A Blood Key is an item that can be obtained in the Catacombs.
A Blood Key can used to open a Blood Door in the Catacombs, which leads to the Blood Room where 
The Watcher can be fought. The Blood Key is dropped by either a miniboss, such as the 
Lost Adventurer or 
Angry Archaeologist, or when all Mobs with a star have been slain.
Clicking a Blood Door with the Blood Key consumes the Blood Key and opens the door. The Blood Key is usable by any person within the dungeon, regardless of whether or not they are the player who obtained it.
Trivia[]
