I never realized how potential Killmonger is.. I used Karnak (meh!) Cable (Oh no!) but nothing impressed to one-shot.. My boy right here is rank 4 and level 1 (unloaded a generic gem but no sig stones).. in my opinion, Killmonger is the number one Skill champ once you play him right and being aware of your enemy. I just wanted to show this because lots seemed troubled with this fella..
