Cloaker

While in Bright Light, the monster has Disadvantage on attack rolls.

The monster makes one Attach attack and two Tail attacks.

Melee Attack: +6 to hit. reach 5 ft. Hit: 3d6 + 3 piercing damage.

Melee Attack: +6 to hit. reach 10 ft. Hit: 1d10 + 3 slashing damage.

The monster casts the Mirror Image spell, requiring no spell components and using Wisdom as the spellcasting ability. The spell ends early if the monster starts or ends its turn in Bright Light.

Three illusory duplicates of yourself appear in your space. Until the spell ends, the duplicates move with you and mimic your actions, shifting position so it's impossible to track which image is real. Each time a creature hits you with an attack roll during the spell's duration, roll a d6 for each of your remaining duplicates. If any of the d6s rolls a 3 or higher, one of the duplicates is hit instead of you, and the duplicate is destroyed. The duplicates otherwise ignore all other damage and effects. The spell ends when all three duplicates are destroyed. A creature is unaffected by this spell if it has the Blinded condition, Blindsight, or Truesight.

Wisdom Save: DC 12. target: 60-foot radius, creature.
