Some who favour shields in battle take their use of it as a weapon even further than shield bashes. They sharpen the outer edge of the metal or stone, adapting their tactics to allow for opportune slashes with their off-hand.
A sharpened shield must be made of metal or stone, and can be used to attack in the same way as a shield bash, dealing 1d6 slashing damage. On a critical hit with a shield slash, the target takes 1d4 slashing damage at the end of their next turn.
