Crystal Beetle (Amethyst)

Adhesive (Object Form Only). The beetle adheres to anything that touches it. A Huge or smaller creature adhered to the mimic is also grappled by it (escape DC 13). Ability checks made to escape this grapple have disadvantage.

False Appearance (Object Form Only). While the beetle remains motionless, it is indistinguishable from a large crystal cluster.

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

Immutable Form. The beetle is immune to all magical and non-magical effects that alter its form.

Ambush Predator. When unseen and unheard, the beetle has advantage on attack rolls.

Pseudopod. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) bludgeoning damage. If the beetle is in object form, the target is subjected to its Adhesive trait

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) piercing damage

Bestow Greed. As an action the mimic can make its body shine beautifully towards a creature within 60 feet, that creature must make a DC 11 intelligence saving throw, or become charmed for one hour, if the creature makes the saving throw, it is immune to this effect for the next 24 hours.

Spiked Shell. As a reaction, the beetle can produce tiny sharp points all over its body, a creature who makes a melee weapon attack towards the beetle suffers 1d4 piercing damage and a creature who attacks without a weapon suffers 1d6 piercing damage. The beetle still takes the full amount of damage.
