Counter Jungling with Amumu
I started playing Amumu Jungle recently and started taking the enemy jungle buffs consistently. Surprised how easy it is for a jungler that's not known for counter jungling so I've made a video on how I go about doing it.
In addition to stealing jungle camps, it has the added benefit of demoralizing the enemy jungler because it's pretty embarassing to lose your buffs to an amumu :D
