Hellstone Bricks require 1 Hellstone and 1 Stone Block to craft. They can also be mined from Underworld structures. Like plain hellstone, players without an Obsidian Skull in their accessory slot will take 20 damage from touching the brick. As with most damaging blocks, NPCs and enemies will not take any damage from contact with Hellstone Bricks.
Unlike (pre-Hardmode) Hellstone itself, Hellstone Bricks are vulnerable to all explosions.
