Sometimes messing around the cargo bay with your gear yields better options.

Prerequisites: Engineering 5 ranks.

Benefit: choose a weapon or an armor. You can spend 1/5 the items cost and spend a day working on it. If you do, the item gains a +1 circumstances bonus to attack rolls, damage rolls, EAC, or KAC. You can perform this check multiple times on the same item, but you must choose a different thing to give a circumstance bonus too.
