Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
EvocationEffects and magic items with this trait are associated with the evocation school of magic, typically involving energy and elemental forces.
FireEffects with the fire trait deal fire damage or either conjure or manipulate fire. Those that manipulate fire have no effect in an area without fire. Creatures with this trait consist primarily of fire or have a magical connection to that element.
MagicalSomething with the magical trait is imbued with magical energies not tied to a specific tradition of magic. A magical item radiates a magic aura infused with its dominant school 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.
