Dr. Mundo Build
the Madman of Zaun
Utterly mad, tragically homicidal, and horrifyingly purple, Dr. Mundo is what keeps many of Zaun's citizens indoors on particularly dark nights. Now a self-proclaimed physician, he was once a patient of Zaun's most infamous asylum. After "curing" the entire staff, Dr. Mundo established his practice in the empty wards that once treated him and began mimicking the highly unethical procedures he had so often experienced himself. With a full cabinet of medicines and zero medical knowledge, he now makes himself more monstrous with each injection and terrifies the hapless "patients" who wander near his office.
The most played Dr. Mundo Jungle build on patch 26.21 runs Fleet Footwork with Triumph, Legend: Alacrity and Coup de Grace, plus Approach Velocity and Magical Footwear from the secondary tree. Take Smite and Flash. Start with Gustwalker Hatchling, then build Heartsteel, Boots of Swiftness and Dead Man's Plate, followed by Spirit Visage, Thornmail and Overlord's Bloodmail. Max Q (Infected Bonesaw) first, then E (Blunt Force Trauma), then W (Heart Zapper). It has a 51.6% win rate and a 0.6% pick rate.
