Neeko's abilities, from what I can tell.

P: Heckin' Bamboozle

Whenever one of your illusions fades, your next basic attack within X seconds will deal bonus magic damage and, after a brief delay, cause a detonation around the target.

Q: An original spell

• Skillshot magic damage nuke.
• Passes through units.
• Briefly roots targets hit.

W: Here's a Little Lesson in Trickery

• Become invisible for up to 1.5 seconds.
• While invisible, a clone will take over any prior movement commands.
• This clone mimics your current appearance.

E: Chameleon

• Mimic the appearance, apparent stats, and apparent current HP/mana of a target allied champion.
• Lasts until you take damage or cast Nuke, which causes the illusion to instantly fade.

R: Pixie Power!

• Neeko channels Gromp and starts puffing up. She begins charging up energy for a few seconds, gaining a shield.
• Once you finish charging deal enough magic damage to everything around you to murder everything in sight.
• Presumably there is some way to cancel this, either by breaking the shield or by stunning her (otherwise it's scary).
