This is the single most powerful spell a Mage can learn; it unleashes a raw destructive force against one opponent. This spell comes at a great cost of mana. All basic attack and area spells are more powerful for in-class users who do not have to fear a counterattack thanks to a group-mate tanking the target.
This single-target damage spell is tenth of ten that mages may learn between level 1 and level 50. Mages can expect to use it continually throughout hero tier to target single opponents, rarely (if ever) using other single-target offensive spells. Characters of other classes, except for wizards and stormlords, will never be able to learn it.
