Trying to level up a weak sword, club, or spear in Queen's Domain? There's a repeatable weapon XP farming spot in the Tower of Knowledge where you can fight large groups of Book Bugs, gain weapon levels, and collect useful loot without traveling far between encounters.
The trick is to deliberately trigger the wrong gargoyles at a numbered puzzle. These encounters produce Book Bugs, which can be defeated in groups before returning to a nearby Crystal Monument to reset the enemies.
This guide explains exactly where to find the farm, how to trigger the Book Bugs, how to repeat the loop, and which alternative locations are worth trying if your weapon struggles against them.

Quick Answer: How to Farm Weapon XP Fast
The Tower of Knowledge gargoyle puzzle is a useful early-to-mid-game weapon XP farming location in Queen's Domain.
Here's the basic method:
- Travel to the Tower of Knowledge using its unlocked teleporter.
- Follow the interior route to the nearby Crystal Monument.
- Save and rest, then head down to the outdoor gargoyle puzzle.
- Shoot an incorrect gargoyle to trigger enemies and Book Bug spawns.
- Defeat the Book Bugs with the weapon you want to level.
- Collect the dropped items.
- Return to the Crystal Monument, save and rest, and repeat.
How much can you gain? Around 1–2 weapon levels per run is possible with this farming method, particularly when leveling lower-level weapons. Results vary depending on your weapon, current level, and the number of enemies defeated.
The main advantage is the combination of a large enemy group and a nearby reset point.
Where to Find the Weapon XP Farm in Queen's Domain
The farming spot is located in the Tower of Knowledge, at the outdoor walkway containing the numbered gargoyle puzzle.
You can recognize the area by several landmarks:
- A stone walkway bordered by tall iron railings.
- Gargoyle statues mounted on pillars along the fence.
- A greenish sky visible beyond the railing.
- An arched doorway leading back into the tower.
- Bookshelves and scattered books near the courtyard.
The gargoyles are part of a puzzle, but choosing the wrong statues can trigger enemy encounters.
Normally, you would avoid these incorrect activations while solving the puzzle. For weapon XP farming, however, they're exactly what you want.
The encounters can produce Gargoyle Warriors, Gargoyle Arbelists, and groups of Book Bugs.
Book Bugs are especially useful because several can appear together, allowing you to attack multiple enemies in a relatively small area.
When Can You Access This Farm?
You must first reach the Tower of Knowledge and gain access to its gargoyle puzzle area.
The route is particularly convenient after unlocking the tower's Zone 3 teleporter and the nearby Crystal Monument.
This is not an immediate starting-area farm. If you haven't reached the Tower of Knowledge yet, continue progressing through the game until you can access the puzzle.
Once the area is available, you can return to it whenever you want to test the farming loop.
How to Reach the Tower of Knowledge Gargoyle Puzzle
If you've already visited the gargoyle puzzle, you can return using the Tower of Knowledge teleporter.
Step 1: Teleport to the Tower of Knowledge
Open the teleport menu and select Tower of Knowledge.
After arriving, move across the circular chamber with the green-patterned floor and head toward the doorway in the surrounding stone wall.
Continue through the doorway into the tower's interior corridor.
Step 2: Use the Elevator
Follow the corridor until you reach the elevator mechanism.
Look for the wall-mounted lever beside the elevator entrance.
Activate the lever and use the elevator to reach the upper section of the tower.
Once you leave the elevator, continue along the wooden walkway and toward the interior stairwell.
Step 3: Find the Crystal Monument
Follow the upper walkway until you reach the Crystal Monument, recognizable by the glowing blue crystal above its decorated stone pedestal.
This is the most important landmark for the farming method.
Use the monument to save and rest before beginning the loop.
The nearby reset point means you won't need to travel across the entire tower after every farming run.
Step 4: Head Down to the Gargoyle Puzzle
From the Crystal Monument, return toward the lower section containing the gargoyle puzzle.
Follow the interior route to the outdoor stone walkway.
Look for the iron fence and several gargoyle statues attached to pillars along its edge.
You'll also notice bookshelves, scattered books, and an arched entrance connecting the courtyard to the interior.
You've reached the farming area.
How to Spawn Book Bugs and Farm Weapon XP
The farming method involves deliberately triggering enemy encounters by attacking the wrong gargoyles.
Follow these steps to get started.
Step 1: Equip the Weapon You Want to Level
Before activating the gargoyles, equip the weapon you want to improve.
This method is particularly useful when you've picked up a weapon that is noticeably weaker than your main equipment.
You can try leveling swords, clubs, spears, and other weapons here, although some damage types may clear Book Bugs more efficiently than others.
If your weapon has a wide attack animation, that can help when several Book Bugs gather together.
Step 2: Shoot an Incorrect Gargoyle
Approach the gargoyle statues along the iron fence.
Aim at one of the incorrect gargoyles rather than following the puzzle's intended solution.
Shoot the statue to activate the encounter.
Depending on the gargoyle, you may see enemies such as:
- Gargoyle Warrior
- Gargoyle Arbelist
These are hostile enemies, so prepare to move as soon as the encounter begins.
You can identify them by their enemy names and health bars.
Step 3: Trigger the Book Bug Group
Continue using the incorrect gargoyle encounters to produce Book Bug spawns.
Book Bugs look like animated books with small legs. They move around the courtyard, bookshelves, and nearby doorway.
The advantage of this location is the number of Book Bugs that can appear within a relatively small area.
You don't need to chase enemies through several rooms to find another group.
Instead, focus on gathering and defeating the Book Bugs around the puzzle area.
Step 4: Defeat the Book Bugs Efficiently
Once the Book Bugs have appeared, use attacks that can strike multiple nearby enemies.
Wide melee swings and area-of-effect attacks are particularly convenient when the creatures gather in groups.
Try not to let too many enemies surround you.
If Gargoyle Warriors or Gargoyle Arbelists are still attacking, deal with the immediate danger before continuing the farm.
The arched doorway leading back inside can provide space to retreat and manage enemies in smaller groups.
Tip: The goal is to earn weapon experience consistently, not to trigger every possible enemy at once. A controlled farming run is often easier to repeat than a chaotic fight.
Step 5: Collect the Loot
After defeating the Book Bugs, check the floor for dropped items.
You may find glowing loot piles scattered around the courtyard and near the interior doorway.
Book Bugs can provide useful materials, including Freshly Dried Herbs.
Other enemies in the area may drop additional items.
Collect what you need before returning to the Crystal Monument.
You'll also gain experience from defeating enemies, making this a useful location for improving your weapon while progressing your character.
How to Reset the Book Bug Farm and Repeat
The main reason this farming spot is useful is that the enemy encounters can be repeated using the nearby Crystal Monument.
Once you've completed a run, follow this loop.
Step 1: Finish the Encounter
Defeat the Book Bugs and deal with any gargoyle enemies that are still threatening you.
Avoid leaving dangerous enemies directly behind you while returning to the interior.
Step 2: Collect Your Drops
Check the courtyard and doorway for remaining loot.
Pick up useful items before resetting the enemies.
Step 3: Return to the Crystal Monument
Head back inside the tower and follow the short return route to the glowing blue Crystal Monument.
You don't need to teleport to another region.
Step 4: Save and Rest
Interact with the Crystal Monument.
Use the available save and rest functions to preserve your progress and reset the enemies.
Resting is what allows the nearby enemy encounters to return.
Saving your progress periodically is also recommended, especially after gaining several weapon levels.
Step 5: Return to the Gargoyles
Head back down to the outdoor gargoyle puzzle.
Attack an incorrect gargoyle again to trigger another encounter.
Defeat the Book Bugs, collect the drops, and return to the Crystal Monument.
Step 6: Repeat as Needed
Continue the farming loop until you've gained the weapon levels you're aiming for.
The process is simple:
Crystal Monument → Incorrect Gargoyle → Book Bugs → Collect Loot → Crystal Monument → Repeat
The repeated encounter makes this location particularly convenient when you want to level several weapons without searching for new enemy groups each time.
How Much Weapon XP Can You Earn Per Run?
The Tower of Knowledge Book Bug farm can provide noticeable weapon progression, especially when you're working on a lower-level weapon.
A productive run can yield approximately one or two weapon levels, although that should be treated as an example rather than a guaranteed reward.
Your results may vary for several reasons.
Weapon Level
A weapon that has barely been upgraded may level faster than one that's already significantly developed.
As you continue leveling, you may need more encounters to gain another level.
Number of Enemies Defeated
The Book Bug method is useful because several enemies can appear together.
Defeating a larger group provides more opportunities to gain experience than fighting a single enemy.
However, triggering too many enemies at once can make the encounter harder to control.
Weapon Damage Type
Some enemies resist particular types of damage.
If your weapon deals relatively little damage to Book Bugs, each farming run may take longer.
That doesn't necessarily make the location unusable, but another enemy group could be more efficient.
Farming Speed
The best farming method isn't always the one that produces the largest number of enemies.
It's the one you can complete quickly and consistently.
Once you've learned the route between the Crystal Monument and the gargoyle puzzle, the time spent traveling between runs becomes much shorter.
Tip: If you're gaining weapon levels consistently and collecting useful loot along the way, there's no need to change locations just because another farming spot has stronger enemies.
Best Weapons and Damage Types for Book Bug Farming
The Book Bug farm works as a general weapon-leveling opportunity, but some weapon types may be more convenient than others.
Slash Weapons
Slash weapons with wide swings are useful for attacking groups of Book Bugs.
If several enemies are close together, a single attack may hit more than one target.
This makes Slash attacks a practical choice when you're trying to clear the encounter quickly.
Impact Weapons
Book Bugs have been reported to resist Impact damage.
That means clubs and other blunt weapons may take longer to defeat them.
You can still try leveling these weapons at the gargoyle puzzle, but compare your results with the skeletons elsewhere in the Tower of Knowledge.
Pierce Weapons
Pierce-focused weapons may also be less efficient against Book Bugs.
If you're leveling a spear, consider comparing the Tower of Knowledge farm with the fish-men near the Water Temple entrance.
The better location will depend on how quickly you can defeat the enemies with your chosen weapon.
Area-of-Effect Attacks
Attacks that strike multiple enemies are particularly useful for this farm.
Instead of chasing individual Book Bugs, allow them to gather and use a suitable wide-reaching attack.
This can reduce the time spent clearing each group.
What If You're Leveling a Weak Weapon?
If the weapon you're trying to level deals very little damage, don't rush into a large group.
Trigger a manageable encounter, keep enough space to retreat, and avoid fighting several gargoyles simultaneously.
A slightly slower but reliable run is preferable to repeatedly dying while attempting to level an underpowered weapon.
Alternative Weapon XP Farming Spots in Queen's Domain
The Tower of Knowledge Book Bug method is useful, but other locations may be more suitable for particular weapons.
Here are two alternatives worth considering.
Tower of Knowledge Skeleton Farm
There is another farming opportunity involving groups of skeletons near a save point inside the Tower of Knowledge.
This spot is worth trying if you're leveling an Impact or Pierce weapon that struggles against Book Bugs.
The advantage is that you can fight a more conventional enemy group without relying on the gargoyle puzzle.
Compare how quickly you defeat the skeletons with the time required for a complete Book Bug farming run.
Water Temple Fish-Men Farm
The Water Temple also contains enemies that can be useful for weapon leveling.
Look for fish-men near the four-key door at the temple entrance.
These enemies are worth trying when you're leveling a Pierce-oriented weapon.
Nearby centipedes provide additional combat opportunities and may drop elixirs.
If you're already exploring the Water Temple, this can be a convenient alternative before traveling to the Tower of Knowledge.
Which Weapon XP Farm Should You Use?
| Location | Why try it? |
|---|---|
| Tower of Knowledge Book Bugs | Large enemy groups and repeatable encounters |
| Tower of Knowledge Skeletons | Alternative for Impact and Pierce weapons |
| Water Temple Fish-Men | Pierce-oriented weapon leveling |
| Water Temple Centipedes | Additional enemies and potential elixir drops |
For general weapon farming, the Book Bug method is a strong choice once you've unlocked the Tower of Knowledge. However, it's worth switching locations if your current weapon takes too long to defeat the enemies.
Book Bugs Not Spawning? Common Problems and Fixes
If the farm isn't working as expected, check these possible causes.
1. You're Attacking the Correct Gargoyles
The farming method relies on activating incorrect gargoyles.
If you're following the correct puzzle solution, you may not trigger the enemy encounters needed for farming.
Try an incorrect statue instead.
2. You Haven't Rested at the Crystal Monument
After clearing the enemies, return to the nearby Crystal Monument and rest.
Simply walking away from the courtyard may not reset the encounter.
Use the monument before starting another run.
3. You're at the Wrong Gargoyle Location
Make sure you're at the outdoor walkway with iron railings and gargoyle statues mounted along the fence.
The surrounding bookshelves, stone pillars, and arched doorway are useful landmarks.
Not every gargoyle or book-filled room in the Tower of Knowledge is part of this farming method.
4. Your Weapon XP Is Increasing Slowly
If you're struggling to gain levels, consider whether your weapon is already at a higher level or deals an unfavorable damage type against Book Bugs.
Try a different enemy group and compare the time needed to earn another level.
5. Too Many Gargoyles Are Attacking
Gargoyle Warriors and Gargoyle Arbelists can make the farming area dangerous.
Don't trigger several encounters at once if you're using an underleveled weapon.
Deal with the immediate threats, use the nearby doorway to retreat when necessary, and return to the Crystal Monument to recover.
6. The Encounter Doesn't Reset
If you've rested but the gargoyle encounters still don't activate, check that you're targeting an incorrect statue.
The demonstrated farming loop works through repeated gargoyle encounters, but behavior may vary depending on your progression or game version.
If the statues remain inactive, try another farming location rather than assuming your save is damaged.
Frequently Asked Questions
Where is the best early weapon XP farm in Queen's Domain?
The Tower of Knowledge gargoyle puzzle is a useful early-to-mid-game farming spot. Incorrect gargoyle activations can summon groups of Book Bugs, which provide weapon XP and loot when defeated.
How do you spawn Book Bugs in the Tower of Knowledge?
Go to the numbered gargoyle puzzle along the outdoor iron fence and shoot an incorrect gargoyle. These activations trigger enemy encounters that can include large groups of Book Bugs.
Do Book Bugs respawn after resting?
The farming method uses the nearby Crystal Monument to reset encounters. After defeating the enemies, return to the monument, rest, and revisit the gargoyle puzzle to repeat the process.
