Hellstone Bars are bars crafted from Hellstone and Obsidian. They are used to craft some of the most powerful equipment available pre-Hardmode, and remain useful, if not necessary, in dealing with the shift in difficulty upon entering Hardmode. Notably, the Molten Pickaxe is the only pre-Hardmode pickaxe capable of mining the first tier of Hardmode ores, Cobalt and Palladium.
- Hellstone Bars have a special immunity to lava in the game's code, even though their rarity implies this anyway.
