SoD to BG2EE Item Upgrade is a mod for BG2:EE that imports many more items from Siege of Dragonspear into the game, placing them into thoughtful location in Shadows of Amn. 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.
Lastly, the mod also gives upgrade recipes to Cromwell and Cespenar to upgrade most of the imported SoD items.
Version 1.2.0 includes changes to some item names and abilities based on feedback from the community, along with more new items added from SoD. There are also new upgrade recipes, and even an update to an existing HLA that fills a major gap it had!
