I am a destruction lock... And in being such, I am specced 3/3 in Empowered Imp.
"Increases the damage done by your Imp by 15%, and all critical hits done by your Imp have a 100% chance to increase your spell critical hit chance for your next spell by 100%. This effect lasts 8 sec."
I have found that if I get Focus Magic put on the imp, the amount of times it crits increases, thus my amount of guaranteed crits increases, and my dps increases.
Any thoughts?
