I am thinking about setting up my ship with... the Enhanced Plasma Manifold from the Oberth.
I know the Exocomp gives a bonus to the Red Matter, but what about the other ones? Does anyone know for sure?
I haven't tested it and can provide no numbers, but when you have the EPM equipped, the tool tip display shows bonuses provided by the exocomp. That could be a bug, but really odd for a bug to display that much formatted text if it is; those bonuses do not appear on the tool tip for the Subspace Modulator (that I recall,) and I don't have a RMC to check.
One caveat, though. The EPM puts all other batteries on cooldown, so it's best on an escort or another ship with limited device options.
