Your body is unusually flexible. This advantage comes in two levels:
Flexibility: You get +3 on Climbing rolls; on Escape rolls to get free of ropes, handcuffs, and similar restraints. You may ignore up to -3 in penalties for working in close quarters (including many Explosives and Mechanic rolls). 5 points
Double-Jointed: As above, but more so. You cannot stretch or squeeze yourself abnormally, but any part of your body may bend any way. You get +5 on Climbing, Escape rolls, and on attempts to break free. You may ignore up to -5 in penalties for close quarters. 15 points.
