Secret walls, the Pandora Blade and the Witch's Grimoire

Secret walls open with the interact button (E on keyboard); the crosshair changes when you look at one. Skeletons often point straight at them, and walls without the usual brazier are worth checking. Players count 89 secret doors for Concealed Passages, the third-rarest achievement at 1.9%.

Pandora Blade

The Pandora Blade is behind a secret wall in the Crypt, near the chamber with the Endu Shrine Gate Key; that wall has no brazier. You can take it before the Shrine Guardian. It does not evolve, and it keeps levelling past 10. Patch 1.01.04 made its door count for Concealed Passages and added a hint. Full stats are in the weapon list.

Concealed Passages

The Mask of Second Sight and the marking charms highlight most secret doors, but some count even though nothing is behind them, and those are not highlighted. Players stuck at 88 found the last one in:

• the library stairs room in Siraatsu Castle;
• the Ancient World near the castle entrance;
• the Ancient World building that holds the Shock Rifle.

A secret door in the witch’s toilet is reported not to count.

Chests, treasures and Star Lizards

Emptied Coffers needs every chest, including Mimics, which disguise themselves as chests; the first is at the foot of the central tower on the Isle of Neasied. If you killed a Mimic without opening it, rest to respawn it. Glimmering Treasures needs every Treasure item; Star Lizards flee and drop loot sacks, so kill each one you see. Many food platters and silver skulls are behind secret walls too.

Witch’s Grimoire

The Witch’s Grimoire is near the starting beach. Inscribing any code unlocks Witchcraft (12.2% of players). Codes come from outside the game and unlock equipment or challenge modifiers; the code BLINGE gives the Ring of Fire. Grimoire equipment does not count toward weapon or accessory achievements. The author of a popular Steam guide suggests using a separate save before entering codes.
