Ok. Testing the game and seeing how reliable a critical strike is to more skilled fighters, this doubt about the effectiveness of armor (Heavy armor) came up.

Can i do zero damage, break my katana against the lacquered armor of my opponent, use my 2 opportunities and still critical strike him?

I believe you just need to succeed on the check to be able to perform a Critical Strike... but I'm trying to figure out if the order of resolution would break the weapon before the Crit is resolved therefore meaning your weapon has no Deadliness since it's destroyed. So. Much. Page. Flipping.

Particularly i would enjoy seeing armor being more protective against critical strike (maybe forcing you to do 1 wound if you want to critical.)

But yeah, good job picking that up, if you strike then critical and a break happens, the severity is normal. If you strike, the weapon breaks and the critical happens, the severity is closer to 0 (Well, lets face it the guy can be a kakita i suppose).

Hard to know how should go.
