Power-farm jungling and effective dueling. By: Riot Jatt
Durability and crowd control
Every 4s your next attack on a champion deals bonus damage, heals you, and permanently increases your health.
Charge up a powerful attack against a tower while near it.
After 10 minutes gain 8 Armor and 8 Magic Resist and increase your total Armor and Magic Resist by 5%.
Every 8 monsters or enemy minions that die near you permanently increases your max health by 0.2%.
+65 health and +9 AP or +5.4 AD, adaptive
Deals bonus true damage to enemies with impaired movement or actions.
Heal for a percentage of damage dealt with your abilities. Increases with each unique takedown.
Grasp allows you to heal substantially mid-fight, and thanks to Mundo's auto-attacking nature from his [E] steroid, Grasp will also provide a decent amount of extra damage.
There is some choice here between Demolish and Font of Life.
Demolish: If you're looking to split push, Demolish increases that threat dramatically allowing you to chop down towers quickly with [E]s AD steroid.
Font: If you're looking to teamfight, Font of Life provides a ton of healing for your team on targets you hit with [Q].
More often than not taking Conditioning in the jungle is incredibly valuable option as you're not pitted against a particular opponent.
If you're picking in to an almost entirely AD or AP comp, take Iron Skin or Mirror Shell here appropriately.
Mundo has an incredibly fast jungle clear and takes advantage of Overgrowth's stacking nature more abruptly.
Look to counter jungle the enemy Raptor camp often to get the most value.
Thanks to Mundo's almost permanent slowing with [Q], Cheap Shot allows you to repeatedly proc the true damage and whittle away any opponent.
The majority of Mundo's damage comes in the form of abilities. [Q]s high base damage will provide a ton of healing and greatly improves your dueling/survivability.
