Aria Specter

Arcane Crescendo. While concentrating on a spell, the Aria may use a Bonus Action to continue singing the vocal components of that spell. Until the start of her next turn, creatures have Disadvantage on their saves against it.

Cadenza. When Aria would be reduced to 0hp for the first time, she is instead reduced to 1hp. Her abilities recharge, and she may immediately take an action.

Care Selve. Aria has resistance to psychic damage.

Incorporeal Movement. Aria can move through other creatures and objects as if they were difficult terrain. She takes 5 (1d10) force damage if she ends her turn inside an object.

Thunderous Tessitura. Aria projects a violent vocalization. Ranged Spell Attack: +4 to hit, reach 30 ft., one target. Hit: 12 (3d6 + 2) thunder damage.

Coloratura (Recharge 6). Aria may cast Hypnotic Pattern without using a spell slot. When doing so, she sings until the start of her next turn, the spell is centred upon her, and it does not affect undead.

Killing Aria (1/Day). Aria releases a powerful solo performance, provided that she is in bright light. This song has no effect on constructs and undead. All other creatures within 30 feet of her that can hear her must make a DC 13 Constitution saving throw. On a failure, a creature drops to 0 hit points. On a success, a creature takes 10 (3d6) psychic damage. Aria continues singing until the start of her next turn.
