A little thought experiment (no, honest, I'm not building a stealth carrier/torpedo boat designed for exterminatus
) brought me up against this little conundrum: how do you determine the Crit Rating for an Atomic-rigged torpedo- does it wholly replace the standard warhead, or is it an "add-on" to an existing (while replacing the standard damage rules for torpedoes with atomics)? Does it get a Terminal Penetration value?
Range and speed are constant across torpedoes (aside from those with the Short Burn guidance package, obviously), so we can use those figures (Speed 10 VU/turn, Range 60 VU), but how do we determine the critical?
For that matter, would an atomic torpedo still do 1d5+4 hits? and would it still get to combine the damage from those hits or would the torpedo rules of "no combining damage in a salvo" apply?
All thoughts welcome
