Overview
The title seems kinda stupid, but it’s true. This is a Bone Charm the Heart CAN find, before finishing “The Royal Physician” mission while at the Hound Pits. However, it is in a locked area. This guide will tell you how to get it, if you can’t find the key yourself.
Cecelia: she actually becomes useful
Before I tell you where the locked door is, it would only make sense if I tell you where the key is. The first thing you need to do is talk to Cecelia, who should be in the bar right next to the door facing the river. She’ll talk to you about an abandoned apartment nearby, which if you have beaten the game already, you probably know what she is talking about, because it is the first building you go through after the Flooded District.
She will tell you that the key is under her bunk upstairs. Just simply go upstairs to the bunk beds outside the upstairs bathroom. Just look under the bunks until you find the key.
Unlock the door
After you get the key, go to the street outside the pub and go up the stairs at the street corner. There should be a partially broken staircase nearby, leading to the locked door. Go up the stairs, and unlock the door. The Bone Charm should be under the bed inside. There is some other stuff you can loot, including a cameo resting on a shelf near the door and an Elixir in the same room as the Bone Charm.
Pretty simple, right?
I hope this guide helps you out on your “quest for revenge” or whatnot. If it did not, however, post in the comments what went wrong, or if there was any variation as to how you found it. For example, if she gave you a different key location.
