Babcock's Brawling Blows

A legendary technique taken from Babcock's experience in the Royal Marines, it is generally considered to be "fighting dirty" amongst the spellcasting community - but you try telling the boots on the ground that their method is "inelegant" and "lacking in finesse".

For the duration, you can use your spellcasting ability instead of Strength for the attack and damage rolls of melee attacks using unarmed strikes, and the damage die becomes a d6.
