I have a 10 INT and 12 WIS, one of our allies has Medicine as a skill, nobody yet has Crafting. Is it possible to be good at Crafting (and later Magical Crafting) with an INT of 10 (never increasing)? Or would it be a better idea to invest in Medicine (Wis never going above 12).
As long as you pick up some skill increases and skill feats related to it, I don't see why you couldn't be great at crafting even with an INT 10. Maybe not the ideal situation admittedly, but if you're mostly crafting things a little below your max level it should be fine. The first couple levels (besides repairing I think) might be a little rough though.
Ohh, ya I would be using it for crafting magical gear. Not really using it for repairing shields, weapons, etc.
