Traits

Death Throes

When the balor dies, it explodes, and each creature within 30ft of it must make a DC 20 Dexterity saving throw, taking 70 (20d6) fire damage on a failed save, or half as much damage on a successful one. The explosion ignites flammable objects in that area that aren't being worn or carried, and it destroys the balor's weapons.

Fire Aura

At the start of each of the balor's turns, each creature within 5ft of it takes 10 (3d6) fire damage, and flammable objects in the aura that aren't being worn or carried ignite. A creature that touches the balor or hits it with a melee attack while within 5ft of it takes 10 (3d6) fire damage.

Magic Resistance

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

Magic Weapons

The balor's weapon attacks are magical.
