Legendary Actions (1). An Augmented Mimic can use one extra action per round. This action can be spent at any point in the round directly after a creature’s turn ends and another begins.

Many Appendages (6). An Augmented Mimic can have up to 6 creatures Grabbed at a time. It can maintain 3 Grabbed conditions with a single action.

Slime. An Augmented Mimic exudes a thick slime that acts as a powerful adhesive, holding fast any creatures or items that touch it. Opponents Grabbed by the Augmented Mimic cannot get free while the Augmented Mimic is alive without removing the adhesive first. A weapon that strikes an Augmented Mimic is stuck fast unless the wielder succeeds on a DC 26 Reflex save. A wielder that fails the Reflex save can attempt a DC 26 Athletics check to needed to pry their weapon off of the Augmented Mimic. Strong alcohol or universal solvent dissolves the slime and can be applied with a successful melee or ranged attack, though the Augmented Mimic can still inflict the Grabbed condition afterwards. An Augmented Mimic can dissolve its slime at will with a free action. The slime breaks down 3d4+2 rounds after an Augmented Mimic dies.

Actions

Change Shape. As a Double Action, an Augmented Mimic can assume the general shape of any Tiny to Huge object, such as a book, a stout bed, or a room, including a damaged or broken version of that object. They can use Deception (reduced to single advantage) to simulate change if another creature interacts with them, such as appearing like they are being damaged if a creature is attacking them. The damage only causes actual damage to the Augmented Mimic if the attack equals or passes the Augmented Mimic’s AC, otherwise, while the Augmented Mimic can appear to take damage it does not actually. If the Augmented Mimic does take damage while using Change Shape, it takes half damage. If it appears as a Durable object, it takes a quarter damage or full damage if it has the Breakable tag or is dealt fire damage while an object with the Flammable tag. For what objects have which tags, see the Break Objects page. The ability to simulate change does not affect areas around the Augmented Mimic so if they are a door, they can open, appear to take damage, or deteriorate but unless they are over an existing opening through a wall, they can only open onto a wall. An Augmented Mimic’s body is hard and has a rough texture, no matter what appearance it might present. An Augmented Mimic can change into another form as a double action or its own appearance as a single action.

Constrict. As part of the same action to maintain the Grabbed condition, an Augmented Mimic can constrict and inflict 3d8+4 bludgeoning damage.

Slam. Melee Strike +16 (unarmed) with 4d8+4 bludgeoning damage and automatically inflicts the Grabbed condition (DC 26) with additional penalties from the Slime ability.
