|Debuff tooltip||Slowly losing life|
The Magma Stone is an accessory that drops from Lava Bats (2% chance) and Hellbats (0.67% chance) in The Underworld. It causes the wearer's melee attacks to inflict the On Fire! debuff on enemies, and also produces orange flame particles that light up the area whenever a melee weapon is swung. The duration of the On Fire! debuff is random, and varies according to the following table:
- Though the tooltip does not specifically say so, the fire effect only works on melee weapons, including tools that inflict melee damage such as Pickaxes, Axes and Hammers.
- Lava Bats are three times more likely to drop this item than are Hellbats, so farming it in Hardmode is more efficient than in Pre-Hardmode.
- Javelins and Bone Javelins will apply the fire effect, even though they deal throwing damage.
- Desktop 1.2.1: Magma Stone will no longer show a fire effect for non melee weapons.
