Calamity: Heat Eruption

Laing within the Heart of the vulcanic Mountain "Mollo o Metsi", ingraved in an ancient tablet made of Obsidian, an ancient yet powerfull spell lays. Said in legends, this spell brings forth the wrath of hell on any unfortunate creature, within the casters sight. Fire burning brighter than light of the day, crimson as blood itself and hotter than a dragons breath. 

Once a mage wielded this tremondous power and conquered an entire nation, only in seven days. Before he died on a small island, he challenged those, seeking his power, to challenge his trials to obtain the tablet, he ingraved his spell upon. Many tried, but no one succeded. 

This spell ignores Resistance and Immunity counts as Resistance
