Ashunix

Legendary Resistance (3/Day). If the Ashunix fails a saving throw, it can choose to succeed instead.

Cruel Mimicry. The Ashunix can mimic the last words or noises of any of its previous victims.

Astral Terror (1/Day). The Ashunix can project a copy of itself in the astral plane. When this ability is activated, the Ashunix rolls initiative for its Astral form. The form lasts for 10 minutes and is a perfect copy of the Ashunix’s material form. The two forms are separate and do not share health or conditions.

Multiattack. The Ashunix can use its Frightful Presence. It then makes three attacks: one with its bite and two with its claws.

Bite. Melee Weapon Attack: +17 to hit, reach 10 ft., one target. Hit: 21 (2d10 + 10) piercing damage plus 14 (4d6) necrotic damage.

Claw. Melee Weapon Attack: +17 to hit, reach 15 ft., one target. Hit: 17 (2d8 + 10) slashing damage.

Tail. Melee Weapon Attack: +17 to hit, reach 20 ft., one target. Hit: 19 (2d10 + 10) bludgeoning damage.

Frightful Presence. Each creature of the Ashunix's choice that is within 120 feet of it and aware of it must succeed on a DC 21 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the Ashunix's Frightful Presence for the next 24 hours.

Frightful Scream (Recharge 5–6). The Ashunix releases a piercing wave of sound in a 90-foot sphere. Each creature in that area must make a DC 24 Wisdom saving throw, taking 91 (18d6) psychic damage on a failed save, or half as much damage on a successful one.

The Ashunix can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. The Ashunix regains spent legendary actions at the start of its turn.

Detect. The Ashunix makes a Wisdom (Perception) check.

Tail Attack. The Ashunix makes a tail attack.

Wing Attack (Costs 2 Actions). The Ashunix spreads its wings. Each creature within 30 feet of the Ashunix must succeed on a DC 25 Dexterity saving throw or take 17 (4d6 + 10) piercing damage and be knocked prone. The Ashunix can then climb up to half its climbing speed.
