Build and Runes
More Tanky items:
When Ekko is low hp and you feel that he is about to use his ultimate, ignite him. This will lower the heal.
Ekko will generally buy a Zhonyas, This allows him time to think about his combo aswell as gives his Ghost time to get right where he Zhonyad and BOOM He ults e and goes all out instantly going from 100 to 0 In like 3 seconds, Be very Careful!
In lane, while Ekko’s Timewinder is on cooldown, he is very vulnerable to poke/all-in, since all he will have is a small dash to escape. Try to get close and poke him if he misses it, but if he lands it then wait for the passive stacks to wear off.
Ekko’s Timewinder does more damage on the way back, so try to dodge it when it comes back.
Pick champs who can stun or silence him from using his ult. If you can kill him in one shot, the threat is immediately gone.
Being in a group or clunking up together is very dangerous especially when Ekko has 3 Skills that have AoE Effects or Damage.
His W is powerful and his kit revolved around it, try not to get stunned and wait out the shield he gets from it. Keep an eye on his illusion as you want to try to flash as soon as possible away from it when he starts his ult.
During champion select try to pick a champion with high mobility.( Leblanc, Yasuo) It makes ekko harder to land his skills.
Don’t try to fight him if you are below 30% hp, he will most likely kill you instantly.
