The Ruins of Illusk

In the southwestern corner on the docks, you'll see a strange statue next to a ruined house. Read the inscription, then enter the house. Inside, you'll be attacked by a skull warrior (6th-level undead/4th-level fighter). When it's dead, take its head and place it on the altar to open the seal to the first level.

A-To Ruined House B-Levers C-Fallen Hero D-To Level Two

Directly ahead of you, you'll see a large group of undead. If you don't feel like fighting them yourself, pull the two levers near the gate--one will send a jolt of electricity through the mob, and the other will summon a golem to finish them off.

Proceed through the ruins until you reach the fallen hero (10th-level paladin) and his 6th-level mummy buddy. Once the fallen hero has fallen, take his heart to the altar near the stairs in the southeast corner. Place his heart on the altar to break the seal.

The Ruins of Illusk: Level Two

A-To Level One B-Water Elemental C-To Level Three

Explore this level if you want. You'll find moderately difficult undead everywhere and some good treasure. To get to level three, kill the 15th-level water elemental in the northwest hallway. Search its body, take the blessed water, and place it on the altar to break the seal.

A-To Level Two B-Voleron C-Portal to Docks

The final level has quite a few enemies. Fight your way to the center chamber, where you'll face Voleron, a 15th-level wizard. Voleron is a lich and is immune to poison, paralysis, negative energy, critical hits, disease, death magic, sneak attacks, and mind-affecting spells. He also has a good variety of defensive spells. Once he's dead, loot the chamber and return to the surface via the nearby portal.
