Description: Your spells with an alignment descriptor are more potent than normal.

Prerequisites: Relevant Alignment

Add +1 to the DC for all saving throws against any of your spells that have an alignment descriptor (chaos, evil, good, or lawful) that matches your alignment. This bonus does not stack with any other bonus from Spell Focus feats.

Special

This feat can be taken twice, choosing a different alignment descriptor each time.
