Gehenna is a Hardmode accessory exclusive to Expert Mode. It is obtained from the Brimstone Elemental's Treasure Bag. It occasionally causes fireballs to fall from the sky. These fireballs act in a manner almost identical to the Inferno Fork, leaving behind a lingering red explosion after dying.
- Brimstone fireballs deal a base of 54 magic damage and benefit from magic bonuses. However, their damage cannot be increased through any means.
- The item is named after the area Gehenna, a small valley in Jerusalem where initially some of the kings of Judah sacrificed their children by fire. Thereafter, it was deemed to be cursed.
