However, with this madness comes true clarity. Once per minute, as an immediate action, the Preacher may instead gain a bonus of equal size to all wisdom-based skill checks, will saves, and to their AC for 1 round.
Because DM's rarely keep track of time like this (YMMV), why not say once every 10 turns?

An artful bit of homebrew, in any case.
