Rigged secondary
1 charge. Change 1 missile, torpedo or cannon upgrade slot to a missile, torpedo or cannon upgrade slot. New slot cannot be the same as the slot it replaced. When an upgrade which uses the slot is used but after the attack is resolved, roll 1 attack die. On a focus result remove one charge from this card. If this card has 0 charges remaining the weapon can no longer be used.
A bit wordy, but it expands the customizability of some ships.
