Focus Item

A Monster Vulnerability.
From the Book of Engoku:

Description

Some beings are bound to a particular object to maintain their powers. While the object varies by case, the results are always the same. Creatures who are separated from their Focus for more than a 100 count, for whatever reason, lose all abilities and are forced to fight as a Peasant (in other words, no armor and only one melee weapon) for the remainder of that life, or until the object is recovered, whichever comes first. Foci are always returned to the player before every life. Some Focus Items have additional benefits and/or restrictions, see entries for more information.
