the Madman of Zaun
Patch 26.20 · Stats from the 26.18 Master+ sample (2,879 games).
Dr. Mundo, the Madman of Zaun, shrugs off the first crowd control that hits him and heals a share of his missing health at once with Maximum Dosage. Grasp of the Undying was the keystone on most counted Master+ Mundos, whose two leading item paths — the most common and the most successful — both start on Warmog's Armor.

Build percentage damage — flat penetration falls off against the stats it stacks
Avoid extended fights — its sustain grows with every trade it survives
Punish the cooldown — Dr. Mundo is exposed while its rotation is down
Ward the flank — vision is what turns its best opening into a worse one
Respect the spike — Riot rates the kit 5/10, so a practised player gets more out of it than the average

QInfected Bonesaw
EBlunt Force Trauma
Dr. Mundo has been able to more consistently reach his high points in the jungle where he is less concerned about his slow early game. We are looking to curb some of his clear speed to make sure he can’t go where he pleases too quickly and requires some more time to scale up.
QInfected Bonesaw
We overestimated the impact of last patch's Dr. Mundo bugfix, which means our compensation buff overshot as well. That said, we're still happy with where Top Mundo ended up, but Jungle Mundo is now a little over the line, so we're here to deliver a jungle-specific nerf to bring his two primary roles closer to parity.
EBlunt Force Trauma
Dr. Mundo has once again risen up the ranks in popularity due to some very skilled players playing him very publicly. This time, in the jungle! We think Dr. Mundo is appropriately balanced in both roles at the present, but will continue to monitor how he's performing in the coming weeks. All that said, we're shipping a very impactful bug fix in this patch, which will increase his win rate, so we're also preemptively nerfing him a bit. We're happy with his recent reduction in burst damage, which this bug fix furthers, but want to maintain his overall sustained threat, so we're re-buffing his functional attack damage.
Base Stats
EBlunt Force Trauma
Dr. Mundo is a scaling juggernaut who has to wade through a fairly weak early game in order to scale into the ability to go wherever he pleases. And we're happy he's able to go where he pleases, but he's bursting whomever he pleases a bit too easily. We're looking for some power neutral adjustments that take away some late-game burst and give back late-game durability in its stead.
Base Stats
Mundo has been on the weaker side for a few patches now, especially with the recent nerfs to most of his favorite items. Looking to buff up his base HP to compensate for the missing health from items. As a lot of Mundo's kit scales off of his max HP, we expect this base HP buff to carry more value than most champions would get.
Riot's data lists 12 looks for Dr. Mundo with their own art, the base skin included and 18 chroma variants.

Riot Data Dragon 16.20.1. Growth curve: League of Legends Wiki — Champion statistic.
Dr. Mundo, the Madman of Zaun, is a Tank and Fighter champion in League of Legends. Riot rates the kit 5/10 for difficulty, 5/10 for attack, 7/10 for defense and 6/10 for magic. Dr. Mundo spends no resource on abilities and has 12 skins with their own art. Dr. Mundo's magic resist per level of 2.3 is the 2nd-highest of 173 champions on patch 26.20. Dr. Mundo's base magic resist of 29 is the 15th-lowest of 173 champions on patch 26.20 (shared with 1 other).
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.
