Sickly Eshmok

+1 Status to All Saves vs. Magic —

Harmony Vulnerability — An eshmok's wrathful infestations defines them, and forcing peace upon them wrenches at their soul. If they fail a save against calm or a similar effect forcing them to be peaceful, an eshmok takes 4d6 mental damage.

Change Shape (concentrate, divine, polymorph) — The eshmok turns into their fungus form or back into their normal humanoid wasp form. In fungus form, they lose their fly Speed and can't make stinger Strikes. In fungus form, they gain a tendril melee Strike (+21 for 2d8+9 slashing plus eshmok infection); the tendril strike has the agile, magical, reach 10 feet, and unholy traits.
The monster changes its shape indefinitely. It can use this action again to return to its natural shape or adopt a new shape. Unless otherwise noted, a monster cannot use Change Shape to appear as a specific individual. Using Change Shape counts as creating a disguise for the Impersonate use of Deception. The monster's transformation automatically defeats Perception DCs to determine whether the creature is a member of the ancestry or creature type into which it transformed, and it gains a +4 status bonus to its Deception DC to prevent others from seeing through its disguise. Change Shape abilities specify what shapes the monster can adopt. The monster doesn't gain any special abilities of the new shape, only its physical form. For example, in each shape, it replaces its normal Speeds and Strikes, and might potentially change its senses or size. Any changes are listed in its stat block.

Eshmok Infection (mental, poison) — A creature that's Quickened by eshmok infection can use the extra action each round for only Strike actions. A creature that's Confused by eshmok infection never considers an eshmok in fungal form as a target

Saving Throw DC 26 Will

Maximum Duration 6 rounds

Stage 1 confused (1 round)

Stage 2 confused and quickened (1 round)

Stage 3 confused, Off-Guard, and quickened (1 round)

Infesting Exhalation (olfactory, poison) — The eshmok exhales a wave of stinging fiendish wasps out in a 30-foot cone, dealing 4d8 poison damage to every creature within the cone (DC 28 Reflex save). The swarming fiend wasps linger in the area for 6 rounds or until the eshmok is able to use Infesting Exhalation again, whichever comes first. Each creature damaged by Infesting Exhalation or that enters the area must succeed at a DC 28 Fortitude save or take 2d8 persistent poison damage and become Clumsy 1 as the poison renders them dizzy and nauseous. At the end of each of their turns, they can attempt a new Fortitude save to end the effects. The eshmok can't use Infesting Exhalation again for 1d6 rounds.
