Special Abilities

• Antennae: The Derendian moth abomination has advantage on Wisdom (Perception) checks that rely on smell.
• Assimilation: The Derendian moth abomination has six tentacles. Whenever it takes 30 or more damage in a single turn, one of its tentacles is shorn from its body. Whenever a non-undead creature drops to 0 hit points within 200 feet of the Derendian moth abomination, it can use its reaction to sprout one additional tentacle, up to a maximum of ten. Additional tentacles atrophy after one day.
• Legendary Resistance (3/Day): If the Derendian moth abomination fails a saving throw, it can choose to succeed instead.
• Magic Weapons: The Derendian moth abomination's weapon attacks are magical.
• Unbound: The Derendian moth abomination's movement is unaffected by difficult terrain, and spells and other magical effects can neither reduce the moth's speed nor cause it to be paralyzed or restrained.

Actions

• Multiattack: The Derendian moth abomination makes a number of tentacle attacks equal to the number of tentacles it currently possesses, and one beak attack.
• Tentacle: Melee Weapon Attack: +9 to hit, reach 20 ft., one target. Hit: 5 (1d8 + 1) bludgeoning damage.
• Beak: Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 17 (3d10) piercing damage.
• Wings of the Primal Tender (1/Day): The Derendian moth abomination teleports to an unoccupied location within 100 feet, leaving a shimmering outline of its wings in its former location. The shimmering wings flap violently before exploding in a rainbowcolored dust cloud covering a 60-foot radius. Any creature caught in the dust cloud must make a successful DC 16 Wisdom saving throw or be reduced to 0 hit points. Creatures reduced to 0 hit points from this effect regenerate 10 hit points at the beginning of their next three turns.
