Through ceaseless prayer and adherence to the tenets of your faith, you have gained a greater connection to the power of your god and the special blessings he bestows upon his faithful.
Prerequisite(s): Domains class feature, Domain Focus.
BENEFIT
Once per day, you can cast any domain spell without expending its use. In addition, you can use a higher level domain spell use to cast a domain spell of a lower level. So for example, a cleric could use his 3rd-level domain spell use to cast a 1st or 2nd level domain spell.
