This is so off meta and I love it. Throwing Heartsteel on Neeko doesn't seem like the best decision, but it's very cheesy when it works.

Hopefully you can use this build and start dominating your games with the strongest tomato that is Neeko!! 🌸

Neeko is best decision!

Neeko has some great abilities! Lets go over each one in depth!

Her Q is the bread and butter of AP damage. It starts with one initial damage proc, followed by 2 other potential hits. These proc under two conditions:
1 - Killing a small minion/unit
2 - Hitting any enemy or big jungle monster
It's important to send your Q a bit behind someone you're chasing so you can proc second hits if they continue running. It's also a powerful CS farming tool, and you should use it occasionally to farm on any build.

"Boa!"

Her W ability sends out a clone of herself, along with her 3rd hit passive. Her clone looks exactly like her or the enemy she is disguised as before casting. You want to trick opponents into attacking the clone in times of running away, or simply use it to gain the extra move speed granted by the active cast.
The passive effect of the W is essential in her AP-ONHIT and AD builds. The charges can be built up on any unit, and the third hit lets out a powerful magic damage bonus to your next attack. It is smart to build this 3rd hit on minions and use it to poke an enemy instead of using regular normal attacks.

"Tricky tricky! You got the wrong Neeko!"

Her E is a powerful root that uses some skill to master. This root does decent damage and has a decent root time, but there's something special to this chameleon's tangle-barb. If her E passes through any unit, it transforms into a more powerful root that lasts longer on any opponent it passes through. There is no limit to how many units can be rooted in the path of the root, and using this longer root through minions is one of her most powerful tools. Leveling up this ability helps with teamfights especially since it can keep a lot of people still for that beautiful Pop Blossom to stun them all!

"No, tail! We must be angry now."

Her bread and butter ultimate is the Pop-Blossom, charging up after a couple seconds and stunning all enemies in a large range, dealing a lot of damage and granting her an adaptive shield. This zone travels with you wherever you go, and you can perform almost any action while channeling it. Start your ultimate channeling, then use your movement tools such as flash and rocketbelt to catch your opponents running away. This ult is concealed while you are in bushes, as well as when you are disguised as an enemy champion!

"Neeko will keep your sho'ma alive."

Thank you for reading my Neeko Guide. I will try and continue to support it through future patches and take in feedback and adjust the builds to make Neeko as simple as possible!
