It's alright.
If we're not destroying weapons, I go first and retcon my first action to simply flurry of blows (average 2 hits at +7 vs AC 16, rounded down to 2 hits, average damage = 17).
1 Ki point down, Fighter takes 17 damage.
On the SS Fighters he action surges and SS with Precise strike and odds are he hits me twice, blowing Action surge and all Sup dice on Precise attack with SS and his Hand crossbow.
I take 17.5 damage in return (deflecting one of those arrows down to 1 point of damage.
My turn is next; I''ll flurry (two more hits hit on average, 17 more damage) and blow 2 Ki to Stun on those two hits.
Have now spent 4 Ki points.
Fighters Con save +6 vs DC 14 =
chances are the Fighter fails at least one save. I'll make it the last save (obvs if he fails the first one, more attacks hit for the rest of the round.
Fighter is now stunned and has taken 34 damage.
I'll spend my last Ki point to Flurry again. Should get 3 hits (thanks to advantage) dealing 24.5 points of damage.
Fighter has taken 60.5 damage on average and is now dead.
Anyone disagree with my math?
