Hellstone

Hellstone is an ore that can be found in The Underworld. Mining it requires at least a Nightmare/Deathbringer Pickaxe. Hellstone in the Underworld emits a faint glow and releases a half-tile / of lava when mined. Hellstone tools are among the most powerful that can be acquired in Pre-Hardmode, rivaled only by two fish themed tools that can be caught from fishing, the Sawtooth Shark and Rockfish.

Hellstone inflicts the Burning debuff on players who touch it. Items that protect the player from fire blocks (including the Obsidian Skull, Obsidian Shield, Obsidian Horseshoe, Obsidian Water Walking Boots, Lava Waders, and Obsidian Skin Potions) will allow players to touch it without incurring fire damage. NPCs and Enemies do not receive damage from Hellstone.

Tips

 * Lava can be farmed by repeatedly mining and placing Hellstone in The Underworld.
 * Placing gravity-affected Blocks such as Sand Blocks on top of Hellstone before mining will keep the Hellstone from inflicting damage.

Trivia

 * Hellstone, Meteorite, Luminite, and Obsidian are the only ores that do not have "ore" in the name.
 * It is the only ore whose bar requires a material in addition to its ore.
 * In the real world, is sometimes called "Hellstone".
