If you go to White Ridge Barrow (or something like that) you will find albino and flame spiders. In the sanctum you'll find a crazy lady who attacks you. On her you will find a key and throwable spiders. In another room you'll find a dead guy in a cage. Next to him is a machine that makes more throwable flame spiders. A book next to that has all the recipes. The spiders a very affective and are so cool. Some of them move in your hands!
Post some cool things you have found in Dragonborn.
