A couple of things. If the crew rebels/ is captured, they will not go into withdrawl, they will stop being Dominion (or whatever) and start being Abbidon (or whomever their new empire is). That means that they will lose all of their old empire's traits and take on all of their new empire's traits (with the exception of atmosphere). So they would lose the to-hit penalty.

Hm. So you're right. While a frustration to my evil plans to intorduce the racial trait of Addiction, how about this... Give the racial trait access to a special subset of "druggy crew quarters" with the large penalty. Then restrict them from using the normal crew quarters (as per P&N normal, nomad and pirate traits). This way they must build ships with a drug dependent crew. Then give them the drug synth lab components as per my Last post.
Now when their ships are taken over the crew will remain drug dependent even though their racial traits have changed.
Alternatively you could give them a new set of ships and exclude them from using the normal shipset.

Aside: do they become "Abbidon" in terms of racial characteristics, or do they take on a neutral set of racial traits?

Also, I didn't see anything that granted immunity (even partial) from crew insurrection/(psy converter thingy I can't remember the name of).

True. I mis-spoke in my attempt to be metaphorical . It isn't so much that they would be immune to capture/insurrection, but that when they do fall prey to it, the captured ships will be seriously hobbled in combat because of the penalties for drug withdrawl. As such they won't pose as serious a threat to their parental race.

Now, would this work?
