Quarterstaff Weapon Skill: Vault Image
Prerequisite: Proficiency with quarterstaves.
 

You can use your quarterstaff to help you leap long distances. You can use an action to double the length of your long jump, allowing you to leap a number of feet up to twice your Strength score (this jump is part of your movement). If you land adjacent to a creature at the end of this jump, you can make a single attack with your quarterstaff as part of this action.
