Playing against Rengar

How to counter and exploit weaknesses

1

The "!" above your head means Rengar is invisible and nearby — group up immediately.

2

Control wards and Sweeper reveal him in R — place them in teamfights to protect the carry.

3

Don't position near bushes in lane: he leaps for free from bushes.

4

Zhonya's or Guardian Angel are essential for carries — they survive the initial burst.
