Sendai's Enclave

Sendai's Enclave - Exterior: Arrive near a cottage. Search containers for loot and the Rune of Clangeddin. Speak to the Woodcutter, who directs you west. Prepare for confusion attacks. You will be ambushed by two Drow, two Umber Hulk Elders, and a Hive Mother. Focus on the Hive Mother. Return to the Woodcutter, who directs you to graves in the northeast. You will be ambushed by two Gauths and five Drow. Return to the Woodcutter, set traps, and buff up. The Woodcutter and nearby animals reveal themselves as Drow. Defeat them, including a Drow Wizard and Thieves. An illusion hiding the entrance to Sendai's Enclave will be dispelled. Kill the two Warriors and a Thief guarding the entrance, and clear a trap. Protect against confusion and enter.

Sendai's Enclave - Entrance: Encounter Myconids, a Myconid King, and four Spore Colonies. Prioritize destroying the colonies. Umber Hulks, Mutated Spiders, and a Sword Spider will join the fight. Continue forward, defeating more Umber Hulks and spiders. On a platform with Drow and Umber Hulk Elders, draw enemies away. Continue northeast into the Drow Barracks. Defeat Drow Warriors, a Drow Priestess, and their Captain, Thelyn'ss. Loot the Amulet of Cheetah Speed and the Drow Guard's Key from Thelyn'ss. A cutscene with Sendai plays, granting 5000XP per party member. Choose between the North Tunnels or South Tunnels.

Sendai's Enclave - North Tunnels: Face Derro crossbowmen and Berserkers, driven by the Slavemaster. Press forward as Derro continuously spawn. Avoid ranged attackers getting surrounded. The Slavemaster will appear multiple times before engaging directly. Kill the Slavemaster to stop spawns.

Sendai's Enclave - South Tunnels: Cast Mass Invisibility. Find the boss spider, Lashar'ra. Have poison-immune party members attack her and then deal with the swarming spiders. Clear trapped webs on the sides for experience.

Sendai's Enclave - The Lich's Lair: Buff up and cast Chaotic Commands. Defeat Drow and two Umber Hulk Elders outside the lair. Enter the lair. Use a Scroll of Protection From Undead on your Thief and enable trap detection. Disarm traps leading to Odamaron's platform and defeat him. Loot the Drow Wardstone, the Eye of Tyr, and the Heart of the Damned from Odamaron. The trapped container near the entrance holds potions and the Skull of the Lich. Other containers have minor loot and magical ammo. A cutscene with Sendai plays, granting 5000XP per party member. Defeat Drow and two Umber Hulk Elders on the central platform. Use the Drow Wardstone to enter the Inner Sanctum.
