The Dragonborn challenge-You can choose any race and level up your skills however you want, however the only weapons you are allowed to use are the ones that appear in the offical artwork of the Dragonborn:
Steel Sword Steel Dagger Banded Iron Shield Orcish Bow (not in offical artwork, but thought about archers) Any type of Arrow
The armor you can use is:
Iron Helmet Studded Armor Iron Gauntlets Iron Boots
You are allowed to use any other armor or weapons until you get this set, but once you do, you are not allowed to use any other equipment. You are allowed to improve your equipment through a grindstone/workbench, and you may enchant it if you know any enchantments. You can also use magic rings, necklaces, or spells. You can have other weapons and armor in your inventory, but you aren't allowed to use them.
If you guys want to add to this rule list, just say so and I'll adjust it accordingly.
