BDH: Ship Advancement
Like characters, the ship earns experience that can be spent on advancements. Ships earn 1 xp per episode. Players are also 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.
Tier 0
Tier 0 changes (swapping features with no xp cost during or after the first episode) will be considered on a case by case basis and require consensus from the group, but as a general rule the ship is the ship.
