Traits
This magic comes from the arcane tradition, which is built on logic and rationality. Anything with this trait is magical. A creature with this trait is primarily constituted of or has a strong connection to arcane magic.
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).
A tattoo is a type of item that is drawn or cut into a creature's skin and usually takes the form of images or symbols.
