You may channel divinity to access additional spells.
Prerequisites
Channel divinity class feature, spellcasting with limited Spell Access, caster level 3rd.
Benefit
When you regain your spell slots for the day, you may expend daily uses of channel divinity to gain access to additional spells. When you use this feat, choose one or more spells from your class spell list. You treat these spells as though you had accessed them for the next 24 hours or until the next time you prepare spells, whichever comes first.
You must expend a number of channel divinity uses equal to the combined level of all spells accessed in this way. So, if you choose to access a 1st and a 3rd level spell, you would need to expend 4 uses of channel divinity.
