That Time I Got Reincarnated As A Mimic

As a bonus action after hitting with a melee weapon attack, you can make an additional attack against a different creature within 5 feet, dealing half the weapon’s damage die. At C-Rank (Level 5), add your Strength modifier to the damage. At B-Rank (Level 7), the attack deals full weapon damage. You can use this feature a number of times equal to your proficiency bonus per long rest.
