Brush Scuttler Incubator

Nature's Hide. While in one of its natural habitats, the scuttler can attempt to Hide even when only lightly obscured by foliage, heavy rain, and other natural phenomena, and has advantage on stealth checks while around such effects.

Broody. While an incubator is in battle, all other scuttlers in the battle are immune to the Charmed and Frightened conditions.

Breathing Room. If the incubator hasn't taken damage since the end of its last turn, it has advantage on Constitution saving throws from its Accelerated Spawning action.

Multiattack. The incubator makes two attacks, and it uses Accelerated Spawning if available.

Pincer. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 14 (2d10+3) bludgeoning damage and the target is Grappled (escape DC 14). 

Accelerated Spawning (Recharge 5-6). The incubator creates a Brush Scuttler Larva Swarm in an unoccupied space adjacent to it. It must make a DC 15 Constitution saving throw or gain one level of Exhaustion and cannot use this ability if it has 3 or more levels of Exhaustion.

Hand Off. The incubator transfers control of its Grappled target to another creature within its reach. That creature can immediately use its reaction to move up to half its movement away from the incubator. This movement is not impeded by having a creature Grappled.

Existential Distress (1/Day). The incubator cries in distress, granting all other creatures with the Nature's Hide trait within 60 feet of it advantage on attack rolls until the end of their next turn.
