狱石 是一种能在地狱被发现的一种矿石 ， Mining Hellstone requires at least a 梦魇/死亡使者镐 (≥65% Mining Power) or better. Hellstone in the Underworld emits a faint glow and releases a half-tile of 熔岩 when mined, a full tile on 专家模式. Hellstone tools are among the most powerful that can be acquired in Pre-困难模式, rivaled only by the fish themed 工具 that can be caught from 钓鱼, the 掠夺鲨, 锯齿鲨, and 岩鱼锤.
Hellstone inflicts the 燃烧 减益 on players who touch it. Items that protect the player from fire blocks (including the 黑曜石骷髅头, 黑曜石护盾, 黑曜石马掌, 十字章护盾, 黑曜石水上漂靴, 熔岩靴, and 黑曜石皮药水s) will allow players to touch it without incurring fire damage.
- Lava can be farmed by repeatedly mining and placing Hellstone in the 地狱.
- The 洞穴探险 buff will not light up Hellstone, and the 金属探测器 (and upgrades) will also not show Hellstone nearby. However, the 危险感 buff will. Nevertheless, it can be found easily due to the sparks it produces and its contrast to the ash blocks.
- 在 困难模式, 狱石能被 雷管 和 Bombs 所破坏。
- 狱石, 陨石, 夜明矿 和 黑曜石 是游戏里仅有的四个属于矿物但英文名里不带有"ore"的矿物。
