Sauce

Displays the source unit of all auras or buffs in the aura tooltip.

Fork of Aura Source. Original description below: 

Displays information about the “owner” of any buff or debuff on you or any other unit in game.

The addon is capable of answering the following questions:

1. Which paladin to beg for update Blessing of Kings expiring in 15 seconds?
2. What mob has put that awful debuff on you?
3. Which priest has just put wings on the tank?
4. Who is that druid healing that pussy retripal you would otherwise pwn… (orly?)
5. Many more like that (but result should match some UnitId to be determined)

If info isn’t shown, then game client has refused to provide information about buff caster.
