Cabinet Shell: The monster receives 2d8 less damage from all non-magical or psychic attacks. Attacks that are lowered to 0 or below by this trait will deal at least 1 damage.

False Cabinet: When the monster remains motionless, it is indistinguishable from a piece of its local landscape, as long as the area can be considered somewhat fitting for an arcade machine.

Hide Away: Arcadenid may hide in a new location if they succeed a stealth roll of 14 or higher.

On a fail, Arcadenid fails to hide and suffers disadvantage against the foe's next attack.
