Wildwing Ripper's Tornado will have an infinite duration if the channel is interrupted by Morph ending
The neutral creep ability Tornado
normally has a max channel time of 40 seconds, and locks the user in a channeling animation while it is out. A bug occurs if Morphling gains and uses this ability while Morphed into a different hero, then waits for the Morph duration to run out while still channeling Tornado. (Example: Morphling uses Morph on Doom
, then casts Devour
on a Wildwing Ripper, then uses Tornado and waits for the Morph duration to end.) If this happens, the tornado summon will remain with an infinite duration, while Morphling will be free to act in a non-channeling state. The player will retain control of the tornado, and it can be moved anywhere on the map. This can be repeated ad infinitum, creating many copies of the tornado summon that will remain for the rest of the game.
