Sky High Achievement in Mass Effect 3
Lift 100 enemies off the ground with powers.
How to unlock Sky High
Lift is not actually a power itself. There are a few powers that make enemies fly off their feet. Examples would include Throw, Pull, Biotic Charge, Concussive Shot and Singularity. Despite lifting enemies in the air before dropping them, Slam does not.
Note: Even after dying, the ones you have obtained count. They count across all playthroughs as well as multiplayer (which you can play by yourself). Must be done by your Shep! Squad uses do not count.
