You channel divine power directly into your spells, strengthening them.
Prerequisites
Channel divinity, able to cast 1st-level divine spells.
Benefit
You can spend a channel divinity use as a swift action to gain a +1 bonus on caster level for all divine spells you cast until the start of your next turn. If the spell directly uses positive or negative energy, and you channel energy of the same type to turn or rebuke undead, the bonus to caster level is increased to +3 for that spell.
This feat has no effect on your arcane spellcasting ability.
