Special Traits

• Immaterial Fire. The shape of fire can move through a space as narrow as 1 inch wide without squeezing. A creature that begins its turn within 10 feet of the shape of fire takes 22 (4d10) fire damage. In addition, the shape of fire can enter a hostile creature’s space and stop there. The first time it enters a creature’s space on a turn, that creature takes 22 (4d10) fire damage.
• Innate Spellcasting. The shape of fire’s innate spellcasting ability is Constitution (spell save DC 24). It can cast the following spells, requiring no material components.
  • At will: fireball (5th level, 11d6 fire damage)
  • 3/day each: fire storm, incendiary cloud
• Turn Resistance. The shape of fire has advantage on saving throws against any effect that turns undead.

Actions

• Multiattack. The shape of fire makes two Touch attacks.
• Touch. Melee Weapon Attack: +15 to hit, reach 10 ft., one target. Hit: 29 (4d10 + 7) fire damage. If the target is a creature, it must make a DC 24 Constitution saving throw or be cursed for 1 minute. While cursed, at the beginning of each of the creature’s turns, it must repeat the saving throw. On a successful saving throw, the creature is still cursed but suffers no other effects. On a failed saving throw, the target’s maximum hit points are reduced by 22 (4d10), and the shape of fire regains an equal amount of hit points, up to its maximum. A creature whose maximum hit points are brought to zero by this curse is slain. The curse can be ended early with magic such as remove curse. Lost hit points can only be restored by magic such as greater restoration, heal, regenerate, or wish. If a humanoid creature is slain by the shape of fire, it rises as a lavawight at the end of the shape of fire’s next turn. The lavawight is under the command of the shape of fire, and the shape of fire can have no more than 12 lavawights under its command at a time.
