Craftsman (3.5e Trait)
From D&D Wiki
You are exceptionally gifted in all forms of the crafts, whether it be Smithing, writing, enchanting or brewing. Those around you see you as a gifted crafts master, and look to you when they need a weapon fixed or some armour patched.
Benefit: Whenever using a Appraise, Craft, Decipher Script, Forgery and Profession skill you gain a +5 bonus to the required attribute.
Drawback: As a result of your increased crafting ability, any Profession skill that is not a craft and any Perform skill recieves a -3 deduction.
Roleplaying Ideas: A handy master smith, or a warrior who preffers to craft his own weapons. Perhaps even a thief fluent in multiple different languages able to fluently write in all of them and forge any signiature after only one sighting.
