Hey guys! Just wanted to put a guide out on AP and AD Ekko one shot and how to play him for most of his roles. I also wanted to include my Gunblade-dusblade build, which is a bit unconventianal but very fun :) I've been playing Ekko since release and he has become my most played chammp (lvl 7, 1Lac. mastery points), so I'd like to think I know a thing or two about him. While his popularity and preferred roles/builds may fluctuate, Ekko remains a fun champion.

Pros
Highly mobile
-Great midgame
-Decent waveclear
- 2nd chance with ult
- Long duration stun with shield
Cons
- Weak against silence or cc
- Not so fantastic late game scaling
- Skills can be hard to land
- Fairly squishy (depending on build)

Skill Sequence
After 1st buy use of proper Hextech Revolver is when you use E then auto then Q 3 stack + thunderload crop and he is at 50% of health use it again and again and ward properly if you want to survive .....


And in team fight you will have to land your W 1st to adc then u take him one shot and then Q,E and then run away toward there side and when shadow reach there and ult ...gg

1st Hextech Revolver
2nd sheen and boots
then complete gunblade
then lich bane
boots and duskblade and statikk shiv
last item is optional whatever you love GA or anything

Summary
Playing around power spikes is key on any champion. You must know your weaknesses and strengths.
Early game-
Laning phase can be a bit tough. In most cases, just use your Q to clear waves and farm up until you at least hit level 6. In some cases though, if you hit level 2 or 3 before your opponent you can try to all in them and in most cases you can typically burn an enemy summoner spell. Once you hit 6 though, you can play a bit riskier and use your R to avoid death or get some kills. If you have a wave pushing towards the enemy turret and you think you can execute a clean dive, it can be a great way to force the enemy out of a large amount of cs.
Since Ekko has some nice mobility spells, he is a fairly good roamer, and top lane Ekko can make some nice teleport plays. Roaming can be a great to not only further your lead, but help out some teammates. HOWEVER, make sure you know when to roam. Roaming too much and losing lane is one of the biggest and most common mistakes a player can make. Make sure you check the following before you roam/ teleport:
Is your lane going to be safe if you roam? Are your minions pushed up and your tower is not at risk of being taken?
Has the lane you're gong to been trading? If not, it's not worth your time
Have the enemies you're going to burnt any summoner spells? If they've used their flashes, your chances of getting a kill are much higher. If you gank and force them to burn their flashes, you should probably come back again later. REMEMBER, it is much more effective to gank the same lane consistently rather than sporadically going to different lanes.
Mid game
Mid game is your time to shine! Once you've started to pick up some of your core items, you are a force to be reckoned with. Once you've made sure your lane is taken care of (you've taken the enemy tower and shoved up the wave) you can start to roam around, catch enemies, and help your team take objectives.
Late game
Sadly, you will fall off a bit late game. Once your enemies stack their MR, you will do subsequently less damage, and with the exception of your R your AP scalings on most abilities are't great. But, if you stick with your teammates and fight smartly, you'll be fine. And, if you choose to take Teleport as a secondary summoner spell you can become an effective split pusher, utilizing your wave clear to push sidewaves for objectives while maintaining the ability to join a fight anywhere on the map.

Farming
I normally like to get atleast 120 farm by 15 mins that is my main goal i normally get that easily with my main "ekko" and you should try to get like 100 cs by 15 mins that is a good amount.
