Raised by an ambitious clerk, the first desk mimic aided them with getting work done on time but also clocking in extra hours as needed. Not that the monstrosity was the sharpest nail in the box. However, it understood enough to get things done. Likewise, the mimic became a student of humanoid culture and helped its owner navigate office politics.That wasn't just getting work done on time. It also meant planting evidence, spying on others, and making a few troublesome rivals disappear. Soon enough the clerk got the vaulted position they desired...only to get murdered by a thief in the night. Because of this the desk mimic and its spawn have an intense loathing of late-night 'visitors'.

Shapechanger.

The mimic can use its action to polymorph into a desk or back into its true, amorphous form. Its statistics are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.

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 14). Ability checks made to escape this grapple have disadvantage.

False Appearance (Object Form Only)

While the mimic remains motionless, it is indistinguishable from an ordinary liquor bottle.

File Away.

Allied creatures within 30ft of the mimic may use the mimic's Reaction, if available, instead of their own to take a REaction.

Grappler.

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

Study Buddy.

Allied creatures within 5ft of the mimic gain advantages on Intelligence-related skill checks.

Actions

Multiattack.

The mimic makes two Pseudopod attacks

Pseuedpod.

Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 8 (1d10 + 4) bludgeoning damage. If the mimic 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: 9 (1d10 + 4) piercing damage plus 4 (1d8) acid damage.

Curse of Redundancy Curse.

The mimic targets a creature with an Intelligence of 4 or greater that it can see within 30ft. The creature must succeed on a DC 13 Wisdom save or can only take Action types that its allies within 30ft have taken since its last turn. This effect lasts for one minute or until the mimic is slain. Creatures that are immune to Charmed are immune to this effect.
