Funny ability, can knock players off ledges , also kill elites by pushing them over cliffs but unfortunately you might not be able to reach the corpse to loot it which is a shame, could have brought some tactical use of the enviroment into play, but you never know if you would miss out on a good drop
Oh and if you push an enemy over a ledge but they survive, they will run all the way back to you aggro'ing any mobs they meet on the way!.
If you are brave this could be done deliberately, if you have very strong AOE to lure dozens of enemy to you for easy farm, on the 2 occasions this happened to me though, the enemies wer far too strong for me (Sage) I believe this was on Nar Shaddaa where there is an area near the start with humans on 2 floors, I suppose you could use this on enemies that are several levels lower than you though

A great ability when you need a second or two to cast something.
This is an AoE (Area of Effect) ability that will damage all enemies within 8 meters and knock them back.
