I can't say for sure Tanker. I didn't use the Warlock in IB at all until it was the last day or two, and it ends up that I didn't have the Chest piece unlocked for that character, so I didn't want to risk using him in the IB and then not having the kills count towards the ornament, if it was tied to unlocking the chest piece. Anyways, I am glad there is another IB before season three. I thought it was pretty lame for a challenge with those kind of numbers. Mind you, if I was conscious of the ornament challenge from the beginning, I probably would have played differently.
