Pros:
+Really Tanky (Almost Unkilleble)
+Pretty good at farming (Thanks to W & E)
+Really good at chasing (Thanks to Q & R)
+Really fun to play :)

Cons:
-Ignite is his worst enemy
-Hard CC is bad on him

Running 12/0/18 on Mundo is OP.Here is why.
Really good at the early game.2% damage is a LOT and helps him farm even more.

Its very good because Keeps him healthy.

The Q spam is REAL!!!

Q = Slow = 2.5% more damage = OP

More Health regen on Mundo is always good

Get this it is always better than speed in the river.

Obvious Pick More Health = More Mundo Points :D

A LOT better than some CD on the Summoners Spells

1 Enemy = 3 Armor & MR Teamfight = 15 Armor & MR = OP

The Best Keystone Mastery for Mundo is Grasp of the undying.It steals 3% of your max health from the enemy champion you attack.Well that is really OP.

It is the best summoner spell ever.You always need that spell


You get that spell to get to lane faster, to gank bot or to join a Teamfight.Pretty Usefull


I dont get ignite, but some people do to get the first blood or something like that.I think teleport is way better
