The monster deals the listed amount of damage to any number of creatures Grabbed or Restrained by it. Each of those creatures can attempt a basic Fortitude save with the listed DC.
Encase in Wax
Requirements Facade's previous action was to Constrict a creature
Effect Facade encases the creature they just Constricted with wax. That creature becomes Slowed 1 until it takes a 3-action activity to Interact with the wax and peel it off.
Remake Self(arcane, polymorph)
Facade changes their appearance to be similar to any Medium humanoid creature they've seen, though they're still obviously a wax statue and can't use this ability to Impersonate that creature.
Unsettle(arcane, emotion, fear, mental)
Trigger Facade Strikes a creature they've assumed the basic appearance of
Requirements The monster's last action was a successful Strike that lists Grab in its damage entry, or the monster has a creature Grabbed or Restrained
Effect If used after a Strike, the monster attempts to Grapple the creature using the body part it attacked with. This attempt neither applies nor counts toward the creature's multiple attack penalty.
The monster can instead use Grab and choose one creature it's grabbing or restraining with an appendage that has Grab to automatically extend that condition to the end of the monster's next turn.
