(SPOILER)Warp cn be used as an insta-kill move against foes, warping them to another dimension. It can also be used for teleporting out of dungeons, or more specifically, furthur out of dungeons. Say you are in the 3rd floor and Warp is lvl1 and u use it, you will appear in the 2nd floor. So it does not warp you out if you go far down and it is nnot a high enough level.
