Chain of the Magus, Lesser
Chain that locks whatever it touches
When placed on a portal (door, window, etc.), this eight-foot segment of iron chain clings to its surface and makes it impassable until removed by the one who placed it there, or until a command word is spoken and it is taken down.
Likewise, if the chain is used to bind a creature, the creature automatically fails any Escape Artist check to free himself. Again, the Chain remains in place until the aforementioned conditions are met.
If the Chain is placed on an open door, the door is “locked” open.
In any of these situations, the Chain can be moved in the same manner as an Immovable Rod.
This Chain was one of the many possessed by the Magus of Chains
