Opus of Elemental Substance
A collection of 1st- through 9th-level spells focused on six elemental forces: acid, cold, fire, lightning, thunder, and earth. The spells allow warlocks, wizards, sorcerers, and other spellcasters to wield these elements as weapons, defenses, and tools, freezing creatures, calling down destructive storms, turning foes to ash, and reshaping the world around them.
