Puzzles

Puzzles

Every vault worth having sits behind a puzzle. Each puzzle can be solved from what is in the room, and its answer is randomised per ruin from the world seed, so no two temples share a solution. Puzzle blocks — locks, clues, doors, plates, pylons, conduits, readers and sockets — cannot be broken in survival.

Solving opens what is nearby

When a lock is solved it opens every Sealed Door and unseals every sealed Vault Cache within 8 blocks sideways and 4 blocks up or down of it. A sealed vault tells you so when you try to claim it.

The six puzzle types

Puzzle	Clue in the room	What you do
Ballast Plates	Each plate shows 1–8 lights	Put exactly that many items on every plate near the vault, then claim. Too many or too few keeps it sealed.
Glyph sequence	Four glyphs carved on the wall	Open the Glyph Lock keypad and enter the four glyphs, read left to right as you face the wall. A wrong entry resets the lock for a few seconds.
Conduit routing	Conduit pieces on the floor, a Conduit Source and a Conduit Lock	Use pieces to turn them until power flows from the source to the lock. Pieces light up as power reaches them.
Resonance tuning	A Tuning Crystal shows the target colour	Use each Resonance Pylon to step through its eight pitches until every pylon matches. Each pylon plays its note.
Keycards	A Card Reader shows its tier as lit bars	Use the reader holding a Survey (tier 1), Security (tier 2) or Command (tier 3) Keycard. A higher tier opens a lower-tier reader. The card is never taken.
Relic socket	The socket names the relic it wants	Use it holding that chapter's relic. The socket reads the relic and gives it back.

Keycards come from the ruins themselves — usually a chest found before the reader — and from tier-3 loot. They cannot be sold through NeroEconomy.

Vault modes

Server operators choose how vaults are shared with vaults.mode (Configuration):

Mode	Behaviour
per_player (default)	Every player can claim each vault once, with their own roll.
first_come	The first claim takes the vault. When a puzzle unseals a vault, the solver's roll is reserved, so someone waiting beside the vault cannot take it. Others are told the vault was opened first.
timed(hours)	Each player can claim again after the given number of hours, e.g. timed(24).
