If it is not too late (and ONLY if you are already tinkering) I had a few thoughts about the Tholian Energy web.
We know from Trek Cannon data the the tholians vastly preffered smaller, easier, faster to construct ships and outfited them with the dreaded 'Tholian Web' one of the most fearsome ship to ship weapons in Trek. A number of these small ships outfitted with the Web were easily the match for even large Alpha Quadrant ships. Anyways I was thinking of a rather devious late tech weapon that could only be mounted on *smaller* sized Tholian vessels. It could be something along the lines of 4X or 8X dmg to sheilds, something relatively balanced that would go on the little Tholian Ships, and possible a mount to reduce sizes for all components for small tholian ships (again a late tech discovery like after dreadnought, etc?)
You are a work horse Atrocities, and we all appreciate it sooo much
Look forward to crossing horns with you in the PBW game
