Steady Balance
Steady Balance Level 1
General Skill
Prerequisites: trained in Acrobatics
You can keep your balance easily, even in adverse conditions. Whenever you roll a success using the Balance action, you get a critical success instead. You're not Flat-Footed while attempting to Balance on narrow surfaces and uneven ground. Thanks to your incredible balance, you can attempt an Acrobatics check instead of a Reflex save to Grab An Edge.
