Get rid of most of the cross-department cooperation (still have it a bit), and require the sacrifice of a living person to revive one. Since normal crew can't kill people without them being traitors, etc. it'll make it pretty hard to utilize. That and the heavy cost should make it rare but viable. You could also add some horrible secondary consequence like sometimes summoning people as zombies or them becoming immortal.
