You should get a Dwemer sphere to follow you around, like I did. It will protect you with a sword and crossbow. You can find one in Kagrumez, if you can get past the trials. Only one of them is friendly, though, the rest WILL try to kill you.
On second thought, it might be safer to leave it. If you can actually get it without being horribly killed by magical automatons, you probably don't need the protection. Cool to have around though. Everyone is like "look out! a dwarven sphere is right behind you!" and I'm like "it's cool dude, he's with me" and they're all like "NO WAI" and I'm like "YA WAI"
