Spells Per Day: When a new Dweomercrafter level is gained, the character gains new spells per day as if he had also gained a level in a spellcasting class. He does not, however, gain any other benefit a character of that class would have gained (improved chance of controlling or rebuking undead, metamagic or item creation feats, hit points beyond those he receives from the prestige class, and so on), except for an increased effective level of spellcasting. If a character had more than one spellcasting class before becoming a Dweomercrafter, he must decide to which class he adds the new level for purposes of determining spells per day.
Power Reduction: When creating any item (wands, rings, constructs, etc.), the experience point cost is cut by 5%. This ability is always applied last.
Power Sharing: When creating any item using an item creation feat, the experience point cost may be shared by any other willing and uncompelled spellcaster with the same item creation feat.
