Each specialist's ring is dedicated to a single school of magic, and the ring is covered in symbols and glyphs related to that school according to the creator's arcane studies. A specialist's ring has the trait corresponding to its school of magic. You gain a +2 item bonus to Arcana checks, and a +1 circumstance bonus to recognize magical effects and items of the specific school of magic.

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.
FocusedAn item with this trait can give you an additional Focus Point. This focus point is separate from your focus pool and doesn't count toward the cap on your focus pool. You can gain this benefit only if you have a focus pool, and there might be restrictions on how the point can be used. You can't gain more than 1 Focus Point per day from focused items.
InvestedA character can wear only 10 magical items that have the invested trait. None of the magical effects of the item apply if the character hasn't invested it, nor can it be activated, though the character still gains any normal benefits from wearing the physical item (like a hat keeping rain off their head).
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.
