Forgive me for asking this question because I haven't had my coffee do you mean a build using the Crystalline Entity Torp or to fight the Entity itself?
Im looking for an equipment list to use in the crystalline entity event, i know my engineering slots will use anti kinetic, but what would be the rest of the equipment.
Also, for what it is worth here is my Fleet T6 Malem build. It's still a work in progress but I enjoy it and I'm pretty survivable. RCS console is a hold over my days of flying a Tulwar or a Dyson. I need to replace it. I might pick up the Terran Advanced Disruptor Array and replace the experimental proton array though I'm not sure if I want lose the boost to the photon torpedoes.
Normally i would say if you want to do a torp build go for a sci ship because it synergises quite well with torp builds but as a romulan your options are rather limited. I have never made a torp build so i cant give much advice from my experience but i would recommend flying a ship which can use gravity well, every bit of kinetic damage helps.
It doesnt need to have an enhanced cloaking device, ships that cant fire while cloaked are just as effective if not more so as the shields will help protect you during the explosions from the entity.
