Erratic Debris

Erratic Debris is an 'area' effect that affects an entire gravity well, namely those that contain Asteroid Belts.
The effect of this ability is simple - it decreases the accuracy of all ships with weapons within the gravity well by 20%. It is unclear as to whether this merely decreases the damage output by 20%, or if 20% of all forms of ordinance miss.
Seemingly, only the Akkan's Targeting Uplink ability counters the effects of Erratic Debris, meaning a fleet supported with an Akkan class in an asteroid field is quite a bit more formidable than might appear.
