I changed the cobalt frigate and copied (then changed) these files over from the Kol:
WeaponType "Beam"
damageEnums
AttackType "CAPITALSHIP"
DamageAffectType "AFFECTS_SHIELDS_AND_HULL"
DamageApplyType "OVERTIME"
DamageType "ENERGY"
WeaponClassType "BEAM"
DamagePerBank:FRONT 280.000000
DamagePerBank:BACK 0.000000

beamCoreTextureName "TechCapitalBeam_Core"
beamWidth 35.000000
beamGlowColor ffffffff
beamCoreColor ffffffff
beamTilingRate 3.000000
then I changed the sounds to 3, and changed them to the cobalt laser firing sounds. I also changed the beam width to 10 and beam duration to 0.1. The burst count, as mentioned, was channged to 4 (and of course I really lowered the damage

)
Thanks in advance for the help!
