craft homunculus question

[Cagemarrow]

Yep, Masterwork armor is practically free for my character. He has an at will item of Unseen Crafter and a ridiculous craft check with all the aid another they can give. It'd be like making GI Joe armor. Wouldn't help against saves though. He'd have to craft resistance items for that. Probably cheaper just to imbue an item with lesser globe of invulnerability for them, if that's available as a 3rd level spell.
