Firefly Prime: Ship Advancement
Like characters, the ship earns experience that can be spent on advancements. Ships earn 1 xp per episode. Players are permitted to donate character experience to ship advancement spends.
Ship advancement may require more fictional support than character advancement due to the labor and materials required to justify improvements.
