The Cayden Calian Tankard style lets you take a drink do a dirty trick with your mug hand 2hen TWF. What happens during a Brawlers flurry when you are technically TWF but can take all those attacks with a single hand?
At 10th level, a Brawler gets 4 attacks. Would using the tankard's ability eat up one attack or two?
Can take all the attacks with one hand isn't must take all the attacks with one hand. You lose one attack doing the dirty trick, that's all.
