Counter (second version)

If you or any creature within 15 ft is attacked, you or that creature can instead take 1d6 of bludgeoning damage and the attacker will also take 1d6 of bludgeoning damage. This ignores AC and other active spells (does not change based on levels or original damage).

This will only take effect if the attacker is using a melee weapon. This does nothing to spells or ranged attacks.
