Undying

Undying, also known as Dirge, is a melee strength Hero who serves as a formidable tank; his abilities forcing opponents to either kill him first or suffer powerful debuffs in a teamfight. Decay is a spammable skill that reduces the enemies' Strength, making them more fragile as the fight goes on. Soul Rip can act as both a powerful heal or nuke. This is empowered by Tombstone, which acts as a tank in itself by summoning Zombies to slow Undying's foes while it is alive. Finally, Flesh Golem increases all allied damage by a significant percentage, and helps keep Dirge alive as his team kills the enemy.

Undying has excellent presence in teamfights, but has a poor laning phase and is item-reliant. Target priorities and positioning are a must. Above all, Undying benefits from good allies who know his capabilities and can coordinate with the player. He is recommended for intermediate to advanced players.

Zombies

Trivia

 * Undying was originally an Intelligence Hero and was given Necrolyte's Heartstopper Aura. His skillset was completely changed upon becoming a Strength Hero, and Heartstopper Aura was returned to Necrolyte's skillset.
 * Undying references to several special infected, several campaigns and even the title of the Left 4 Dead series.
 * Undying also references the Half Life series in a rival line towards Tinker. Dr Kleiner, who shares his voice actor with Tinker, has a pet headcrab called Lamarr. Headcrabs are small, parasitic creatures, whom attach themselves to the head of their victims, after which the victims turn into zombies.
 * Undying's Invoker response is a reference to the 6.72's leaked changelog, where Invoker's name 'Kael' had been mistakenly translated into 'Carl'.
