Blade Phantom's Guide
Activate ◆ (manipulate)
A blade phantom's guide is a metal rectangle, often on a chain, etched with an image of a warrior in a fighting stance. When you apply a blade phantom's guide to a weapon, it summons a spiritual fragment of a warrior who was adept with that weapon. For 1 minute, you treat your proficiency with that weapon as equal to your highest weapon proficiency. This effect cannot affect a weapon whose level is higher than the blade phantom's guide (11th).
Traits
An item with this trait can be used only once. Unless stated otherwise, it's destroyed after activation. Consumable items include alchemical items and magical consumables such as scrolls and talismans. When a character creates consumable items, they can make them in batches of four.
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.
