Fasten

Regular 
Ties up the subject with a length of rope or chain (which is not created by the spell, only animated). Useful to wrap packages, moor boats, bind prisoners, and so on. An actively resisting subject resists using DX. The bond is a normal knot (though it may be turned into a magical Knot by increasing the energy expenditure).

Duration: Permanent. 
Cost: 3 to cast (1 extra to have a Knot in it). 
Prerequisite: Knot.

Item 
A rope or chain which will wrap itself around the subject (which it must touch) when a command word is spoken; the enchantment is lost if it is cut or broken. 
Energy cost to create: 90 per yard of length.
