What is wrong with this Mundo build?
???
My team seen my build and began to basically pelt me to death with rocks until I muted them. The enemy team had only TF to worry about for magic resist, and therefore I did not build MR because I was not worried about TF. In team fights I got ww to ult me, Leona and Draven but the problem was that I kept dieing in teamfights for my team. Am I not suppose to make sure that the enemy team has no cooldowns!? Turns out I did more damage than my Udyr with Sated devour and mostly offensive damage items.

for obvious reasons and most champions deal some kind of magical damage anyways. The rest of the build looks ok but this should've been a priority.
and
are his core items.
then watch everyone be quiet as you one shot that enemy squishy. Soooo goodles on mundo
