Baal

Aura of False Divinity. A creature that starts its turn within 30 feet of Baal must make a DC 17 Wisdom saving throw, provided Baal isn't incapacitated. On a failed save, the creature is charmed by Baal. A creature charmed in this way can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. Once it succeeds on the saving throw, a creature is immune to Baal's Aura of False Divinity for 24 hours.

Innate Spellcasting. Baal's spellcasting ability is Charisma (spell save DC 17). Baal can innately cast the following spells, requiring no material components:

At will: charm person, cure wounds, disguise self, thaumaturgy, guiding bolt

1/day each: commune, dominate person, insect plague, mass suggestion, raise dead, holy weapon

Magic Resistance. The radiant idol has advantage on saving throws against spells and other magical effects.

Legendary Resistance (3/Day). If Baal fails a saving throw, he can choose to succeed instead.

Multiattack. Baal makes two melee attacks, one with the flail and one with the greatsword.

Flail. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 10 (1d8 + 6) bludgeoning damage plus 18 (4d8) radiant damage.

Greatsword. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 12 (2d6 + 6) slashing damage plus 18 (4d8) radiant damage.

Radiant Strike (2/Day). Baal chooses a point on the ground it can see within 60 feet of it. A 30-foot-radius, 40-foot-high cylinder of bright light appears there until Baal dismisses it as a bonus action. Each creature in the cylinder when it appears or that ends its turn there must make a DC 17 Constitution saving throw, taking 36 (8d8) radiant damage on a failed save, or half as much damage on a successful one.
