The '''The Dark Mage''' or "Book Mages" (to some of the community) is a ranged support [[Enemies|enemy]]. They are mainly known for spending most of their time which focuses on casting dark spells to support and help their enemy allies crumble defenses.
When spawned, Dark Mages will slowly float towards the core, potentially attacking [[Heroes|heroes]] and [[Defense|defenses]] that aggroes them. Their primary attack consists of firing magic bolts at their targets. Alongside that, Dark Mages also possesses three different abilities, which are casted from one of three spellbooks floating by the Dark Mage. Those abilities consists of -
* '''Healing spell (Yellow Book) -''' Whenever a Dark Mage or any nearby enemies are damaged, they will occasionally casts a heal spell that'll restore health to any nearby enemies in a small radius. The amount of health restored is not much to worry for the majority of the game. However, from Onslaught floors 946 onwards this ability becomes dangerously potent as the amount restored is 50 5 times the number of their enemy level.
* '''Cursing spell (Purple Book) -''' Whenever a Dark Mage targets a tower or blockade, alongside firing magic bolts, they will also periodically cast a single-targeted curse bolt that will damage and debuff any tower/blockade the projectile hit as well, making the defense take 100% more damage for a short duration. (Any tower/blockade affected emits a very subtle dark smoke effect.) Curse Bolts ''will'' pass through Reflect Beams.
