SoD to BG2EE Item Upgrade is a mod for BG2:EE that brings in many more items from Siege of Dragonspear, IWD, and even new spells to BGEE, BG2EE and EET, placing them into thoughtful locations througout the campaings of each game. The mod also has an optional component to force importation of the SoD items that a player can normally import into BG2:EE at their normal locations, along with other optional components for cromwell's equipped items, choice of items imported from BG1 to BG2, and item rename/recolors for consistency.
Many of the newly added items also have upgrade paths via Cromwell and Cespenar!
Not to leave out the more magically-inclined, the mod even includes several new spells!
Version 2.0.0 brings *tons* more items in from SoD and IWD, adds support for BGEE, more spells, revised upgrade for several items, and the code has been completely reworked for better compatibility with EET so that you can enjoy this mod throughout your Bhaalspawn's entire legacy!
