This is an attempt to take the original BG2 mod by Caedwyr and port it to the Icewind Dale Enhanced Edition game system. Because the game has Sorceror kits, the GS kit can be chosen at the start of the game.
This mod won't run on the original version of IWD because there is no Sorceror class. Until some genius of IE can create such a class...
Current version of mod won't run on IWD2. Major work would be needed on a lot of files from this mod so they could be adapted to the file formats used by IWD2.
If IWD2 has no High Level Abilities, Quintessence Magic won't be needed or wanted.
If IWD2 has no provision for Sorceror kits then the only way to gain the class is via Add Kit, if that exists in the game. (Unless you totally hack the existing Sorceror class so that all Sorcerors are Geomantic Sorcerors.)
