When you miss you get angry! As a bonus action one per turn, if you miss an attack, you may throw the weapon you missed the attack with if the target is engaged with you. The target of the missed attack attempts a Dexterity saving throw with the DC equal to 8 + your proficiency modifier + your melee attack modifier for the original attack. If the target fails the attack, the weapon drops in its square and does damage equal to a normal damage. If the weapon does not normally deal damage by itself like a bow, the damage type changes to bludgeoning. On a success, the creature dodges and the weapon is throw 30 feet in a random direction.
