Multiattack

The clockwork mantis makes two serrated blade attacks. If both attacks hit the same target, the mantis can make a bite attack against another target within range as a bonus action.

Serrated Blade

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) slashing damage

Bite

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) piercing damage.

Invisibility

The clockwork mantis turns invisible until it attacks or until its concentration ends (as if concentrating on a spell). Any equipment the mantis wears or carries is invisible with it.
