Quinn Permanent Ult Bug ft. Tham Kench [GAMEPLAY]
Hopefully this link is viewable, excuse our voices...but it looks like Quinn is still having an issue with being permanently ulted. I saw there was a thread about his started back up in August that featured Quinn and Yorick interacting ult's with each other and as Quinn died in Valor form she spawned and played the rest of the game in that form.
This might be somewhat similar it would seem that when Tahm Kench devours Quinn in Valor form and either the timeout for the ultimate triggers, or if the ally player triggers the ultimate again, Quinn doesn't actually return to Quinn but remains Valor upon being spit back out by Tahm.
As indicated by my friend throughout the clip the ultimate indicator in the bottom right says that his ultimate is still up. After he dies and respawns he remained the rest of the game as Valor without being able to activate the ultimate again to trigger Quinn's return. Hovering over the ultimate while this bug is in play the tooltip text indicates the "Spell is not Available".
Maybe this has to do with a certain type of invulnerability code that attempts to maintain the form of the ally champion that is has been casted on? Not sure I'm only a Front End Developer so this is just my best guess. In any case thought I'd share it.
