Ofuda

Ofuda (御札 or お札 o-fuda, a charm) are inscribed strips of paper or other material used within the Shinto religion as amulets or talismans for purification, exorcism, or protection.

It is common for ofuda to have other abilities, such as timed explosion like explosive tags and sealing and barrier capabilities used in Fūinjutsu. It can also be used in large numbers to act as a distraction when escaping enemies.
