Wizardry: Sandstorm Spells
Sandstorm is the desert counterpart of Frostburn. While it does have some rather infamous bits, overall it's a decent book. However, the spells section is rather underwhelming, with many spells being spells taken from Frostburn and reversed to be hot instead of cold. Despite that, there are some unique ones that definitely cannot be found anywhere else. So, here's all the spells from that book that I deem worth adapting to my games.
