The Item Upgrade for Icewind Dale mod is a modest collection of upgrades for various items throughout the game. Reading through the item descriptions, the developers really took a lot of time to give many items an elaborate backstory. In many cases, I felt that an upgrade was a chance to tell a bit more of the story. Version 6 addresses some bugs from previous releases.
Download version 6, join us on Discord or the forums, or learn more about the mod from the readme or project page.
