The thorned sulfurlord makes two sulfur slam attacks or two fiery spike attacks.

Sulfur Slam

Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 14 (2d8 + 5) bludgeoning damage plus 9 (2d8) fire damage. The target must succeed on a DC 17 Constitution saving throw or be blinded until the end of its next turn.

The World Shall Know Fire (Recharge 5-6)

The thorned sulfurlord targets a creature that has taken fire damage from it within the last minute and causes a burst of fire to expand out from that creature in a 30-foot-radius. Each creature in the area, including the target, must make a DC 17 Dexterity saving throw, taking 35 (10d6) fire damage on a failed save, or half as much damage on a successful one. The fire ignites flammable objects in the area that aren't being worn or carried.
