Cottage Mimic

Ambush Predator. The mimic has advantage on initiative rolls made while in its object form.

Adhesive (Object Form Only). The mimic adheres to anything that touches it. A Huge or smaller creature adhered to the mimic is also grappled by it (escape DC 24). Ability checks made to escape this grapple have disadvantage.

Alluring Aura (Object Form Only). The mimic can innately cast the mirage arcane spell, requiring no components. The spell targets an area centered on the mimic and appears in such a way to encourage creatures to approach the mimic, such as a dense forest with a single path or a lake with a single island.

False Appearance (Object Form Only). While the mimic remains motionless, it is indistinguishable from an ordinary object.

Grappler. The mimic has advantage on attack rolls against any creature grappled by it.

Grasping Pseudopods. The mimic can have up to five pseudopods at a time. Each pseudopod can be attacked (AC 20; 30 hit points; immunity to poison and psychic damage). Destroying a pseudopod deals no damage to the mimic, which can extrude a replacement pseudopod on its next turn. A pseudopod can also be broken if a creature takes an action and succeeds on a DC 18 Strength check against it.

Legendary Resistance (3/Day, or 4/Day in Lair). If the mimic fails a saving throw, it can choose to succeed instead.

Multiattack. The Cottage Mimic makes three Stomp attacks and one with its Pseudopod. It can replace two Stomp attacks with either a use of it's Spit Acid or Swallow feature.

Pseudopod. Melee Attack Roll: (+16 to hit, reach 60 ft., one creature. Hit: The target is grappled (escape DC 24). Until the grapple ends, the target is restrained and has disadvantage on Strength checks and Strength saving throws, and the mimic can't use the same pseudopod on another target.

Spit Acid (Recharge 5–6). Dexterity Saving Throw: DC 24, each creature in a 60-foot cone. Failure: 36 (8d8) acid damage. Success: Half damage.

Stomp. Melee Attack Roll: +16 to hit, reach 10 ft. Hit: 12 (1d6 + 8) bludgeoning damage and the target must succeed on a DC 24 Strength saving throw or be knocked prone

Swallow. Melee Attack Roll: +16 to hit, reach 10 ft., one Large or smaller creature the mimic is grappling. Hit: 21 (6d6) piercing damage, the target is swallowed, and the grapple ends. The swallowed target is blinded and restrained, it has total cover against attacks and other effects outside the mimic, and it takes 7 (2d6) acid damage at the start of each of the mimic's turns.

If the mimic dies, a swallowed creature is no longer restrained by it and can escape from the corpse using 10 feet of movement, exiting prone.

Retract Pseudopod. The mimic pulls one creature it has grappled with it's pseudopod up to 30 feet towards it. If the target is pulled within 10 feet of the mimic, the mimic can make a swallow attack as part of this action.

Shape-Shift. The mimic [Tooltip Not Found] to resemble a building, including interior details, while retaining its game statistics, or it returns to its true blob form. Any creatures inside the mimic while it is in its building form are automatically swallowed when it transforms into its amorphous form. Likewise, any creatures that the mimic has swallowed find themselves inside a small building when it transforms into its building form. It reverts to its true form if it dies.

Legendary Action Uses: 3 (4 in Lair). Immediately after another creature’s turn, the mimic can expend a use to take one of the following actions. The mimic regains all expended uses at the start of each of its turns.

Earth Pound. The mimic makes two stomp attacks.

Pseudopod Strike. The mimic makes one pseudopod attack, then immediately uses it's retract pseudopod action if it can.

Rampage. The mimic moves up to half its speed in a straight line. It makes one stomp attack against each creature whose space it moves through.
