New to ekko

Depends if you want to go AP Ekko or Tank Ekko.

For AP Ekko, I'm using this guide, and I'm quite happy with it. http://www.mobafire.com/league-of-legends/build/6-14-sekkonds-453223 Build is optimized around getting 30% CDR ASAP, to proc your passive easily, potentially only with Q. Key thing to remember is, even with his "bruiser build", you're still pretty squishy. Proc your 3-hit passive and GTFO, don't try to make extended fights while the enemy is still in the immunity period. Just whittle them down and don't be greedy.

For Tank Ekko, the core stuff is Sunfire/IBG/Spirit Visage with Grasp of the Undying as Keystone. You're much Tankier (obviously), so you can stay in the thick of the fight, which helps you proc'ing your passive multiple times, even with the immunity period, makes it easier to use your R offensively by having enough time for your phantom to catch-up with you, and makes it easier to proc your W stun because you can survive long enough to wait the delay, you don't need to predict before even entering the fight.

Your E works on towers. Lichbane is fun. Grab thunderlords. Poke with Q.

And get Visage if they have a lot of AP. Abyssal also, but visage gives you better healing on ult.

Build AP items.

: Or trade out Rylais for another tank item, But i love the slow and health.

Just remember, time is on your side.

tip: stop.
