Runecasting is a personal favorite of mine.
You can take:
-2 Ritualist (Runes)
This gives you the ability to cast thaumaturgy spells that directly relate to Rune Magic, like Wards. It also gives you two focus item slots, which can be converted into enchanted items and potions. Runes can pretty much describe any enchanted item. You could have a Rune on your Axe that covers it in flame, a rune on your boots that shield you from harm, one use runes that shield you from sight, etc. Sigrun Gard in the books is a Runecaster, and she is awesome.
Remember to take refinement for more item slots. Lore is the primary skill for Runecasting. Wouldn't be bad to spend the extra piont of refresh and pick up thaumaturgy at some point, putting the specialization into either runes or crafting.
