Item: Bismuth Armor

Bulwark: The armor covers you so completely that it provides benefits against some damaging effects. On Reflex saves to avoid a damaging effect, such as a fireball, you add a +3 modifier instead of your Dexterity modifier

Invested: A character can invest 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).

Magical: 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.
