And multipliers... maybe each warhead would halve the cloak level of the mine instead?
Come to think of it, remember how in Stars, cargo mass affected things like cloaking and fuel consumption? That is, a 100kT ship carrying 100kT of cargo would have half the cloaking ability and double the fuel consumption of the same ship running empty. (Actually Stars! used some funky cloak-per-kT vs. something or other chart to determine the visibility radius... oh yes, cloaking will be radius based, won't it?

)
