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.
Hello, my summoners name is Green Coffe and I made a previous guide on "tank Lucian top" just a fun build to try out of ranked. This one could have the potential to be viable in the near future.
Just try this, I haven't done enough testing to do an in-depth guide, but for the moment it is a good combination of Ekko ap power (6.11 "nerf" in basic damage but "buff" in ap ratio) these items give Ekko enough ap to be an assassin and keep the tankynes and forgiving nature of "tank Ekko"
This build counter would be a team of more than 3 tanks. squishy targets would be an instant kill for Ekko while for enemy tanks, Ekko would still have the dueling power of any fighter/tank.
