Quick and easy tips to spot Neeko out
How do you know when Neeko goes invisible while spamming a clone?
Easy. When she goes invisible and spams a clone, both the clone and her get a movement speed, and that makes her animation go on all fours. So if you ever see Neeko goes on all fours, then it's probably a clone, and ignore it.
How do you know when Neeko clones into one of her teammates?
Easy. If an squishy with 10% hp is charging at your full hp whole team without a care in the world, you can assume that it's either a bot or it's Neeko charging at you with her unstoppable ult.
And third and last tip, if you can't see Neeko on the map, assume everyone is a Neeko.
