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.
- The brimstone fire and fireballs deal typeless damage. They are boosted by the average of player's class bonuses which stacks additively with bonuses to 'all damage', such as the Avenger Emblem.
- Brimstone fireballs have a base damage of 54.
- 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.
