Can you use both in one turn? Also, can you use Battle fury and Exploit weakness in one turn?

i'm assuming you mean flurry because battle fury and exploit weakness are both on the damage slot

as to your questions, yes, you can flurry and bcf together, but you can't flurry and exploit weakness (due to flurry granting attacks (BCF) not actions (exploit))

OHH my mistake. Yes i meant fury. Thanks a bunch bro!
