Shapechanger. The mimic can use its action to polymorph into an ersatz eye 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 Medium or smaller creature adhered to the mimic is also grappled by it (escape DC 10). 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 glass eye.

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

Innate Spellcasting. The mimic's innate spellcasting ability is Wisdom (spell save DC 15, +7 to hit with spell attacks). The mimic can innately cast the following spells, requiring no material components:

At will: detect evil and good, detect magic

3/day each: detect thoughts, find traps, hunter's mark, enhance ability (owl's wisdom only, self only)

1/day each: mind spike

Symbiont Prosthesis. The mimic can function as an ersatz eye.  When embedded in the socket of a missing eye, the mimic can link to its host's optic nerve, dealing 2 (1d4) piercing damage.  While linked, the mimic draws nutrients from the creature's bloodstream.  While the mimic is linked to a creature's optic nerve, it has no actions of its own.  A creature the mimic has linked to gains the following benefits:

• The creature shares the mimic's senses and Innate Spellcasting trait.  It can use use its own spellcasting ability and spell save DC is they are higher than the mimic's, or the mimic's if its are higher.
• When the creature would make a Wisdom (Perception) check relying on sight, it can have the mimic make the check instead.
• Once per day, the creature can use an action to see as if it were wearing a ring of x-ray vision.  It can end this effect as a bonus action.

Removing the mimic after it has been linked deals 2 (1d4) piercing damage to the creature it has linked to if the mimic is removed willingly, or 10 (4d4) piercing damage for each attempt to remove it by force.  Ability checks to remove the mimic by force count as attempts to escape being grappled by the mimic.

Bite. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 3 (1d4 + 1) piercing damage plus 2 (1d4) acid damage.
