Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
This is a little Guide from myself. I just tested Ekko and i was totally flashed by his passive. I wanted to try, how much dmg his passive can do. So i am not a pro. If you got some tipps for me, just tell!
Try Nashors' Tooth or Rylais and find out whats the best way to become ekkos' passive a massive!
