Arcane Savant (Feat)

Prerequisites: Int 23, Arcane caster level 21

Benefit: Select one arcane caster class with a caster level of 21st level or higher. When multiclassing, your caster level in that class uses your total character level instead of your class level. This does not affect any other level-dependent benefits such as bonus feats or spells per day, only your caster level.
