Firemane Angel

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

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

If the angel takes 21 damage or less that would reduce it to 0 hit points, it is reduced to 1 hit point instead.

The angel's innate spellcasting ability is Charisma (spell save DC 18, +10 to hit with spell attacks). The angel can innately cast the following spells, requiring no material components:

3/day each: compelled duel, guiding bolt (as a 5th-level spell)

1/day each: daylight, fireball (as a 6th-level spell)

The angel makes two melee attacks.

Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 10 (1d8 + 6) slashing damage, or 11 (1d10 + 6) slashing damage if used with two hands, plus 22 (5d8) fire or radiant damage (angel's choice).
