Sorry, just Agility courses.
I got the Reverence Aura, it appears to be the only discounted aura that is actually useful. It gives an invisible +2 prayer bonus, makes you use up prayer points 4-9% slower, and restores (with prayer potions) 1-3 extra prayer points. It's pretty much like a Holy Wrench that doesn't take up an inventory slot.
mabey i should of bought that one... i bought an emote and a title =0
does it stack with holy wrench?
