Burning

Burning is a debuff activated when touching Hellstone, Hellstone Brick, or Meteorite. The player keeps taking damage and their movement speed is reduced until they step off the fire block. Damage is taken at a rate of approximately 30 points per second.

Equipping the Obsidian Skull, Obsidian Shield, Obsidian Horseshoe, Obsidian Water Walking Boots, Lava Waders, or Ankh Shield will protect a player from suffering Burning on contact with the aformentioned blocks.

Trivia

 * Prior to 1.3, all biomes that contain blocks that inflict this debuff had the same music as a Blood Moon.
