Eldritch Surge

Feats

At 3rd level, an eldritch font can, as a swift action, pour more power into her spells and abilities. She can add 2 to the caster level and DC of a spell, or increase her effective arcanist level by 2 when using an arcanist exploit. She becomes fatigued upon using this ability. If she is already fatigued, she becomes exhausted. If she's already exhausted, she cannot use this ability. This ability doesn't stack with spending points from her arcane reservoir to increase the spell's caster level or DC (as the arcane reservoir class feature).
