Unsupported ST

#limitation
Limitation: -25%

You have increased strength through gengineering or biomods, but the gengineers did a shoddy job of muscle attachment or you haven't bothered to build up your bone mass to support the additional strength. You may take this limitation on some or all of any ST, Lifting ST, or Striking ST increase of +3 or more that's due to biomods or gengineering. Keep track of your fully supported ST and the higher “unsupported” ST. Use the unsupported ST score to determine Basic Lift for purposes of sustained carrying.

However, for any transitory feat of strength - including lifting, jumping, grappling, throwing, or attacking - you can choose to use either the safe, supported ST score, or your unsupported ST. No roll is required to use the unsupported strength, but in the next second, roll vs. HT. Success means no problem occurs, but a failure causes 1 point of injury; critical failure, or two failures in consecutive seconds, does 1d injury and causes any one limb you are using to be crippled.
