IWDification is a mod to bring some of the elements of Icewind Dale into the Baldur's Gate series of games. A lot of this project is based upon the work of the IWD-in-BG2 conversion project, which later formed the backbone of IWDEE. The mod adds various elements such as selectable bard songs, two-handed axes, and over 70 new spells into your BG2, Tutu, BGT, BGEE, or BG2EE game. Every component can be installed independently of one another.
Beta 4 is a major overhaul of the mod with a complete revamp of the new spells. Learn more on the forums, project page, or readme, or download the new beta.
