Items

Opens the bedroom chest holding the Old Cavalry Saber.

Opens the dresser in the woman's bedroom, yielding the two Small Mirrors.

Opens Jeremy Hartwood's study on the 1st floor, and the stairs down to the caverns inside it.

Opens the locked door by the conservatory leading down to the cellar.

Opens the ballroom, once the walking corpse of the pirate is destroyed.

Opens the chest at the top of the caverns' plank bridge maze.

Empty when first found. Fill it with a Can of Oil and light it with the Matches or the Lighter before entering any artificially darkened room — the dark room, the library, and the final cavern all require it.

Pour into the Oil Lamp to refill it, then discard the empty can to save inventory space.

Lights the Oil Lamp for the first time.

A second flame source. Needed to relight the Oil Lamp in the final cavern before throwing it at the tree guardian.

The box itself does nothing — drink the flask inside for a flat health bonus (it adds to your current total rather than restoring a maximum), then drop the empty box and bottle to save space.

Drape it over the possessed painting of the mountain man in the 2nd floor art gallery to stop it from attacking.

Place one on each of the two small statues in the 3rd floor hallway to banish the nightgaunts guarding the stairs. Don't let the nightgaunts hit you first — a broken mirror is useless.

Throw it at the suit of armor on the 2nd floor landing to knock the Knight's Sword loose.

Empty at first. Use it on the water-filled barrel in the kitchen, then use the filled jug on the smoking room's ashtray to clear its toxic smoke.

Play the green-labeled record — Saint-Saëns' Danse Macabre — near the ballroom ghosts to draw them away from the fireplace mantle long enough to grab the Pirates' Key.

Trigger it against the indentation in the library's bookshelves to open the secret ritual chamber.

Place it before the tree guardian in the final cavern to seal off its fireball attacks long enough to finish it off.

Set it on the dining room table to pacify the five zombies seated there instead of fighting all of them at once.

Fits the fist-sized hole in the stone door at the end of the dark labyrinth, deeper in the caverns.

Opens the door back to an earlier section of the caverns — the only way out once the bridge to the mansion collapses.
