Akemi

Grim Harvest (1/Turn). When Akemi reduces a creature to 0 HP, she regains HP equal to the damage dealt.

Syphon Marks. Akemi can place special marks on a target's body that gives her benefits. She has advantage on attacks against the target and deals an additional 1d6 damage. As an action, she can also consume any number of marks, doing so deals 2d12 necrotic damage to the target, before healing both the target and herself for the same damage. The healing does not affect a target that is on 0 HP.

I Will Harvest Your Souls. On the first turn of battle, Akemi cackles maniacally and starts to draw in the power from everyone near her. Each creature within 60ft of Akemi must make a DC 15 Constitution Saving Throw. On a failed save, the creature takes 8d6 necrotic damage, on a successful save, you take half.

Let the Show Begin. On the second turn of battle, Akemi draws power from her necrotic tome and sends it flying across the battlefield. All dead creatures within 60ft of her, stand back up with 1 HP

Embrace My Shadows. On the third turn of battle, Akemi targets two targets within 60ft of her and surrounds with dark shadows, swapping their positions.

I'm Not Done With You. The first time Akemi falls in combat, the runes on her body flare up and she revives herself as an undead version of herself. This new version has the same stats as her old self, but with completely new abilities.

Withering Image. As a bonus action, Undead Akemi stares at a target, forcing them to make a DC 15 Wisdom saving. On a failed save, they take 1d10 psychic and 1d10 necrotic damage and are frightened until the end of their next turn.
