Ooze Mimic

Ooze Mimic

Large ooze, neutral

Based off the Mimic Tear from Elden Ring. A strange silver-black ooze that can reshape itself into a perfect imitation of creatures it encounters. Unlike ordinary mimics, it doesn't merely imitate appearances - It reproduces weapons, armor, movement and combat techniques, creating a fluid reflection of its opponent.

Mimic Form. As a bonus action, the Ooze Mimic can transforms into the physical appearance and equipment of one creature it can see within 60 ft. The transformation lasts until it chooses another form or is incapacitated. The Ooze Mimic gains copies of the targets armor and clothing, weapons, nonmagical equipment, movement style and size. Its weapons become extensions of its body and deal the same type and amount of damage as the copied weapons. It doesn't copy spells, magic item properties, class features or abilities.

Perfect Reflection. When the Ooze Mimic copies a creature, it immediately learns that creature's basic attack patterns. Until it changes form, the Ooze Mimic has advantage on its first attack against the copied creature each turn. If the copied creature has Multiattack, the Ooze Mimic can use Mimic Multiattack instead of its normal attacks.

Adaptive Combatant. At the beginning of each of its turn, the Ooze Mimic can alter its body to counter its current opponent. It gains one of the following benefits: 1. Bulwark- +2 AC. 2. Predator- +10 feet of movement and advantage on opportunity attacks. 3. Executioner- +3 damage on melee attacks. 4. Slippery- Advantage on Dexterity saving throws and grapple checks

Ooze Body. The Ooze Mimic can move through a space as narrow as 1 inch wide without squeezing. It can climb difficult surfaces, including upside down on ceilings, without making an ability check.

Regeneration. The Ooze Mimic regains 15 hit points at the start of its turn. If it takes fire or radiant damage, this trait doesn't function until the start of its next turn.

Split Reflection. When the Ooze Mimic is reduced to half its hit points or fewer, it can split its body into two smaller copies. Once per encounter, as a bonus action, it creates a Mimic Fragment in an unoccupied space within 10ft. The fragment has 60 hit points, Ac 16 and uses the same attacks as the original Ooze but deals half damage. The fragment disappears when reduced to 0 hit points.

Engulf. Melee Weapon Attack: +11 to hit, reach 5ft, one creature. Hit: 21 (3d10 + 5) acid damage and the target is grappled (DC 19 Str or Dex). Until the grapple ends, the target is restrained and takes 10 (3d6) acid damage at the start of each of its turns. The Ooze Mimic can only have one creature engulfed at a time.
