Channeled Succor is a Cleric feat that allows you to cast one of a number of spells instead of one prepared Heal spell.
You can remove conditions with divine grace. You can sacrifice one heal spell you've prepared in your extra slots from healing font to cast one of the following spells instead: remove curse, remove disease, remove paralysis, or restoration. The spell is heightened to the same level as the heal spell you sacrificed.
This is not an action and has no frequency; it can't be activated as such, it just happens when you want it to. So, how often can it be done per day?
- a) Once per day: You can sacrifice one of your prepared heal spells, not two or three. Next day, none of your prepared heal spells are sacrificed, so you have one to go.
- b) As many times as you have heal spells: You can sacrifice one of your prepared heal spells, so you do. After that, what does the feat say? It says you can sacrifice one of your prepared heal spells. So you do.
- c) Once, ever (not likely): You can sacrifice one prepared heal spell. Next day, ask yourself: Did I already sacrifice one prepared heal spell? Yes, I did, that one time.
