short description: to go out of combat jump right on wall, then walk to the left side, blink/autounstuck/shadowstep/charge/intercept or whatever through the invis. wall, follow the way.
why i use blizzard in 3:00? To show, that on non-walkable ground, all blizzard shards fall on the same point. nice trick for exploration. and yes, 4:40 is epic fail.
