Difference between concussion blow and crushing blow

[Chipote]

Hello everyone, I'm sorry about this dumb question, but i searched a lot in the forums and couldn't find an exact answer. What is the exact difference between the mace special move and the sword special move (concussion and crushing).

Thanks!

Concussion halves the targets int, Crushing blows give added damage to the hit

And crushing blow is supposed to do extra stam drain and armor damage i thought

Crushing does double damage to armor and hp.. Dunno about stam drain
