|| Opens one Crimson Chest
The Crimson Key is crafted from Hardmode materials. It is used to unlock the Crimson Chest found in the Dungeon.
- Do not keep more than one of the same key on a world before opening the chest! When the key is used, it is consumed. If there are any of the same keys on the world, they will be consumed as well; even if they are not on your character. Once a chest is opened, additional keys may be found and will not disappear. They will however need to be used on a different world.
- Because of said consumption glitch, it is best not to craft the keys until you wish to use one and leave the other key molds you happen to have uncrafted.
