Enemies Encountered: Flea Armor, Lesser Demon, Mudman.

From the library card room, exit right. Access the platform above using a double jump.

If entering from the Library entrance, defeat three Dhurons, proceed upwards past Ectoplasms and spellbooks, then past Dhurons again, descend a large staircase, and use a double jump to reach the middle path where Corpsewood is located.

Enter the next room, which is small and empty, followed by a save room.

In the subsequent room, prepare for Flea Armor enemies that bounce off walls. Defeat them before engaging Dhurons.

Proceed to the next large room, which is heavily populated with Flea Armor. Engage them one at a time.

Clear the top part of this room first. In a room to the top right, interact with a candle flame on a table to obtain a Stone Mask.

Walk right towards a bookshelf, continue right until it moves, revealing a secret room containing a topaz circlet and a Holy Rod. The topaz circlet heals poison-based attacks.

Return to the main room and explore the bottom section.

Prepare for the Lesser Demon boss fight.

During the Lesser Demon fight, he will summon various enemies, including Mudman. Defeat a few Mudman to complete your monster list for a 'Master File'. The Lesser Demon is invulnerable while summoning enemies. Attack him when he stops summoning. He may also walk on the ground and punch.

After defeating the Lesser Demon, proceed left to a dead-end. Break pots to find Takemitsu, Onyx, and Frankfurter.

Encounter a barricade marked 'Mist could pass'. Transform into Mist (using the Form of Mist ability) by jumping next to it and pressing L1, then holding the right directional button to pass through. This leads to the Soul of Bat relic, allowing flight.

Backtrack to the save room before the Library section, then return to the Corpseweed area.

Transform into the Bat and fly to the platform above. In the room to the left, collect an antivenom, potion, and the FAERIE CARD relic, which acts as a Familiar that can heal and reveal secrets. Familiars are turned off by default and must be manually activated.

To fill in map holes, transform into the Bat and fly to the ceiling in the two squares located above the nearby Dhurons to discover them.

Exit the Library.
