Double jump above them and glory kill. Easy.

You need to execute a Glory Kill from above an enemy. With most you can just double jump and be high enough.

[General Frost]

jump up and look down at them. works on off with single jump once you have double jump its easy mode.

Baron of Hell and Hell Knights, use stairs - as you can't double jump high enough to "death from above" glory kill them.
