Chompy

Shapechanger. Chompy can shift between a chest-like object, a hound-like mimic form, or its amorphous true body. Its statistics are the same in each form.

False Appearance (Object Form Only). While motionless, Chompy is indistinguishable from an ordinary object such as a chest, barrel, or doorway.

Educated Beast. Bred by the archmages of Ythryn as companion and servant, Chompy has advantage on Intelligence (Arcana) checks to recognize magical symbols, constructs, and command sigils, and it can follow complex spoken or mental instructions.

Telepathic Mimicry. Chompy communicates telepathically within 30 feet using only very short phrases of five words or fewer. Typical phrases include “name?”, “eat?”, “my name Chompy,” or simple answers to commands.

Prestidigitation. Chompy can cast prestidigitation at will, requiring no components. Charisma is the spellcasting ability (spell save DC 12). It commonly uses this to clean objects and surfaces, deodorize refuse, and make small sensory effects in its “trash hound” role.

Adhesive Bite. On a hit with its Bite, the target is grappled (escape DC 15) if it is Medium or smaller. Until this grapple ends, Chompy has advantage on Bite attacks against that target and cannot use Bite on another creature.

Eyes That See. Chompy has advantage on Charisma (Deception) checks made to appear harmless, friendly, or domesticated.

Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 2d10 + 4 piercing damage plus 1d8 elemental damage (fire, cold, or lightning; chosen at the start of Chompy’s turn). If the target is grappled by Chompy, Chompy regains hit points equal to the elemental damage dealt.

Tentacle-Lash. Melee Weapon Attack: +6 to hit, reach 15 ft., one target. Hit: 2d8 + 4 bludgeoning damage, and the target must succeed on a DC 14 Strength saving throw or be pulled up to 10 feet toward Chompy.

Elemental Bark (Recharge 5–6). Chompy releases a chaotic howl. Each creature of Chompy’s choice within 20 feet must make a DC 15 Constitution saving throw, taking 3d8 thunder damage plus 3d8 random elemental damage on a failed save, or half as much on a success. Roll a d4 for the elemental damage type: 1 fire, 2 cold, 3 lightning, 4 force.

Spellcasting. Chompy is a 1st-level spellcaster. Its spellcasting ability is Charisma (spell save DC 12, +4 to hit with spell attacks). Chompy knows the following cantrip:

Chaotic Pounce. If Chompy moves at least 20 feet straight toward a creature and then hits it with a Bite on the same turn, the target must succeed on a DC 15 Strength saving throw or be knocked prone.

Quick Clean. Chompy targets a 5-foot cube it can see within 10 feet and instantly cleans it with prestidigitation. Nonmagical difficult terrain made of debris in that cube is cleared until it becomes soiled again.

Sticky Step. When a creature within 5 feet of Chompy that is grappled by Chompy attempts to escape, Chompy imposes disadvantage on that creature’s ability check.

Opportunity Attack. Chompy makes one melee attack against a creature that provokes an opportunity attack from it.

Seize!
When a creature within 10 feet of Chompy makes a weapon attack, Chompy can lash out with adhesive tendrils.
The attacking creature must succeed on a DC 15 Strength saving throw or have its weapon arm grappled. While grappled this way, the creature has disadvantage on weapon attacks until the grapple ends (escape DC 15).

Guard!
When a creature within 5 feet of Chompy’s master is targeted by an attack, Chompy can interpose its shifting, sticky body.
The attacker rolls with disadvantage. If the attack still hits, Chompy can choose to take the damage instead, its mimic flesh rippling to absorb the blow.

Apprehend!
When a creature moves within Chompy’s reach, Chompy can lash out with its adhesive maw.
Chompy makes one Bite attack. On a hit, the target must succeed on a DC 15 Strength saving throw or be grappled and knocked prone as Chompy drags them down in a tangle of pseudopods and teeth.
