I do enjoy this dungeon crawl mod.

The boss at the end is a fantastic design. Powerful and challenging for PC's, while not constructed of absurdly impenetrable defenses (AKA the Beast of Talos). The dungeon has character, and it is woefully difficult to predict when fights will occur.

Some of the traps are quite predictable, but the I think there are sufficient traps to keep the PC's on their toes.

Ultimately, while the story is simple, and straightforward, the real feature of this mod is the well designed boss, and the surprise upon which the boss is sprung on the PC's.
