Huh, I hadn't even thought of being a sculptor or tailor or something. What sorts of skills would an earth golem probably require?
Sculpting or Earth Magic to make the body, probably. Runecrafting to empower it, and either Summoning or Necromancy to activate it. Other ways are possible, for example Cheddarius' Flesh Golem was made with life magic, and you could possibly use Metamagic to enchant it instead of Runecrafting(I originally intended Runecrafting to be the only way to make magic items, but then Acanthus got some good rolls when imbuing those weapons with force.) The whole point of having multiple schools is to combine them to get different effects; I love it when my players develop new and unexpected ways to accomplish things that I never thought of, but still make sense logically. Of course, I still have to base the results on what the rolls give me; there have been several experimental spells that have been tried that I desperately wanted to see succeed, but got bad rolls and thus failed; there have also been attempts to do something really weird that I didn't like, but they got a 5 so I grudgingly let them do it.
As far as mundane skills like say, smithing or carving; they might not really be useful in combat, which may be why they have been neglected, but they do have their uses. For example, smithing can be used to make raw items to enchant, forge or repair weapons and armor, or even make golems if you find enough metal. Carving has similar uses, though bone weapons might be rather weak; despite that, bones and shells are more readily available than metal, for example. Magic can also help with crafting; certain types of magic could be used to strengthen and enhance bone and leather for example, or fire used to smelt large quantities or ore to use with smithing. In generally, if someone comes up with some interesting idea that makes me stop and think "Hey, that's cool!" they will get something really nice out of it. Unless they roll a 1, in which case they will blow themselves up.
