Bulwark Beetle

Melee Weapon Attack: + 2 + your Proficiency Bonus to hit, range 5ft., one creature. Hit: 1d6 + 2 + your Proficiency Bonus bludgeoning damage, and a Large or smaller target is grappled (escape DC equals to your spell save DC). Until this grapple ends, the drone can't use its Pincer attack against another target.

The drone inmediately moves 20 feet in a straight line in a direction you choose. If the drone passes through a creature's space, the creature has to succeed on a Strength saving throw against your spell save DC or be knocked prone.
