(Legion Spoiler!) Hidden artifact effect - Windwalker Monk

As previously mentioned in this post (http://ift.tt/1WvF2Xc) there are hidden artifact effects for several classes. Basically, if you fall just a little bit further than the height of your jumps, you will release a shockwave around you: Gif 1: ShockwaveHowever, if there are enemies around you, you will knock them back (without cooldown!): Gif 2: KnockbackWithout my artifact equipped the effect didn't occur.
