So I did part 2 with hardly a problem but the enemies in part 3 seem ridiculously high level even though I am within the recvendef parameters. They are almost twice as strong as the previous part and there seems to be no easy path. So I am wondering is there some specific strategy I am missing or do I just have to be patient and grind until I have champions powerful enough to power through ?
These are my champions

And these are my masteries. I have no idea how they work so maybe I screwed them up



So am I missing something or am I just too weak?
