You can alter the technique of one spell with such skill that it becomes another.
Prerequisites: Ability to prepare spells.
Benefit: Choose two spells that you can cast that are of the same school, and are the same spell level. You can spontaneously convert one spell into the other when you have prepared that spell. At 10th level, any metamagic feats you have prepared one spell with are applied to the converted spell as well.
Special: You can take this feat multiple times. When you do, choose a new pair of spells that you can cast.
A neat little feat for spellcasters. I couldn’t count the number of times I’ve struggled over the choice of two spells to prepare, every dang day. At least this feat can let you switch out the most frustrating choice!
