i cant seem to find the right setting to get power auras to trigger a sound when i gain holy power from it. it is even possible? its not a buff it just says you grant holy power from eternal glory
Pretty sure it's not possible as without some sort of effect left on the character power auras can't pick it up.
How about setting up an aura that shows when you have 3 Holy Power, when you use Word of Glory the aura will stay lit so you know you can use it again.
