The club should not cause bleed, i understand a good impact will make someone bleed a small bit but not as much as getting stabbed or slashed
instead i think it should get a unique effect when you hit them with a heavy attack. It concusses them causing their vision to blur slightly, worsening with every heavy strike
the symbol will be a red cracked skull in the ailment area to let the player know they have been concussed. Cold magics like ice or water will stop a concussion similar to how fire and hot magics will stop bleed
