Caitlyn Charmed Mid-Ult

caitlyn only has eyes for vi. charm specifically does not work on her.

No, it is not intended.

Try posting it in "report a bug". It probably have something to do with the recent changes to CC.

Looks like you charmed during her cast time (she casted ult right before charm hit her) and not the channeled portion of the skill...I don't know how long the cast time is but your lvl 1 charm only lasts 1 second...if charm is not present during her channeled portion of the ability then her ult will go off...or it could be just be a bug...

Edit: Just for perspective, casting charm an ulting Lux doesn't prevent Lux's ult, it's cast time and not channeled...

^ what he said

my guess is that it's a similar interaction to how cc relates to dashes. ex: if you hook a tristana after she casts her W she will jump regardless of the CC placed upon her. you probably landed the charm in the small frame of time that cait's ult is guaranteed to fire.
