Sorry.
This is an old one, gang.
I just can't find the answer.

Can you use Flurry with Haymaker?

How does it work?

I think Veteran Sub-Mariner is a prime candidate...

Nope. Flurry is a Close Combat Action that grants you two free Close Combat Attacks. Haymaker is a Close Combat Action and since you can't give a figure more than one non-free action a turn, they will not work together (this is the same reason you can't Flurry and Incapacitate or Flurry and Exploit Weakness).

I didn't think so, but I'm using it on him anyway.

Thanks.
