Ready Weapon System (Open)
You carefully perform comprehensive pre-firing preparations for one weapon, reading each minute detail of its systems and giving the ship’s computers time to calculate the peak moment to fire the weapon so it can deal the maximum amount of damage to your opponents’ ship. While normally no one has the time or capacity to perform these tasks in the heat of battle, you know they can be invaluable when focused on properly. Select one weapon system when you perform this task. If that weapon is not fired this round but is fired on the next round after you have readied it, it deals +1 damage on a successful attack (+2 damage for starships of tier 6 and greater).
