Karla is located in the locked cell at the bottom of the Irithyll Dungeon that requires the Jailer’s Key Ring . This is located by making your way through Irithyll Dungeon to the roof of the church in the toxic swamp of the Profaned Capital.

Once freed she’ll move to Firelink Shrine, located in the alcove under Andre the Blacksmith. She accepts dark tomes, basically anything the other NPCs won’t accept, and will expand her inventory for each that she accepts.

Drops:

• 1,000 Souls
• Karla’s Armor Set and Karla’s Ashes
