Heavy Slash Vs Heavy Stab

[Arcell]

I've tried using slash vs stab with daggers and swords and I've never seen consistently more damage with one or the other on either weapon.

You also can't forget it depends on what kind of enemy you are attacking.
When I fight crabs, I use stab=more damage because of his thick shell.
