This is the second Expansion for the 2002 RPG *Neverwinter Nights*, requiring the base game. It adds a dark, 20-hour single-player campaign set in Waterdeep and the Underdark, designed for high-level heroes. Its core feature is introducing Epic Level gameplay, allowing characters to advance from level 20 up to level 40. New content includes prestige classes like the Shifter, dozens of new feats, spells, weapons, and challenging creatures such as Mind Flayers and Beholders.
The expansion delivers a new, approximately 20-hour single-player campaign. This narrative journey takes characters from the famous city of Waterdeep down into the treacherous and foreboding depths of the Underdark. The atmosphere is described as dark and dangerous, challenging heroes who must face a final, overwhelming terror to protect the Forgotten Realms. It is crafted for characters already operating at a high power level, testing their accumulated skills and faith against insurmountable odds.
The most significant mechanical addition is the implementation of Epic Levels, based on the ruleset from the *D&D Epic Level Handbook*. Characters who reach the standard maximum of level 20 can now continue to advance, pushing their capabilities as high as level 40. This system fundamentally alters character power scaling, allowing for vastly more powerful heroes.
To support this elevated level cap and challenge, the expansion introduces a wealth of new content:
As an expansion, this content is not standalone; it builds directly upon the existing *Neverwinter Nights* foundation. It is designed to seamlessly integrate new mechanics, creatures, and the extended level progression into the established game world. Furthermore, the expansion features 17 new musical tracks composed by Jeremy Soule to enhance the atmosphere of the new environments.
No additional official expansions or downloadable content (DLCs) were released for this title. This expansion represents the final major content addition to the original *Neverwinter Nights* release.
