ECM Modules

Electronic countermeasure (ECM) modules are a type of powerful instrument designed to foil an enemy starship’s sensors, impair a starship’s systems, and in some cases alter the battlefield itself. ECM modules must be installed on weapon mounts, but they are activated by a science officer during the gunnery phase. ECM modules follow the same rules for range and quadrant targeting as conventional starship weapons.
When activating an ECM module, a science officer attempts a special gunnery check, adding their ranks in the Computers skill but adding neither their base attack bonus nor their ranks in the Piloting skill, and adding their Intelligence modifier in place of their Dexterity modifier; an NPC officer typically has a gunnery modifier equal to that of the gunner’s gunnery modifier. Compare the result of this gunnery check to the target’s Target Lock (TL). If the result equals or exceeds the target’s TL, the science officer hits and applies the ECM module’s effects. Due to the interference created by shields, starships with functioning shields in the targeted quadrant gain a +2 circumstance bonus to their TL against ECM modules. ECM modules do not deal critical damage.


Gravity Well

A gravity well module—which includes gravity generators, gravity well generators, and interdiction arrays—manipulates gravitational forces around the targeted starship, slowing the starship considerably. Until the end of the next piloting phase, the target’s speed is halved, and its maneuverability becomes one step worse (to at worst clumsy maneuverability). A gravity well module requires tremendous energy to operate; it cannot be activated unless an engineer succeeds at a divert crew action to divert power to the weapons that round.
