Cooperative Crafting
Your assistance makes item crafting far more efficient.Prerequisites: 1 rank in any Craft skill, any item creation feat.
Benefit: You can assist another character in crafting mundane and magical items. You must both possess the relevant Craft skill or item creation feat, but either one of you can fulfill any other prerequisites for crafting the item. You provide a +2 circumstance bonus on any Craft or Spellcraft checks related to making an item, and your assistance doubles the gp value of items that can be crafted each day.
This feat was created prior to technological items being a thing, so we are reading this two different ways. My character, a wizard, wants to be able to help the other player's character, a techie, craft tech stuff. The wizard has all of the relevant craft skills, but no Craft <technological item> feats. This game is a futuristic one so the GM has ruled that the Technologist is not needed. Even if that wasn't the case, we can assume that the wizard had it and continue on with my question.
What is the general rule on this? Even if the tech craft feats are ruled to be "item creation" feats (for this purpose only, perhaps), since you must possess the relevant Craft skill OR item creation feat, can the wizard help the techie build a technological weapon even though he doesn't have the Craft Technological Arms and Armor feat?
As I read it, the "or" means that you must both possess the relevant Craft skill if you are making a mundane item or the relevant item creation feat if you are making an item that requires one. So the wizard is useless to the techie.
I could see a technical reading going the other way since the tech craft feats are not marked as 'item creation' feats, but IMHO it's better to keep it parallel to magic items. YMMV.
You both need to have the base requirements to craft said item type for the feat to work.
