Radiant
Weapons that have the radiant special property cause sensor-overloading blasts upon impact. When a radiant weapon hits a ship, that vessel’s crew members take a –2 penalty to gunnery checks and Piloting checks, as well as checks for the scan, target system, lock on, and improve countermeasures science officer actions. This penalty lasts until the end of the next gunnery phase, until an engineer succeeds at an Engineering check to stabilize the sensors during the engineering phase, or until a science officer succeeds at a Computers check to recalibrate the sensors during the helm phase. The DC for either check equals 10 + 1-1/2 × the tier of the starship that fired the radiant weapon.
