The XV-99's minifab system added an enormous amount of utility to Ves, yet it did not come without a price. It was the most vulnerable component to the XV-99 and could easily break from sustaining a direct impact or a moderate shock.
Due to how much space its components took up, the minifab system could only be mounted on the back of the armor, taking up space that should have been occupied by a modular backpack of his choice.
However, due to the high level of integration and structural strengthening around the minifab system, it could take a lot more impacts and shocks than if it turned into a fully modular system. Right now, Ves still possessed the possibility of taking off the minifab system in the field, but only if he removed his combat armor and disassembled the rear portion with tools.
