The Heat Spirit is a pre-Hardmode enemy that spawns in the Brimstone Crag. They charge around at high speeds and attempt to ram the player for high damage, and once they leave a small area around the player, they turn to charge back again.


  • The Heat Spirit's appearance resembles the Lost Soul Demon from the game DOOM (2016).
  • It is the only enemy in the Brimstone Crag that does not gain an increase in stats or drop Bloodstone after Providence is defeated.
