Dual Augmentation
Source
Tech Revolution pg. 33
If you have an augmentation that functions as a weapon, such as a bone blade or optical laser, you can install an additional augmentation in the same system. You can have no more than two augmentations in that system, even if you have another ability that provides you a similar benefit.
