Magical substances were special materials that occurred in the natural world. Sometimes inert on their own and sometimes dangerous to encounter, they were often employed to create or enhance magical items and Spells. These substances could include rare metals, enchanted herbs, living spores, or unique crystals that had inherent magical properties. They were often required as components for spellcasting or crafting and were usually difficult to find or expensive to acquire.
In practice, magical substances were essential for producing powerful items or performing complex spells. Their quality and rarity could affect the strength and effectiveness of the magic involved. Adventurers often needed to seek out these materials during their journeys to repair or upgrade their equipment or to complete important magical rituals. Without these substances, many magical effects would have been impossible to achieve.
