Exploitation of the Debtors.

As a bonus action, the angel targets a creature charmed by it that it can see within 30 feet of it. The angel deals 11 (2d10) necrotic damage to the target, and the angel gains temporary hit points equal to the damage dealt.

Flyby.

The angel doesn't provoke an opportunity attack when it flies out of an enemy's reach.

Innate Spellcasting.

The angel's innate spellcasting ability is Charisma (spell save DC 19, +11 to hit with spell attacks). The angel can innately cast the following spells, requiring no material components:

At will: command (as a 2nd-level spell), detect evil and good
3/day each: charm person (as a 5th-level spell), darkness, suggestion
1/day: raise dead

Magic Resistance.

The angel has advantage on saving throws against spells and other magical effects.
