All Items and Runes explained
Dr. Mundo is definitely one of the most fun tanks in the game. He's pretty easy to pick up and can be an absolute monster in the right drafts.
Whenever the enemy doesn't have Max HP % damage and/or True Damage you should be locking in Dr. Mundo instantly.
Summoner Spells
Because of how your kit is designed you actually benefit a lot more from taking Ghost over Flash. Your passive makes you immune to CC so you don't care if those spells hit you, later into the game picking up the canister generally outheals whatever damage you took. That plus all your damage being from auto attacks or melee AoE passives makes Movement Speed that much more valuable.
Runes
Dr. Mundo is actually very straightforward. You're going to use this rune setup every single game. I'll just briefly explain why these are the optimal runes:
- Grasp of the Undying for infinite HP scaling
- Demolish damage scales with max HP so perfect fit.
- Second Wind is not only more healing but its a % of your missing HP, so more HP = bigger heal.
- Overgrowth is more infinite HP scaling.
- Magical Footwear for free boots so you can hit your spikes sooner but also gives more MS than normal boots.
- Approach Velocity means you move faster towards anyone hit by your Q.
Abilities
Q - Infected Bonesaw, also known as Cleaver, is your main source of damage in lane. You only put 3 points in it since it deals a % of your opponents max HP as damage, so by level 7 your better off maxing E.
W - Heart Zapper is really mediocre early game but has insane scaling. Use it right before taking a bunch of burst damage so you can heal most of it back.
E - Blunt Force Trauma has two parts, a passive and an active. The passive is what makes Dr. Mundo an insane scaling champion by giving you bonus Attack Damage based on your max HP. The active empowers your next auto attack to deal extra damage based on your missing health; this hits like a truck even with only 2 HP items.
R - Maximum Dosage instantly heals a percentage of your missing HP then gives a bunch of MS and healing for a few seconds.
Items
No reason to start anything else, Doran's Shield is perfect for Mundo.
