READING THE ARCHIVE

One card. Every level.

Repeated effects apply once per level unless a card lists a different value for each level. Choosing an emergency ability replaces the one currently equipped. Structure upgrades appear in Builder Mode and Freemode; Builder-only artifacts are marked separately. Random endless-mode bosses do not award a Boss Cache. Scroll to the bottom for the complete hostile monster index.
