Feat: Elementalist

Prereqs: The ability to cast three spells with the same elemental descriptor. (Acid, Electricity, Fire, or Cold)

You are adept at wielding one of the elemental forces in your spellcasting.

Benefit: Choose an elemental descriptor with which you meet the feat's prereqs. Spell DCs of that type are increased by one, as are caster checks to overcome spell resistance.
