Polarities Mod/Mantellar Ore

"The world's core trembles..."

Mantellar Ore is a Hardmode ore that begins to spawn in the Underworld once Golem is defeated, replacing Lava in small veins, and is also dropped by s. Touching it will afflict the player with the debuff which deals rapid damage similarly to Hellstone's Burning effect, but much faster and even if the player is wearing the Obsidian Skull or one of its derivative accessories. It requires at least a Drax or Pickaxe Axe to mine.
