Just some food for thought:
It's a Dynamite Blast that's costs 3 less. The downside is you have to draw 2 chaos tokens, and can't attack from a location away.
Plus side is that you don't take/deal 3 damage to your friends.
To be safe I'd play it in someone with 5 base fight, which is few and far between. Mark and Tony come to mind.
I guess weigh the odds and go from there.
P.s.- Tony gets a free action to engage or fight. If you're already engaged and choose to fight as your extra action, you could do between 4 damage (punch), or 5-9/10 with a weapon- Average w/weapon is 7.5 s Think 7 damage is worth 2 resources? Yes, my friend.
Ok, ok. Sorry. One last cheese.
Tony. Beretta M1918. 5 base, +4 Beretta, +1 vicious blow = 10 Total Fist.
Double, or Nothing... Let's say your average monster has 3/4 Fight. Double is 6/8. I'd feel decent about a 10 vs. 8.
Chaos bag generally has 15 tokens, 5 of which make this attack fail.
So...66% chance of success. Let's just say 70 for giggle. 3 in 4 chance to succeed, almost.
Final damage is 8 as your free action fight. Plus your One-Two punch = 3 damage, for a Final total of 11 damage if the stars align.
11 damage for 2 resources and 1 action. Yes please. Oh, you have 2 actions left btw.
Ps, Ps. Double or nothing One-Two punch at base 5/7 = 6 damage. So it's kinda like a shotgun?
Bang! Bang!
Edit: We all agree that Double or Nothing works with One-Two Punch as being applied to both attacks, as they are both in a single action, yes?
Someone check my math, but yeah.
