InClair Obscur: Expedition 33, there are a lot of random key items you may find on your journey to take down the Paintress, but you might not have an idea of how they’re meant to be used or where to use these items. For example, in the early portion of the game, you can get an item called anOld Key, and if you look in the description, it says that it’s used to open anOld Door.

We’re going to walk players throughhow to get their hands on theOld Keyand where it’s meant to be used inClair Obscur: Expedition 33.

She will give you theOld Keyin exchange for aFestival Token,which is used for an old door, but Colette won’t tell you where the door is located.

You can get aFestival Tokenby defeating Maelle at the dock. You can get a third by speaking to Antoine and answering his three questions correctly. The answers are…67, zero, and abilities you internalize.

Once you get to this area, travel until you reach theLeft Street Rest Point flag. From the flag, head forward on the path, then head towards the right, past the giant sword stuck in the ground. Go through the broken doorway and immediately head towards the right to find a structure jutting out that you can walk across.

You’ll see a glowing item on top: aPolished Chroma Catalyst.However, if you drop into the structure via the hole, you canfind a locked old door thatrequires theOld Keyto open.
