EDIT: Wisp was nerfed in a recent patch - Tether now applies a 100% Move speed and Attack speed slow instead of a stun - this can no longer be used to interrupt channeling spells and items, as shown in the video. Read more about it here http://dota2.gamepedia.com/Io First try at a guide video, a bit rushed but I feel it went ok - let me know what you think! Any suggestions, criticisms, thoughts and advice are welcome (Reuploaded because a minute or two of the video repeated initially) Dota 2 copyright Valve, IceFrog Song: Silent Motions by morgantj, used under the Creative Commons license http://ccmixter.org/files/morgantj/30058
