the Madman of ZaunFighter Tank
Utterly insane, unrepentantly homicidal, and horrifyingly purple, Dr. Mundo is what keeps many of Zaun's citizens indoors on particularly dark nights. This monosyllabic monstrosity seems to want nothing more than pain—both the giving of it, and the receiving of it. Wielding his massive meat cleaver as if it were weightless, Mundo is infamous for capturing and torturing dozens of Zaun's citizens for his nefarious “operations,” which seem to have no overall point or goal. He is brutal. He is unpredictable. He goes where he pleases. He is also not, technically, a doctor.
Adrenaline Rush (DrMundoP)
Dr. Mundo regenerates 0.3% of his maximum Health each second.
Infected Cleaver (DrMundoQ)
Dr. Mundo hurls his cleaver, dealing damage equal to a portion of his target's current Health and slowing them for a short time. Dr. Mundo delights in the suffering of others, so he is returned a portion of the Health cost when he successfully lands a cleaver (doubled on killing blows).
Burning Agony (DrMundoW)
Dr. Mundo drains his Health to reduce the duration of disables and deal continual damage to nearby enemies.
Dr. Mundo gains bonus attack damage based on his missing health, and his next basic attack headbutts his target for additional damage. Passively increases magic resist whenever Dr. Mundo is dealt magic damage or pays a health cost.
Dr. Mundo sacrifices a portion of his Health for increased Movement Speed and drastically increased Health Regeneration.
Try casting Ignite when Dr. Mundo uses Sadism to negate a large portion of its healing.
Try to coordinate high-damage abilities with your allies right after Dr. Mundo uses his ultimate, but if you're unable to kill him quickly with burst he will heal through the damage.
