Building around Staff Acrobat

When you High Jump, Leap, or Long Jump while wielding your staff, you gain a +2 circumstance bonus to any Athletics check required and add 5 feet to the distance you can Leap vertically and horizontally. You can Shove and Trip even if you don’t have a free hand, provided you are wielding your staff. Finally, when you roll a success on a check to Balance while wielding your staff, you get a critical success instead.

• Is Assurance (Athletics) worth it?
• Giving a staff, bo staff, halfling sling staff, or any weapon in the spear or polearm group the Shove and Trip feats seems useful.
• What class? Swashbuckler, Monk, or Magus seem like natural fits
• Levering Strike provides a penalty to DCs against Shove, Trip, and Tumble Through (Swashbuckler!)
• Whirlwind Stance effectively gives you a shield and a free "Raise a Shield" action.
  • Bo Staff or War Lance
• Bullying Staff replaces the need for Titan Wrestler.
