Neeko

She mimicks allied champions. She has the obligatory CC every new champion has (which looks like a copy-pasted Ezreal W), a long-range AOE nuke (Ziggs Q without the bouncing) and an Amumu ult. You know, to force her to be a viable competitive pick and to always make her a threat you cant ignore. They had no better ideas unfortunately.

Pretty sure it is something like this,

Q - Damage skill shot with bonus damage after a delay

W - Skill shot that snares/roots/stuns enemies it passes through

E - Copy a champion (Maybe reactivate to split?)

R - AoE nuke around Neeko after a delay

Edit: someone just informed me that the entire kit was shown already

apparently someone already has the ability spotlight. It was in Portuguese I think, but the gist is, her passive is the clone ability, Q is the small aoe skill shot, if it kills a minion it goes again, if it hits a champion it will go again, up to a total of 3 casts, W is the split image, has a 3 attack passive on it, E is a line skill shot that will root the last champion hit, and her ult is a 2 second delay large aoe root that gives her a shield based on damage dealt.

I hope to christ that a portion of damage dealt to clones actually damages the fucking champ. Shaco and Leblanc are already too much of that cancer.
