The Codex

The Codex is the game's own record of what you have seen: four tabs, opened from the title.

Sets

Every one of the 22 sets as a card: its pieces as tiles, its three bonuses and its motto. A piece is a dark outline until you have seen it. A locked set shows a lock and its progress: "Locked. Win 20 battles wearing 2+ Warden pieces (7/20)". Below the sets, every synergy is listed from the start.

Uniques

The uniques, the treasures and their counts: "Uniques 4/30 found", "Treasures 1/6 carried out". An unfound unique reads "???" with its slot and depth and "Not yet found. Bosses, elites, chests and the merchant carry them." A treasure you have carried out reads "Carried out" and "Yours:" with its boon.

Beasts

The bestiary: every enemy in a niche, three to a row. One you have not met is a still silhouette and "???". Tap one you have met for its card: its kind, depth, lore and traits. A boss you have fought shows his whole fight instead: his numbers at his floor, "HIS TURNS", "HIS RULES" and "HOW TO BEAT HIM".

Runs: the Ledger of the Fallen

Your last 30 runs of any kind, newest first. Each card shows the hero's face in the gear the run ended in, that gear as tiles, and a line such as:

Wren floor 14 killed by Mother Brine, 34% of her health left

Other endings read "broke the curse", "turned back" and "cleared the Cellars". Tags mark a "daily" or "seeded" run and the Greed level. Under a death: the gold it left to the dragon. Above them all, the total: "Left to the dragon's hoard".

How things get revealed

• An item is revealed by being seen: in your bag, your stash, the market or a merchant's stock. You need not buy it.
• An enemy is revealed by being fought.
• Every kind of run reveals, Daily and seeded runs too.

The Codex travels with cloud save.
