Description: You know the secret of repairing magic items, even ones which have been completely destroyed and can reforge an item so that it does not lose its magical abilities.

Prerequisites: INT 15, Craft Magic Arms and Armour, Craft Rod, Craft Staff, Craft Wand, Craft Wondrous Item or Forge Ring

You can reforge magical items fully, so that even if they are completely destroyed and then reformed, they retain their magical essence. The cost of repairing the item is equal to one quarter the experience, the raw materials and time necessary to craft the item in the first place. If you are successful in your Craft check, the item is reforged and regains its full powers. You can only reforge magical items which you are capable of creating, so you may only reforge items for which you have the correct item creation feat.

In addition, the Reforge Item feat can be used to restore magical power to an item which has been successfully disenchanted through the use of disjunction or other, similar spells and spell-like effects. In order to do so, you must expend half the amount of experience, materials and time necessary to craft the item in the first place. Rather than simply using the Craft skill to repair the item, you must instead succeed at both Craft checks and Spellcraft checks against a DC equal to double that required to craft the item in the first place. So, for example, to reawaken the enchantment in a longsword, you must succeed at both DC 30 Craft and Spellcraft checks for the duration of the repairs.
