Reverb cascade torpedo builds can be massive fun although they are one hit wonders, once you've fired your torps that's it. If the target ship countered them (with PD or ECM) and his shields didn't drop, you've got to run.
My build alternates between two setups, one for hit and run and one for sustained combat.
Both builds have:
(All Mods grade 5)
-Prismatic shields (reinforced)
-Mix of heavy duty and resistance augmented shield boosters
-Reactive hull armour (heavy duty) with thermal resist HRPs and module reinforcements.
-2x a7 SCBS
-dirty drives
Hit and run hardpoints:
-2 medium and 1 small torpedo launchers (with reverb cascade effect)
-2 class 4 Multicannons, both overcharged (one incendiary, one corrosive)
-1 class 3 multicannon, Rapid fire with thermal shock effect
-1 small Rapid fire pulse laser with scramble spectrum effect.
Sustained combat build:
-2 medium Rapid fire pulses with phasing sequence effect
-2 small Rapid fire pulses with scramble spectrum effect
The rest is the same
I'm pretty new to PvP, but it seems a solid build and more importantly it's fun
+pulses are fixed, MCs are all gimballed.
