Shadow Weave

Type of Feat: General
Prerequisite: Must worship Shar. (Clerics taking this class must be have two of the following domains: Darkness, Evil, Fire.)*
Specifics: Add a +1 bonus to the DC for all saving throws of spells you cast from the schools of Enchantment, Illusion, and Necromancy, and spells with the darkness descriptor. You get a +1 bonus on caster level checks to overcome spell resistance for these schools and spells. Your effective caster level for spells you cast from the schools of Evocation or Transmutation (except spells with the darkness descriptor) is reduced by one. The reduced caster level affects the spell's range, duration, damage, and any other level-dependent variables the spell might have, including dispel checks against you. You can no longer cast spells with the light descriptor, no matter what your level is. Such spells automatically fail.
Use: Automatic.

(*If you take this feat as a cleric without the proper domains, you will be asked to retake your feats. If you take this feat as a first level cleric without the proper domains, you will be unable to level up.)
