The key boss in this area has two core skills: cone-shaped spitting and summoning minions. DPS must focus on dodging spits and clearing all minions quickly. Special attention should be given to green soft minions as they transform into slowing water after death, significantly affecting team movement.

This boss requires a tank at the entrance position. If unable to kick through shield walls, they can withstand up to 30 layers of damage. When targeted, it will release soul thorns that trap a player in place with continuous damage; DPS must quickly eliminate these thorns while keeping an eye on AoE damage timing.

Afters defeating this boss, all players should gather outdoors while preparing for the next phase. Ensure all enemies in the room are pulled out and eliminated before proceeding further.

The corridor enemies should also be cleared sequentially before returning to the initial position for final boss battle.

The final boss has two phases: In phase one, a noble will descend from above while his blood is drained by his wife using a healing ability called Vitality Transfer. Once this ability is fully charged, continue attacking until it's complete. This ability will trap one player in a green circle outside of combat; healers need to dispel it while avoiding AoE effects from spreading.

In phase two, after using Vitality Transfer three times, his wife will leave combat while providing corruption vitality buffs to his noble each time it's used. This means P2 stage noble carries three layers of corruption buffs increasing 9% damage and speed. Focus on eliminating noble first as his wife only has an inability skill that doesn't pose significant threats.

The Tail Boss (final boss) requires special attention: its summoned minions have an unbreakable stun skill that causes continuous damage once activated. Use hard controls like stuns or silences to interrupt these skills immediately after activation and quickly eliminate minions before they can re-activate.

Afters defeating Tail Boss, be sure to collect any glowing potions dropped on enemy corpses and use them on corpses before bosses reach full energy (to prevent resurrection). Also pay attention to interrupting any dark lightning castings from bosses during combat.

This instance is relatively easy if you focus on controlling minions and managing corpse disposal effectively during each phase of battle.
