My friends and I discovered a bug where during Grey Talon's ultimate, he is invulnerable to opponents' skills and ultimates. View attachment Grey Talon Ult.mp4
He is also immune to melee attacks while controlling the bird. Found out the hard way a long time ago and the problem still persists
Maybe it is a bug since the player character is now understood as being the bird and not the character standing (which can't be controlled during that time and is therefore disregarded by the game logic)
