This is the "witchsona week" (at least here in Spain is Sunday, so I'm still on time!). It's a week where artists draw themselves, or a character they like, as a witch and they post it on the internet.
If I were a witch, I think I would go to any bookshop or library looking for new or interesting books. I think using a little pot as a backpack (and with a quill-wand like) would be cute and fitting. One never knows when it could be useful XD. And yeah, I don't think I would be a fighter, more like a witch collector or something :)
