Expedition Into Darkness Magic Book: Unlocking the Library

The magic book is one of the most sought-after items in Expedition Into Darkness, gated behind the Library Key. To obtain this key, players must complete the Lost Knowledge questline offered by the Scholar NPC in camp. This quest chain involves collecting specific items and delivering them to progress through the Scholar's reputation tiers.

The Scholar offers a multi-part quest chain. The first segment, Lost Knowledge I, requires three Empty Tomes. Completing this grants the Library Key and Scholar reputation. Lost Knowledge II demands additional crafting materials, offering another key as a reward.

Empty Tomes can be acquired through co-op play before officially accepting the quest. Farm these items in earlier raids so you can turn them in immediately upon unlocking the Scholar's questline.

Lost Knowledge Questline Breakdown

The Lost Knowledge questline is the primary gateway to the magic book. The Scholar acts as the quest giver, and the objectives scale in material complexity as you progress. Understanding the material requirements beforehand saves significant time.

Empty Tomes

  • Quest: Lost Knowledge I
  • Found in early raid zones
  • Tradeable via co-op partners
  • Required quantity: 3

Glass Vials & Carrots

  • Quest: Lost Knowledge II
  • Common crafting materials
  • Carrots found in provision areas
  • Required quantity: 2 Vials, Carrots

Vermillion

  • Quest: Lost Knowledge II
  • Rarer material component
  • Used in advanced Scholar turn-ins
  • Check vendor inventories

Once you have the required items, interact with the Scholar, select the corresponding quest, and hold the turn-in button. The Library Key will appear in your letters or inventory. Immediately navigate to your character screen and place the key on your key ring to prevent accidental loss or sale.

Inventory Management

The Library Key occupies valuable inventory space if left in your main backpack. Always transfer it to the key ring slot in your character menu. This prevents accidental selling when clearing loot at vendors.

Strings Attached: Catacomb Rope Quest Guide

The Strings Attached quest (also tracked as "No Strings Attached" in the task list) is a secondary quest that rewards useful items upon completion. The Squire provides this quest, which tasks you with re-fastening cut guide ropes in the Catacombs.

The quest description states that someone cut the guide ropes in the Catacombs. Your objective is to find the anchor points and inspect them. Contrary to what the quest implies, you do not need to carry ropes in your inventory. Simply inspect the designated anchor points.

Rope AnchorLocationNavigation RouteAction Required
Balcony RopeAtrium area, hanging from balconyFour Maidens Passage to Atrium, stay rightClimb up, select "Take Rope"
Crane RopeNear Masonry Annex entranceAtrium, adjacent to crane mechanismInspect and attach rope
1

Enter the Catacombs

Select the Catacombs map from your raid menu. The Masonry Annex is an alternate entry point, but starting from the main entrance provides clearer navigation for this quest.

2

Navigate to the Atrium

From the Four Maidens Passage, head through the opened door into the Atrium. Stay to the right side and eliminate any Fleshkin enemies along the way.

3

Find the Balcony Rope

Look for a rope hanging down from a balcony near a chest. Climb the rope, then look for the interaction bubble that says "Take Rope" (not just "Climb"). Taking the rope completes the first objective.

4

Locate the Crane Rope Anchor

Return to the Atrium area and find the crane mechanism near the Masonry Annex entrance. Inspect the anchor point to attach the rope and complete the quest objective.

5

Extract and Turn In

Head to the extraction point. Return to camp, speak with the Squire, and turn in the Strings Attached quest to receive your rewards.

Quest Completion

After completing both rope inspections, extract from the raid safely. Return to camp and speak with the Squire to hand in the quest. The reward includes bolts and miscellaneous useful items for progression.

Raid Navigation and Quest Tracking

Efficient quest completion in Expedition Into Darkness depends heavily on understanding the game's navigation and tracking systems. The Catacombs feature interconnected zones that can disorient unprepared players.

Press O during a raid to display your active tasks. This overlay shows all current quest objectives, including those specific to the zone you are in. However, the task list may display quests that cannot be completed in your current raid, which can cause confusion.

CisternWater area, lower accessLower Prison, AtriumAccessible via crane kick
Zone Awareness

The Masonry Annex rope anchor and the crane rope are in different locations. Many players confuse these two points. The crane rope is near the crane mechanism in the Atrium, while the Masonry Annex has its own separate anchor point.

Key navigation tips for Catacomb quests:

  • Always orient from the Four Maidens Passage as your central hub
  • The Atrium connects to both Strings Attached objective points
  • Watch for trap hammers and environmental hazards near chests
  • The Cistern can be accessed by kicking the crane mechanism, but serves as a detour for these quests
  • Extract through the standard extraction point after completing objectives

Combat and Loot Considerations

While questing in the Catacombs, you will encounter Fleshkin enemies and other threats. Balancing quest progression with combat readiness is essential for successful extraction.

The Catacombs feature a rich loot table, making it tempting to explore every room. However, for quest-focused runs, prioritize reaching objective locations quickly. Only loot items that directly contribute to your active quests or provide essential combat upgrades.

Enemy TypeThreat LevelRecommended StrategyCommon Location
Fleshkin WarriorsModerateStrong melee weapon, block patternsAtrium, Four Maidens
Goblin CaptainsHighRequired for Black Heart Menace questVarious Catacomb zones
Trap HazardsLow-ModerateEnvironmental awareness, avoid triggersNear chests, corridors
Loot Management

Quest-focused runs should minimize looting to reduce time in hostile zones. However, rare items like the Flamberge sword can significantly boost combat effectiveness. Weigh the risk of extended exposure against potential upgrades.

Pre-Raid Preparation Checklist:

  • Store Library Key on key ring before raiding
  • Check active quests with O key upon entering
  • Verify quest items are in inventory (Empty Tomes, Glass Vials)
  • Equip strong melee weapon for Fleshkin encounters
  • Clear inventory space for quest rewards and essential loot

Additional Quests and Future Content

Beyond the Library Key and Strings Attached quests, Expedition Into Darkness features several other notable quests in the Catacombs that players should be aware of. These quests offer additional rewards and progression opportunities.

The Nine Lives quest requires filling water bowls in three locations: the Lower Prison, the Stone Masonry, and near the Leaflet Post. This quest is notably challenging due to the difficulty in locating all three water bowl positions, particularly the one near the Leaflet Post.

The Black Heart Menace II quest requires defeating a Goblin Captain, which only appears in specific Catacomb zones. Ensure you are in the correct map variant before attempting this objective, as Goblin Captains do not spawn in Fleshkin-dominated areas.

Quest Layering

Stack multiple quests targeting the same zone to maximize efficiency. For example, Strings Attached and Nine Lives both require Catacomb access. Plan your route to hit objectives for both quests in a single raid when possible.

Q: How do I get the Library Key for the magic book in Expedition Into Darkness?

Complete the Lost Knowledge I quest from the Scholar NPC in camp. You need to collect and hand over 3 Empty Tomes. Once turned in, the Library Key appears in your letters. Transfer it to your key ring immediately to preserve inventory space.

Q: Do I need to bring ropes for the Strings Attached quest?

No. Despite the quest description mentioning cut guide ropes, you only need to inspect the anchor points. At the balcony rope location, climb up and select 'Take Rope' from the interaction bubble. No rope items are required in your inventory.

Q: Where is the balcony rope in the Catacombs?

The balcony rope is in the Atrium area. Navigate from the Four Maidens Passage through the door into the Atrium, then stay to the right. Look for a rope hanging from a balcony near a chest. Climb it and select the 'Take Rope' option above the climb prompt.

Q: Can I complete Lost Knowledge II for another Library Key?

Yes. Lost Knowledge II requires 2 Glass Vials, Carrots, and Vermillion. Turning these in to the Scholar grants an additional Library Key, which can be useful if you lose your original or want a backup.

Q: How do I track quests during a raid?

Press O during a raid to display your active task overlay. This shows all current quest objectives. Note that some displayed quests may not be completable in your current map variant, so verify enemy types and zone requirements before proceeding.
