Boss Battles Thread

I appled the 2nd BF, and the exp buff in will's picture is already progressed, whereas with teh first BF, kev casted it just before it died.

Funny how I look the same in both pictures xD But the anal side of me says the drop arrangements are different in the pictures anyways. Plus, the chats are different.

EDIT: Also there's an Elder Wraith playing hide-and-seek behind your quick slots isaac. Not so with will's. Few other shyts and whatever, I could go on and on xD
