Transference short version

Transference of magical properties from one object to another is more complicated and dangerous than creating a new item from scratch, but it may be a cheaper procedure.

The craftsman must be able to create the same the final upgraded magical item he is actually making through the transference.

Determine the difference between the creation price of the object before and after upgrading. An NPC will take half this amount. A PC may use 1/4 of this amount. Half of the cost (that would have been used by PCs, not NPCs) is in magical ingredients. You can use Talismanic Components as substitute for this half of the cost.

Transference of a +1 bonus takes 2 consecutive hours or 4 hours that are not consecutive. A craftsman can work 8 hours a day on transference.

You can use Spellcraft or a related craft or profession skills for the check.
