What class are you going with this?
Drill Katar casts full divest, it'll work on anyone who isn't FCP'd but I believe the suggestion was specifically for RGs. (no EDP at first so the reflect isn't too much to deal with, then after you divest you EDP + glorious to kill.)
Personally, I'd rather just oblivion curse/dark crow and let someone else do the killing on a full tank.
