The Band of Mimicry

The Band of Mimicry is able to take the power of any magic item it has touched. It doesn’t have a limit of how many powers it can hold, but if it breaks it loses all of its powers, except for the one to copy powers of other items. If this band breaks and gets turned into another item (IE: A sword), the sword would get the power that the band would.

If someone’s soul somehow gets trapped within the item, they get a weakened version of this power.
