A massive vault door, etched with alien runes, shimmering with eldritch energy.
巨型庫門刻滿異域符文，縈繞著詭譎奧術靈光。
PLAYER REFERENCE
Loot, durability, and target priority
The highest-value late target of the five Dens: it has the highest health roll, but also the most loot, the best base artifact chance, and guaranteed Mithril.

When to prioritize it
Prioritize it when artifacts or Mithril are the current bottleneck and you can reliably destroy it before the mountain is consumed.
How to clear it efficiently
- Use Death Mark or focused Ballista fire so its high health does not split your main damage for too long.
- Make room in the hauling line before the kill; 5–8 loot items plus Mithril or an artifact can create an immediate logistics spike.
- If the clear badly stalls the current mountain goal, improve Den damage before treating the Vault as a reliable reward engine.
