I managed to pull this off twice in my ranked game. Requirements: Blitz on one team and fizz on the other Build: I don't believe that my build affected it but i had talisman, righteous, mobies, null magic mantle, and cloth armor http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/2565118175/228139222?tab=overview (Thats my match kappa)

How to preform 1: Grab Fizz (I haven't tested it but i pulled the fizz before cancelling his e) 2:Fizz hits e 3:Blitz hits e as fizz hits e 4:Fizz gets knocked up and stays in place while in e

Bug? FIRST CAST: Fizz hops onto his trident towards the target location, becoming Playful untargetable for 0.75 seconds, before splashing onto the ground below him, dealing magic damage to nearby enemies and Slow icon slowing them for 2 seconds.

Fizz should be untargetable in his e, yet blitz can still knock him up?
