The Fire Vortex was a single target skill that would trap the foe in a vortex of fire, dealing 10% Fire Magic Damage every second. This spell had no duration and could last as long as the caster could provide 6 Mana every second.
Most of the Elementalists had around 600 Mana at Lv22, which meant they could sustain the skill for around 100 seconds, dealing a total of 1000% damage in exchange for all of their Mana.
However, the Elementalists disdained this skill as they had much better options. They could use a variety of other skills to deal triple or quadruple amounts of damage without emptying their Mana.
This skill was deemed mediocre by most of the players but when Samar saw this skill on sale, he immediately bought it for Mochi to learn. He had thought of skills it could be paired with and came up with the combo skill, Golden Fire Vortex.
