Updated: 2026-10-16 · Published: 2026-10-16

Citadel of the Fallen Daeva is a five-player dungeon with Exploration, Conquest and Conquest [Hard] modes. The listed boss roster is Willful Turgen, Forbidden Hexbeast Griosa and Basilus the False. Use the current client to confirm the live entry and reward rules before committing a weekly attempt.
Mode Overview
| Mode | Minimum Item Level | Party size |
|---|---|---|
| Exploration | 3,800 | 5 |
| Conquest | 3,800 | 5 |
| Conquest [Hard] | 4,500 | 5 |
The snapshot records a Wednesday reset and weekly limits for Conquest modes. These values may be adjusted by a season or patch, so recheck the menu after maintenance.
Boss Roster
Willful Turgen, Forbidden Hexbeast Griosa and Basilus the False are the three named bosses. Because the available structured data does not contain complete cast or phase instructions, use Exploration to observe the encounter safely. Keep the boss facing consistent, spread only when a marker requires it, and assign a caller to identify repeating telegraphs.
Preparation Strategy
Citadel's large gap between the base modes and Hard makes it useful to separate access progression from encounter mastery. Reaching 4,500 Item Level should not be the only preparation. The group should also clear Conquest without repeated deaths, maintain resources between pulls and know who handles interrupts, cleansing and revival.
- Enter Exploration to learn the route and three-boss sequence.
- Confirm each member can sustain a full boss attempt.
- Move to Conquest for planned weekly rewards.
- Review deaths by cause rather than immediately adding more damage.
- Attempt Hard only with a stable normal-mode plan.
Build Checks
If the party cannot enter Hard, use the gear progression guide to find the smallest efficient Item Level gain. If it enters but fails, use the stats guide to distinguish accuracy, survival and output problems. A utility Stigma that prevents a wipe can be worth more than a narrow damage bonus.
Before Queueing
- Verify the mode and Item Level on every character.
- Check the Wednesday reset and remaining reward claims.
- Repair, empty inventory space and prepare recovery items.
- Assign party roles and a mechanic caller.
- Use Exploration for learning instead of treating it as disposable content.
Citadel rewards a group that separates entry requirements from real readiness. Learn the three encounters in the lower mode, then move up with a reasoned gear and role plan.
