Dr. Mundo regenerates 0.3% of his maximum Health each second.
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 half of the Health cost when he successfully lands a cleaver (increased to the full Health cost on killing blows).
Dr. Mundo drains his Health to reduce the duration of disables and deal continual damage to nearby enemies.
Masochism deals bonus damage on Dr. Mundo's next basic attack and increases Attack Damage by a flat amount for 5 seconds. In addition, Dr. Mundo also gains an additional amount of Attack Damage for each percentage of Health he is missing.
Dr. Mundo sacrifices a portion of his Health for increased Movement Speed and drastically increased Health Regeneration.
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.
