FFXIV Endwalker Black Mage
Masters of the Void, Black Mages summon power from a world engulfed in Darkness to suit their needs.
Using blistering fire and chilling ice, the Black Mage prefers to plant their feet and take the time to cast devastating spells.
Spend all of your MP as quickly as you can to deal large amounts of damage, before changing stances and rapidly regenerating it all in a few seconds.
