This spell was pioneered by the Kuni family but has come into use among other shugenja who battle the forces of the Shadowlands, such as the Scorpion and the Phoenix. It is used to safely imprison minor Shadowlands creatures, typically for purposes of interrogation. Any Shadowlands creature with an Earth of 3 or less can be targeted with this spell. It cannot affect the Lost, Oni Lords or their spawn, or creatures with an Earth of 4 or higher, nor can it affect creatures who are not Tainted.
If the spell is cast successfully, it calls forth manacles of iron, formed from pure Earth spirits, which trap and bind the target creature, rendering it physically helpless for the duration of the spell. When the spell expires, the manacles instantly crumble away into dust.
