A willing creature you touch grows a pair of plant limbs with serrated leaves for the duration. The limbs are natural weapons with the Reach property, which the target can use to make unarmed strikes. If the target hits with a serrated limb, the limb deals slashing damage equal to 1d6 + your spellcasting ability modifier instead of the bludgeoning damage normal for an unarmed strike.    Until the spell ends, the target can use a bonus action on each of its turns to make an unarmed strike with a serrated limb.
