All type of game and server’s
If you hold a shield with 1h weapon, your damage from the heavy shield attack is calculating from your weapon, not shield.
Like an example: predator’s blade + shield. All heavy attack will deal only 1 damage, but shield damage is 40+. In same time shiel bonus attack (shield smash) is not applyed…
You can poison a shield, but when you hit with shield target is not getting poisoned.
Players can not be poisoned from shield attack, but MOBS getting poisoned when THEY HIT YOU in the shield (when you are blocking).
