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.
MythicOptions with this trait grant or utilize mythic power. Feats with the mythic trait can only be taken by mythic characters, who are typically characters with a mythic Calling.
Monsters with the mythic trait have access to a pool of Mythic Points and are particularly strong for creatures of their level. Many mythic monsters are either resistant or entirely immune to attacks from non-mythic creatures and weapons.
Spells with the mythic trait require the expenditure of a Mythic Point in order to be cast, and items with the mythic trait require the expenditure of a Mythic Point in order to use their activated abilities.
Weapons with the mythic trait overcome the resistances and immunities of mythic monsters.
