A creature affected by this spell exudes an aura that draws a hostile reaction from all animals within 50 feet. Only animals that can be influenced by an animal friendship spell (animals with an Intelligence rating of 1-4) react in this way. When this spell is cast, a single creature determined by the priest during casting must make a successful saving throw vs. spell or be affected. If the saving throw is failed, all animals within 50 feet become hostile to the affected creature. Thus, normally aggressive and temperamental animals instantly attack, while normally passive animals react to moderately dangerous situations as if trapped in a corner or protecting young. (DMs should adjust a given animal's morale by 5 points to determine whether or not it feels threatened enough to attack.)
This spell does not function at its full potential if cast upon rangers or other beings who possess a natural ability that allows them to alter an animal's disposition. This spell simply prevents such beings from changing an animal's emotional state, but the animal does not become more hostile toward the creature. The spell and the natural ability effectively cancel out one another for the duration of the spell.
Similarly, spells that allow a caster to influence animals (e.g., animal friendship, charm person or mammal, etc.) fail when cast by an individual affected by this spell.
Animal animosity lasts for its full duration, unless removed with a remove curse, dispel magic, or a more potent spell.
The use of this spell is the province of Rillifane Rallathil, and those who have been subject to it often refer to it as Rillifane's Curse.
Notes: Granted to priests of Rillifane Rallathil.
