Description: You can leech the life force and experience of others to power the creation of magic items, allowing you to preserve your own energies.

Prerequisites: INT or WIS 17, Any Item Creation Feat

You can take arcane fuel, in the form of experience points, from willing beings to empower those magic items you create. In order for you to leech another being’s experience, they must be present throughout the crafting process. You make take any number of experience points from the being, up to half the cost required to enchant the magical item. You cannot take experience from the being to pay for any abilities which cast or replicate spells with an experience point cost, other than Item Creation abilities. As always, if the enchantment process is abandoned, or if it is for any other reason ruined, the leeched experience points are lost. Only one being, not including the crafter, can donate experience to the creation of each magic item.

Special

If you have the feat Improved Item Creation, its benefits extend to those from whom you leech experience, meaning they need only sacrifice experience in an amount equal to 1/50th of the base price of the item to be enchanted.
