I read the comprehensive post of dev's on the new ranged combat system which made it easy to understand.
I can't however find one for melee combat that addresses the formulas for chance to hit, damage, the different weapon types (IMM's is it?) and which moves and or attacks are driven by melee and which by unarmed (eg. I seem to recall someone telling me that sidestep uses unarmed stat and block uses melee).
Is this info available and if so any idea where please?
