Default: DX-6.
This is the ability to perform gymnastic stunts, roll, take falls, etc. This can be handy on an adventure, as tightrope walking, human pyramids, and trapeze swinging all have useful applications. Each trick requires a separate skill roll, at whatever penalties the GM sees fit. If you are performing stunts on a moving vehicle or mount, roll against the lower of Acrobatics and the appropriate Driving or Riding skill.
You may substitute an Acrobatics roll for a DX roll in any attempt to jump, roll, avoid falling down, etc. As well, you may attempt an Acrobatic Dodge in combat – a jump or roll that avoids an attack in a flashy way. Finally, a successful Acrobatics roll will reduce the effective distance of any fall by five yards.
