As far as I can tell, our No.1 slot trinket is "Illustration of the Dragon Soul"
There is a tie really for the second best I think as Embrace of the Spider or Dying Curse. Those are the two I currently have equiped. If you are over hit capped, then take the Exiled trinket from badges to replace Dying Curse. ( Which is rare to be hit capped just from gear alone w/o gemming or enchanting for it.)
Now, in our Naxx run last night, the trinket " Extract of Necromatic Power" dropped. I was looking at it and realized that I totally missed this trinket!!! Im FFB 0/53/18, and while idealy it is a godly warlock trinket, the FFB mages have 3 to 4 dots as well that do damage! Living Bomb, FFB itself, Pyroblast from Hot Streak, and Ignites. All 3-4 dots tick off, and gives a chance for the trinket to proc. Thats 750 to 1300 damage per tick.
Not to mention that is Increases Crit by 95, ( which is huge for FFB speck )
What does everyone think? I tried looking this up on www.Maxdps.com and they don't even have that trinket listed!!! not even on the warlock table is it there.
Has anyone tested or run any numbers on this??
