The complete Tentacle Quest begins with the four route keys in Tarnstead, continues through the underground passages and four personal throne powers, and ends in the Tentacle castle with the Black Skeleton Outfit scroll, Tentacle Earrings and a Ritual Reaper Doll.

Full spoiler: this walkthrough includes the key locations, switches, thrones, castle trials and reward chests. Click any illustration to enlarge it. Coordinates use x, y, z; surface is normally z=7, smaller z means upstairs and larger z means underground.

Season 3 route status — 15 October 2026: a confirmed map error currently disables the lava gate and the original passage lever. If you reach these points and cannot continue, wait for the map correction to be loaded. The instructions below identify the original quest locations; copied objects are not alternative quest objectives.

Route: Travel and preparation → Four Tarnstead keys → Underground entrance → Four throne powers → Blood gate and lava passage → Castle switches and solo room → Changing tiles → Destruction and rewards → Exit and shortcuts.

Preparation and travel

• Finish Viper Island Quest, including Sareth's final hi → mission → yes report. This unlocks travel to Tarnstead.
• Bring the Dragon Key 25780 obtained on the earlier Devil Hills route, or a Key Ring containing that key. It opens the first Tarnstead door. The Viper finale does not replace this key.
• Bring a rope and shovel, enough supplies for a long route and equipment suitable for Dark Slayers, Dark Hunters and the Tentacle family. A team helps in the open underground sections; one castle room admits only one player at a time.
• Keep the four keys found during this quest. You can use a key directly on its matching door, or use your Key Ring on the door after adding the key to it.

From Captain Venomwake on Viper Island, say hi → tarnstead → yes. The voyage costs 175 gold and lands at 31550,32777,7. Admiral Rolfe also serves Tarnstead for 6,000 gold once the same access is unlocked.

Choose tarnstead for the first run. The deep tarnstead route is a later shortcut unlocked by claiming the final outfit reward.

The Death Order NPC missions are a separate branch. The Tentacle route below advances through keys, switches, thrones and chests.

Tarnstead: the four route keys

1. Enter the western route and collect the first key

1. From the Tarnstead landing, reach the locked door at 31465,32787,7. Open it with Dragon Key 25780.
2. Reach the hill near 31459,32819,7 and climb to z=6.
3. Use the dead tree at 31460,32815,6. It gives Dragon Key 25781.

2. Cross the tower route for the second key

1. Climb the central tower using the ladders at 31472,32824,7 (to z=6) and 31472,32823,6 (to z=5).
2. Climb the central tower using the ladders at 31472,32824,7 (to z=6) and 31472,32823,6 (to z=5).
3. Use Key 25781 on the door at 31458,32822,5.
4. Descend at 31458,32825,5, follow the connecting passages, then go down at 31481,32843,6 to the eastern lower chamber on z=7.
5. Use the dead tree at 31481,32849,7. It gives Dragon Key 25782.

3. Climb for the third key

1. Climb back up the ladder at 31481,32843,7, then return to the tower door at 31456,32830,5 and open it with Key 25782.
2. Climb to z=3.
3. Use the bookcase at 31445,32836,3. It gives Dragon Key 25783.

4. Collect the last key and enter the dungeon route

1. Open the upper door at 31451,32827,3 with Key 25783.
2. Use the chest at 31448,32826,3. It gives Dragon Key 25784.
3. Descend to the door at 31472,32814,7, open it with Key 25784, and follow the underground descent.

All four pickups record a separate personal claim. An it's empty message means that character already collected the key. Check the Key Ring if the loose key is no longer in your backpack.

The underground entrance

The first underground hub is on z=13, near 31477,32867,13. Progress north through the entrance chamber.

1. Use the western entrance lever at 31466,32846,13. It opens the passage at 31477,32850,13.
2. Use the eastern entrance lever at 31488,32846,13. It opens the next passage at 31477,32848,13.
3. Prepare for the Tentacle Slayers and Archers summoned when these switches are activated. Clear the chamber before continuing.
4. Explore the underground branches and collect the four throne powers below. Return to this hub afterwards for the blood gate on z=14.

Switch rules: these are shared passages. A teammate can open them for the group. Each entrance switch has a 10-minute reuse delay; passages reset after 2 hours 40 minutes. Using an already activated switch again can close its passage. Do not toggle an open switch just to record personal progress.

Underground entrance: both battle levers

Open this floor in the world map

The four personal throne powers

Every player must walk onto each of the four required throne powers personally. Opening a passage or following a teammate onto a throne does not give the teammate's progress to you. They can be collected in any order. The success text confirms that you touched a Succubus throne and absorbed its spirit.

Power	Throne location	What to do
Western upper throne	31426,32959,12	Reach the western branch and step onto the throne.
Deep southern throne	31511,33016,14	Step onto this original throne. The copied throne at 31417,33028,14 is inactive on Season 3; it does not grant a power.
Eastern upper throne	31525,32907,12	Reach the eastern branch and step onto the throne.
Death Guardian throne	31553,32950,14	Clear the Death Guardian route. Its death opens a temporary portal at 31553,32960,14 to 31553,32952,14. Cross within 4 minutes and step onto the throne.

Keep track of the four distinct powers at the original locations in the table. Returning to a throne that already accepted you does not grant a fifth power. The blood gates require these four. Extra copied objects shown in the regional map are not additional working quest points.

The blood gate and lava passage

1. Return to the northern entrance hub and go to z=14.
2. Stand at 31477,32842,14 and use the gate immediately north at 31477,32841,14. With all four personal throne powers, it moves you to 31477,32840,14.
3. Enter the portal at 31476,32838,14. It leads to the lava passage at 31481,33008,14.
4. At the second throne gate, stand at 31485,33007,14 and use the door at 31484,33007,14. It checks the same four powers and moves you west to 31483,33007,14.
5. Use the original lava-route lever at 31572,33007,14. It opens the wall at 31521,32973,12; leave the passage open and continue through the connecting floors. The extra lever at 31478,33019,14 is a copied map object, not an intended alternative.
6. Reach the castle portal at 31450,33002,12. It leads to 31321,32920,8, the first floor of the final castle route.

If a gate says You did not absorb enough blood energy from thrones!, revisit the four distinct powers with that character. Lever activation does not substitute for a personal throne visit.

Tentacle castle: switches and the solo room

5. Open the three castle passages

You arrive on z=8. Use the switches below as you work through the castle maze. Each opens the indicated obstacle for everyone; they reset after 2 hours 40 minutes and can be closed by another toggle.

Switch	Location	Opens
Switch A	31335,32928,8	Passage at 31338,32927,8.
Switch B	31340,32920,8	Passage at 31334,32924,8.
Switch C	31333,32926,8	Passage at 31341,32933,8.

6. Pass the solo combat chamber

1. Reach the portal at 31360,32923,8. Only one player can occupy the combat room at a time. If it refuses entry, wait for the previous player to leave.
2. Enter and defeat the Tentacle Slayer, Tentacle Archer and Tentacle Archmage. Your entry begins a fresh encounter.
3. Leave through the northern room portal at 31355,32919,8, which returns you to 31355,32917,8.
4. Continue to the portal at 31357,32913,8. It takes you to 31361,32919,9.

Open this floor in the world map

The changing tiles

On z=9, reach the platform spanning 31321–31340,32919–32926,9. Its unoccupied tiles change every second. Stepping onto a currently marked tile summons a Tentacle Phantom and has a 1% chance of sending that player back to the underground entrance at 31477,32867,13.

1. Cross the platform toward its south side, clearing the enemies it produces.
2. Stand on 31322,32926,9, 31323,32926,9 or 31324,32926,9.
3. Use the southern door at 31323,32927,9. It moves you beyond the platform to 31323,32928,9.
4. Use the portal at 31336,32928,9 to continue to 31324,32919,10.

The random return is a setback. To advance, cross the platform and use its south door. Your throne powers remain recorded if a tile sends you back.

Final castle floor 9: shifting floor and one-way exit

1 — Shifting floor: Phantom spawn point (31323,32925,9) · 2 — Use door from the north side (31323,32927,9) · 3 — Portal to floor 10 (31336,32928,9)
Open this floor in the world map

Destruction and the reward floor

7. Cross Destruction's passage

1. On z=10, fight through to Destruction and defeat it.
2. Its death opens a portal at 31358,32923,10 to 31353,32925,10. The portal lasts 4 minutes; have the group ready to cross.
3. Continue to the portal at 31354,32912,10. It leads to 31358,32937,11.

Final castle floor 10: Destruction and reward route

1 — Destruction: temporary portal (31358,32923,10) · 2 — After the temporary portal (31353,32925,10) · 3 — Portal to floor 11 (31354,32912,10)
Open this floor in the world map

8. Claim both personal rewards

On z=11, collect both of these rewards:

Location	Reward	Why it matters
31358,32906,11	Black Skeleton Outfit scroll	Records quest completion and unlocks the post-quest shortcuts and deep Tarnstead travel. Use the scroll to learn the outfit.
31351,32910,11	Bag containing Tentacle Earrings + Ritual Reaper Doll	Separate chest reward. Claiming this chest also unlocks the normal quest exit.

These rewards belong to each character. Collecting the outfit reward does not automatically collect the earrings chest.

Final castle floor 11: quest reward and extra chest

1 — Black Skeleton outfit and quest completion (31358,32906,11) · 2 — Additional reward chest (31351,32910,11) · 3 — Portal back to the caves (31362,32914,11)
Open this floor in the world map

Exit, shortcuts and optional routes

Leave after collecting the rewards

1. Use the return portal at 31362,32914,11. It leads to 31485,32883,13.
2. Return north to the entrance hub.
3. Use the exit portal at 31483,32839,13. After claiming the earrings-and-doll chest, it returns you to Tarnstead at 31492,32777,6.

Return for later visits

After claiming the Black Skeleton reward, the two entrance-hub shortcuts are available:

• 31472,32840,13 → final castle entrance at 31323,32919,8.
• 31479,32838,13 → deeper southern area at 31502,33048,14.

The deep tarnstead boat route also becomes available, provided Viper Island's final report is complete.

Optional lava / crafter access

Walk onto the lava-route tile at 31489,32884,14 to record that access. Afterwards the crafter portal at 31504,32875,12 takes you to 31486,32883,14. This is an additional unlock; it does not replace the four throne powers or either reward chest.

Sacrifice tile and Tentacle crafting room

1 — Sacrifice tile (31489,32884,14) · 2 — Sacrifice portal destination (31486,32883,14) · 3 — Tentacle Blacksmith (31502,32883,14)
Open this floor in the world map

Optional Apocalypse encounter

The boss switch at 31358,32904,12 summons Apocalypse at 31353,32924,12. It has a shared 5-hour reset. This is an additional boss encounter; the reward chests above do not require a personal Apocalypse kill.

The Tentacle General's Monster Point challenge is a separate activity from this walkthrough.

If progress stops

• Boat refuses Tarnstead: finish the Viper finale and Sareth's final report. Choose tarnstead for your first visit.
• First door stays locked: use Dragon Key 25780 or the Key Ring that contains it. The four keys collected on Tarnstead are for later doors.
• A tree, bookcase or chest is empty: that character already claimed its key. Check the Key Ring and stored equipment.
• An entrance lever refuses reuse: wait for its 10-minute delay. An already open passage does not need another activation.
• Blood gate refuses entry: that character needs all four distinct throne powers at their original locations. The copied southern throne is inactive. Season 3 also has the confirmed map issue described above; completing the thrones alone cannot bypass that issue.
• Solo-room portal refuses entry: another player is still inside. Complete the room one character at a time.
• Changing tiles send you away: return through the route; the personal throne powers are retained.
• Death Guardian or Destruction portal disappeared: the temporary passage lasts 4 minutes after the boss dies. Return when the encounter is available and open it again.
• Exit says the quest is unfinished: collect the separate Tentacle Earrings / Ritual Reaper Doll chest at 31351,32910,11.
