An animal protected by this spell is overlooked and cannot be directly attacked any creature that fails a saving throw vs. spell. If the protected animal attacks, this effect is immediately negated. In any case, attack rolls and damage against an animal protected by this spell suffer a -4 penalty for the duration of the spell.
The material component is a feather, bit of fur, or a scale from the animal to be protected.
Notes: Very rare for druids and similar priests. (Updated from Polyhedron Newszine.)
