Traits
Spellbooks are useful tools for any magic user to write down incantations and runes of power, but where most spellbooks are nothing more than ink on parchment, grimoires have absorbed the magic of the spells within—magic that knowledgeable spellcasters can use to augment their spells.
Something with the magical trait is imbued with magical energies not tied to a specific tradition of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
