Crypts are sieges: through a short crypt to an open valley, kindle the altar and hold out against the waves, then go through the gate that rises to the god. The first crypt has no god; its chest waits by the gate. A god's chest holds a weapon from the next tier up (the last god's, its own tier) and usually a treasure map to the next crypt's treasure isle. Siege waves drop nothing; winning the siege pays XP, and the loot is in the chest.
