ARCANE FORTITUDE [GENERAL]
You are adept at twisting your prepared spells to aid you in resisting physical stress.
Prerequisites: Ability to cast 3rd-level arcane spells.
Benefit: You may sacrifice a prepared spell at any time, as an immediate action, and channel that spell’s energy into an enhancement bonus to Fortitude saves. This enhancement bonus is equal to the level of the sacrificed spell; you retain this bonus for a number of rounds equal to your caster level plus your Intelligence modifier.
