Name

Enchantment 
Gives a magical name to an enchanted object. The magic of the subject functions only for someone who knows its name. The user must speak the item’s name the first time he tries to use it, to show he knows the name.

Energy cost to cast: 400, or 200 if the name is written on the item. It must be readable (GM’s decision). It may be small, hidden, or even disguised, but a person examining the item must be able to see it. This provision is a major reason for the popularity of dead and obscure languages among wizards – writing your item’s name on it in an extinct language is almost as safe as not writing it at all, and much cheaper. 
Prerequisite: Enchant.
