Amnemis, the Shadowalker

Shadowalker. When Amnemis is in dim light or darkness, she gains a +30 bonus to her speed.

Blindsting. When Amnemis hits a creature that cannot see her with an attack, she deals an extra 2d6 acid damage.

Innate Spellcasting. Amnemis can cast the following Sorcerer spells without using a spell slot or material components, and using Charisma as the Spellcasting ability(Spell Save DC 17, +9 to hit with spell attacks).

At Will: Darkness, Colour Spray, Nathair’s Mischief, Misty Step, Blindness/Deafness

3/day: Hunger of Hadar

1/day: Eyebite, Enervation

Legendary Resistance(3/day). If Amnemis fails a saving throw, she can choose to succeed instead.

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

Bite. Melee Weapon Attack: +11 to hit, reach 10 ft., one target. Hit: 17 (2d10 + 6) piercing damage plus 4 (1d8) acid damage.

Claw. Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 13 (2d6 + 6) slashing damage.

Tail. Melee Weapon Attack: +11 to hit, reach 15 ft., one target. Hit: 15 (2d8 + 6) bludgeoning damage.

Frightful Presence. Each creature of the dragon's choice that is within 120 feet of the dragon and aware of it must succeed on a DC 16 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 dragon's Frightful Presence for the next 24 hours.

Acid Breath (Recharge 5–6). The dragon exhales acid in a 60-foot line that is 5 feet wide. Each creature in that line must make a DC 18 Dexterity saving throw, taking 54 (12d8) acid damage on a failed save, or half as much damage on a successful one.

Acid Gloom(Recharge 5-6). Amnemis summons a cloud of acidic darkness in a point she can see within 60ft of her. A 20ft radius sphere of darkness erupts from the point she chose. This darkness is functionally identical to that summoned by the Darkness spell. Any creature that ends their turn in the darkness takes 2d8 acid damage. The cloud remains for 1 minute, or until dispelled. Amnemis cannot have multiple spheres active at one time.

From the Dark to the Blazing Sun. As a bonus action, Amnemis may end the blindness of any creature she has blinded. If she does, they take 4d6 Radiant damage.

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

Detect(1). The dragon makes a Wisdom (Perception) check.

Tail Attack(1). The dragon makes a tail attack.

Wing Attack(2). The dragon beats its wings. Each creature within 10 feet of the dragon must succeed on a DC 19 Dexterity saving throw or take 13 (2d6 + 6) bludgeoning damage and be knocked prone. The dragon can then fly up to half its flying speed.
