Unbending Will is a cooperative clan dungeon in Architect where a squad defends a single objective against timed monster invasions. The Level 1 run is a defense mission: the whole team protects the Torch of Atrahasis while four waves of enemies push toward it, and the challenge ends the moment the final wave boss falls. It rewards clan currency, an attunement item, and shared Clan Treasury materials.
Quick answer: At Clan Level 5, spend 1,000 Clan Ancient Coins to activate Unbending Will Level 1 under Clan > Activities, then defend the Torch of Atrahasis through four invasion waves inside the 10-minute limit.
Requirements to unlock and start Unbending Will
Access sits under the Clan menu, and each difficulty tier is gated behind an overall Clan Level. Every activation draws 1,000 Clan Ancient Coins directly from the Clan Treasury, so the clan needs coins banked before anyone can open the dungeon.
| Expedition tier | Clan Level required | Activation cost |
|---|---|---|
| Level 1 | Clan Level 5 or higher | 1,000 Clan Ancient Coins |
| Level 2 | Clan Level 15 or higher | 1,000 Clan Ancient Coins |
| Level 3 | Clan Level 20 or higher | 1,000 Clan Ancient Coins |
Those coins come from the same clan loop that feeds the treasury. Running the Angbar Arena boss and clearing tesseract hunting grounds both return currency and materials to the group, which is what keeps enough Clan Ancient Coins on hand to fund an expedition.
Prepare the clan squad and activate the dungeon
The defense objective and time limit
At the arena’s center, the Torch of Atrahasis stands on a raised platform. Perimeter stairs and walkways, along with elevated grated bridges, surround it. Your sole task is to keep the torch standing until the run is over.
- The countdown starts at 10 minutes and shows “9 m 58 s left” as it begins.
- When enemies get to the torch, its integrity falls and this alert flashes: “Atrahasis’ Torch is under attack”.
- The run fails and the dungeon deactivates if the torch is destroyed, the team wipes, or time expires.
Split the squad into two roles. Send one group to the outer bridges and ramps to stop enemy packs before they descend, and keep a second group on the base near the torch to pick off fast runners such as boars and charging beasts and to pull aggro away from the objective.
Clear the four invasion waves
Each wave is announced by a system banner. Difficulty ramps from basic packs to elite monsters and a final boss, so hold your strongest cooldowns for the last push.
Wave 1 – First Invasion
Basic mob packs enter from the main bridges near the citadel gate, including Thorn Boars. Use wide area-of-effect skills to clear them quickly while the perimeter group locks down the entrances.
Wave 2 – Second Invasion
The banner warns, “Second Invasion will begin. Beware of monsters going after the torch.” Faster charging beasts and vanguard packs led by the Ironhorn Ape Alpha rush down the pathways, so the base group must intercept anything that slips past the bridges.
Wave 3 – Third Invasion
Mixed ranged and melee units swarm together, including Kiguru Master Archers, Kiguru Master Warriors, and more Thorn Boars. Concentrate area damage on the chokepoints and have ranged players pick off the archers standing on the outer walkways.
Wave 4 – Final Invasion
A red banner reads, “Final Invasion will begin. Stop the powerful monsters.” Elite enemies and heavy hitters spawn, including the Ancient Tree Giant, then the wave boss Kurkazu appears at the central dais. Collapse the whole squad onto the boss, taunt it away from the torch, and burn it down with high single-target damage to end the run.
Confirmation and rewards
Once Kurkazu and the remaining hostiles are down, the “Challenge Successful!” screen appears with your total time consumed and the line “You have passed Atrahasis’s Trial.” That screen is the confirmation the clear registered. A coordinated Level 1 run typically finishes in around five to six minutes, well inside the 10-minute cap.
| Reward | Quantity | Recipient |
|---|---|---|
| Clan Ancient Coin | 700 | Each participant |
| 2★~4★ Expedition Card Box | 1 | Each participant |
| Unattuned Records: Ragnar | 1 | Each participant |
| Expedition Enchanted Quill | 60 | Each participant |
| 4-Star Heart of the Star | 1 | Clan Treasury |
| 2-Star Heart of the Star | 2 | Clan Treasury |
The private rewards land in each participant’s inventory, while both Heart of the Star materials go to the Clan Treasury for the group. Unattuned Records: Ragnar is used to unlock and transcend the Ragnar Attunement Page, and Expedition Enchanted Quills level up Character-type Attunement Pages, so completing Unbending Will feeds directly into your attunement progress on top of restocking clan currency.
