. It isn't a form of mind reading. Failing a Saving Roll and the degree felt is up to the caster. Pass the Saving Roll and the caster may only add or subtract one (+1/-1) to the next reaction roll against the target.
