To the best of our current knowledge, none of the str/dex/etc. attributes effect crafting.
Could someone please tell me which attribute effects crafting? im not sure that there is one but id rather know than not no, just in case im ******** up.
Craftsmanship, Magical Craftsmanship, and Control are the three 'stats' that effect crafting that we know about at the moment.
It's true the Craftmanship and Control are the primary DoH attributes, but not sure where you're ruling out physical attributes in affecting crafts. There is plenty of empirical evidence on this very forum of certain attributes helping certain craft classes (INT for ALC, DEX for BSM, MND for GLD, etc).
Even without the actual data, what would be the point of physical level if the bonus it provides wouldn't help DoL/DoH? Think about it...
Djigga, please. Highland Hyurs can't jump.
