This page uses a pinned Data Dragon snapshot. It is not a verification of every in-game interaction or hotfix.
Stats and stacks calculate the state you enter. Nine outputs that cannot be derived from the source require in-game values. Special copied or possessed recasts and transfer restrictions are outside full simulation coverage.
This catalog covers normal Summoner’s Rift. Excluded does not mean removed from the game. The classification and its source are listed below.

Variable valuesScaling & formulas
Dr. Mundo resists the first Immobilizing effect that hits him, instead losing 4% current Health and dropping a chemical cannister nearby for 7 seconds. Moving over it reduces this Ability's Cooldown by 15 seconds and restores 4% max Health. Enemy champions moving over the cannister destroy it.
Dr. Mundo regenerates 0.4%（(Lv1–6: 0.4–0.65 / Lv7–12: 0.75–1.25 / Lv13–15: 1.4–1.7 / Lv16–20: 1.9–2.7)%） max Health every 5 seconds.
Dr. Mundo hurls his bonesaw, dealing 20% current Health magic damage to the first enemy hit and Slowing them by 40% for 2 seconds.
If the bonesaw hits a champion or monster, Dr. Mundo restores (1 × 50) Health. If it hits a non-champion or non-monster, Dr. Mundo instead restores (0.5 × 50) Health.
Dr. Mundo charges up a defibrilator, dealing 20 magic damage each second for up to 3 seconds to nearby enemies. Additionally he stores 80%（(80–95 (Lv1–18))%） of damage taken for the first 0.75 seconds and 25% for the remaining duration as gray health and can Recast.
Recast: Detonate the defibrilator, dealing (20 + 7% Bonus health) magic damage to nearby enemies. If this hits at least one champion, Dr. Mundo restores 100% of gray health, otherwise he instead restores 50% of gray health.
Passive: Dr Mundo gains 2% Maximum health Attack Damage.
Active: Dr Mundo violently swings his "medical" bag, causing his next Attack to deal an additional (5 + 5% Bonus health) physical damage, increased by up to (140 + -100)% based on his missing Health. If the enemy is killed, Mundo swats them away, dealing (5 + 5% Bonus health) physical damage to enemies they pass through.
Dr. Mundo pumps himself with chemicals, gaining 15% of his missing Health as max Health, 15% Move Speed, and regenerating 20% max Health over 10 seconds.
At Rank 3, both healing effects are increased by an additional 5% per nearby enemy champion.
