Some "New" Spells
This free six-page web enhancement presents ten spells from the d20 System Reference Document converted for use with the Arcana Unearthed and Arcana Evolved magic systems. It includes standard, heightened, and diminished versions, with some spells given new or altered names to distinguish their effects and support setting-specific storytelling. Several spells form thematic sets, while others provide practical utility options. A few include racial descriptors introduced in Arcana Evolved; these do not affect use with Arcana Unearthed. The heightened and diminished versions can also be adapted for other d20 games.
