Gain your move speed and declare a destination within your current available movement, then make no less than a 10' run up in the correct direction...
If you are standing on unstable or slippery terrain, make an agility saving throw. If you fail, fall prone and end this action.
Make an agility check. The DC of this check is the distance of the jump in feet. On a success, you jump to your destination. On a failure, you only move the corresponding distance in feet before stopping.
If you land in difficult, unstable, or slippery terrain, or land at a different height than you anticipated, make an agility saving throw. On a failure, fall prone.
You don't need a 10' run up.
