Ethereal lashings

While you hold concentration on this spell, as an action, you can make a spell attack roll against a target to touch them. And then decide a direction, this direction becomes the direction of gravity for this target. A creature targeted by this effect must make a strength saving throw against your spell save DC or begin falling in the chosen direction. Objects of size large or smaller automatically fail this check. You can choose to end one or more lashings on a creature on your turn as a bonus action.

The following table details how attaching multiple lashings to a single target in one direction affects the target. If the chosen direction is in the same direction as gravity, then act as if it were one additional lashing than is placed on the target. (so one lashing up and one lashing down would result in normal gravity)
