You have a penalty on tasks that require a firm grip. Each level (maxi-mum three levels) gives -2 with such tasks. This penalty is overall – not per hand. Affected tasks include melee weapon use, climbing, catching things, and anything else the GM deems requires a firm grip (e.g., an Acrobatics roll to catch a trapeze).
This disadvantage is mutually exclusive with No Fine Manipulators(p. 145).
