While doing TotGC yesterday, I discovered this bug/exploit.
If a Priest with Glyph of Power Word: Shield puts a Shield on a player that has an Arcane Mage's Focus Magic buff and the glyph's heal crits, the mage is awarded Focus Magic's 3% Crit Chance even though the Priest crit (not the target).
Screenshot:
(You see the Glyph's heal crit in the combat log, and the targeted Mage gets the Focus Magic buff. Recount shows that there is only one mage in the raid.
TL;DR version:
- Have your Mage put "Focus Magic" on a player
- Put a glyphed PW:S on that player
- If it crits, the mage gets 3% crit.
- ???
- Profit.
