At will: Resistance, Thaumaturgy

1/day each: Animate Dead, Antimagic Field, Astral Projection, Blade Barrier, Command, Contagion, Dispel Magic, Divination, Etherealness, Fire Storm, Harm, Hold Person, Silence

The curse lasts until removed by the Remove Curse spell or similar effect.

Flames of Bhaal. Sarevok causes flames to engulf one creature that he can see within 60 feet. The target must succeed on a DC 18 Dexterity saving throw or take 18 (4d8) necrotic damage. This damage can't be restored except by a Lesser Restoration spell or similar effect.

Slash. Sarevok makes a Longsword attack.

Unholy Flame. Sarevok uses Flames of Bhaal.

Channel Bhaal's Hate (Costs 2 Actions). Sarevok unleashes Bhaal's power. Creatures within 30 feet of Sarevok, including ones behind barriers and around corners, can't regain hit points until the end of Sarevok's next turn.
