Hellstone

Hellstone is an ore that can be found in The Underworld. Mining it requires at least a Nightmare/Deathbringer Pickaxe, and it cannot be mined with in pre-hardmode. 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 three tools that can be caught from fishing, the Sawtooth Shark, Rockfish, and Reaver Shark.

Hellstone inflicts the Burning debuff on players who touch it. Items that protect the player from the debuff (including the Obsidian Skull and its derivatives) 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.
