Playing against Ekko

How to counter and exploit weaknesses

1

Watch Ekko's ghost clone: that's where his R will bring him back. Place CC or damage at that location.

2

His W has a 3s delay and a distinctive sound — if you hear it, leave the area immediately.

3

Ekko is an assassin: buy HP and MR to survive his initial burst. If he can't one-shot, he has to R out.

4

Don't chase him on his terms — he wants you to pursue him so he can R and burst you on the way back.
