Follow this detailed walkthrough for Lords of the Fallen's Keystone Monastery, covering enemy strategies for Infected and Marauders, item locations, and key objectives.

Walkthrough
  1. 1
    As soon as you gain control of Harkyn, follow the on-screen instructions to complete the combat training by killing the enemy in front of you.
  2. 2
    Head up the stairs and talk to Kaslo.
  3. 3
    After the conversation, look to the left of the top of the stairs for an Audio Note (Infested II: The Guard). Collecting your first Audio Note earns the achievement/trophy 'Bookworm'.
  4. 4
    Return down the stairs and open the door to the right.
  5. 5
    Defeat the Infected enemy directly in front of you.
  6. 6
    Practice your weapon and shield combination to take out the Infected guard.
  7. 7
    Move down the hallway to the right. As you reach the corner, put your shield up as there is another Infected just to the right around the corner.
  8. 8
    Go down the short set of stairs here and eliminate the pair of Infected, trying to attack them one at a time.
  9. 9
    Look along the left-hand wall for a pair of bookcases. Destroy these to reveal a half-open gate behind them. Run at the gate and roll beneath it to find a chest inside. Open it for an Empty Bottle (adds an additional potion slot).
  10. 10
    Return up the stairs and ignore the opening to your left for now. Follow the walkway all the way to the end and kill the Infected here.
  11. 11
    Acquire another Audio Note (Infested I: The Sick).
  12. 12
    Head back to the opening near the top of the stairs and go through the corridor.
  13. 13
    Kill the Infected at the far end and go down the stairs.
  14. 14
    Approach the red shard (the Giant Key) at the end of the short hallway. The corpses on the ground will come to life and attack. Defeat both of them and grab the Giant Key.
  15. 15
    Back up the stairs, grab the Audio Note (The Rhogar II: Monk Notes) ahead.
  16. 16
    Continue around the corner and kill the Infected here. Note the Loot Crystal #1 here (currently inactive, will activate after killing the associated boss).
  17. 17
    Climb the stairs opposite the Loot Crystal to find a Marauder at the top.
  18. 18
    Lure the Marauder back down the stairs to the room with Loot Crystal #1 to have more space to maneuver and kill him.
  19. 19
    After killing the Marauder, climb the stairs and at the top, you'll find an Energy Shard.
  20. 20
    Drop down from the broken railing to the floor below.
  21. 21
    Speak to Kaslo. During the conversation, choose the “Support Me” option to have him refill your potions.
  22. 22
    After the chat, open the door behind him for a cut-scene.

New Game + Notes:

  • An Audio Note (Greater Powers: Judge Assassin) can be found in the nearby corner after destroying the bookcases.
  • An Audio Note (Greater Powers: Judge Cleric) can be found in the small niche to the left of the statue after killing the Marauder.

New Enemy: Infected

  • Attacks: Melee Swings (varying combos depending on weapon), Overhead Slam, Screech (AoE stun), Bite (health drain grab).
  • Combat Strategy: Fairly weak but fast. Learn their weapon-specific move-sets. They are vulnerable to fire magic. Some may feign death or revive after being downed until the XP notification appears.

New Enemy: Marauder

  • Attacks: Melee Swings (2-hit combo), Overhead Slam (damaging, causes knockback), Stab Attack (single swing).
  • Combat Strategy: Moves are well-telegraphed. Be patient, lure attacks, and strike once or twice during recovery windows. The overhead slam offers the largest attack window.

Collectibles:

  • Audio Note (Infested II: The Guard) — Near Kaslo after initial training.
  • Empty Bottle — In a chest behind destructible bookcases.
  • Audio Note (Infested I: The Sick) — At the end of the walkway past the first set of stairs.
  • Giant Key — At the end of a short hallway after descending stairs, guarded by reviving corpses.
  • Audio Note (The Rhogar II: Monk Notes) — After grabbing the Giant Key and climbing stairs.
  • Loot Crystal #1 — In the room where the Marauder is lured.
  • Energy Shard — At the top of the stairs after killing the Marauder.
