Which weapons allow for martial arts to switch to standard damage, instead of just fatigue damage? Would the cross over happen at regular-ol' brass knuckles, or would you have to have spike on them (drawing blood/puncturing, as opposed to just bruising) to get your melee attacks into that realm?
I've searched the AToW manual in vain for clarification, and have just relied on "GM discretion" and good sense to make the call. Is there anything official, though?
