-Jumping is a level 1 [[escape spells|escape spell]], and thus the best choice for enhancing that spell branch. (Do not practice jumping in [[Sokoban]], though!) There are very few places where an unpleasant trap will be placed in an unavoidable position (although the back entrance of the [[Castle]] is a notable one), but for those situations it is generally useful. It finds some use in [[speed ascension]]s, where the small speed boost is critical; jumping actually goes faster than [[speed boots]], although the nutrition burn rate is too high to sustain it for long periods of time. (Note that as jumping ends the turn rather than just costing one action, though, continuously jumping means you will see no benefit from speed.)

-In lit areas, or if carrying a light source, jumping makes for an excellent escape (on its own, or combined with a [[wand of teleport]] for escaping from surrounding mobs of monsters). This is a particularly useful strategy on the [[Astral Plane]], where the nutrition cost is mostly irrelevant and there's no further area to preserve teleport charges for. This is most commonly done with [[jumping boots]], but the spell has slightly more range (probably not enough to make up for the Pw cost, though, leaving the boots as the superior source if you don't need the slot for [[speed boots]]).
