Undying the Almighty Dirge is a melee Strength Hero who serves as a formidable tank and a dangerous spellcaster. His abilities force opponents to either kill him or suffer powerful debuffs in a teamfight. Decay is a spammable ability that steals enemies' Strength in an area, making them more fragile and Undying himself more durable as the fight goes on while also being exceptionally potent during the early laning phase, leaving your opponents with mere scraps of health. Soul Rip can act as both a powerful heal or nuke, redirecting the flow of living energy to a target.
By ripping some of the health of his ally or enemy in an area, the target can be healed if an ally, or damaged if an enemy. This is empowered by Tombstone, which acts as a static tank by summoning Zombies to slow Undying's foes while active. With the Zombies summoned, Soul Rip can perform to its fullest, while Decay weakens Undying's foes. Finally, Undying can transform into a horrific Flesh Golem. This transformation increases all allied damage by a significant percentage, and helps keep him alive as his team kills the enemy. Monstrous and truly sadomasochistic, Undying finds great pleasure in keeping himself alive and vital, while his adversaries suffer as he delivers death to the field. With powerful abilities that allow him to perform well in large fights, the Dirge may never cease. [Source: GamePedia]
