Deep in the Barren Swamp, you might find an NPC named the Owl Doctor in Lies of P that you can talk to and even beat in an intense optional boss fight. An individual broken by cruel experiments from the Alchemist, this figure hides in the lower floors of a wooden shack you can reach by climbing down a ladder. This quick and brutal opponent has deceptive attacks that can be hard to predict in the limited space of this boss battle.
