|Any 敵怪 in 洞穴 and 地獄||1||.25%|
The 獄火球 is a 困難模式 悠悠球 that has a 1:400 (0.25%) chance to be dropped from any 敵怪 in the bottom half of the 洞穴s or 地獄. It has a chance to inflict the 著火了！ 減益. It can be considered the Hardmode upgrade of the 噴流球.
Its best 修飾語 is 神級.
- While not as powerful as 冰雪悠悠球, Hel-Fire is arguably easier to acquire (as the Underworld is initially unaffected by entering Hardmode) and can be a great early-Hardmode option for yoyo users or melee players in general.
- Using the Hel-Fire while wearing 寒霜盔甲 allows you to damage enemies with both the On Fire! debuff and inflict 霜凍 debuff.
