A small third Himinkryst caged in iron beneath the keel. It stays dark and cold until the ship starts to fall.
Ship Upgrade(Himinkryst) , Rare (No)
If every other flight source on the ship fails or runs dry, the reserve crystal wakes. For the next hour, the ship descends at 60 feet per round and takes no falling damage when it lands.
The reserve crystal then goes dark until it is recharged like any other Himinkryst.
