Lava Bats are three times more likely to drop this item than Hellbats, so farming for it in Hardmode is more efficient than in pre-Hardmode.The Magma Stone can be thrown into shimmer to change into the Lava Charm.Javelins and Bone Javelins will apply the fire effect, even though they deal throwing damage.Whips are not affected by the Magma Stone, despite being affected by many melee-related stats, and even the other bonuses of the Fire Gauntlet.Though the tooltip does not specifically say so, the fire effect works not only on melee weapons, but also tools that inflict melee damage such as pickaxes, axes and hammers.
