Overview
This is not a walkthrough of the main questline. This is a simple shortcut for people who don’t want to wait until they are the minimum level for the daedric quests (2 for Azura and Sheogorath) or don’t want to hunt around for the offerings.
Doing the thingy
As you have read above, this is a simple trick to get a daedric artifact level one (or if you are too lazy to find suitable offerings). It only works with Clavicus Vile’s quest, and here’s how it goes:
Step one Find and kill Umbra
This is actually harder than it sounds. Firstly, you must find her. To save you a long hike around Cyrodiil, she can be found it a Ayleid ruin named Vindasel. Vindasel is west of the Old Bridge and roughly due south of the Imperial City waterfront. Make your way past traps and the few rats and mudcrabs, and you will find her in a large chamber at the bottom of some stairs.
WARNING: She is VERY hard to kill along with having a full set of ebony armor, Umbra (the sword) is very powerful and she has an ability that heals her 2 health per second. Restore health potions and any other useful equipment is very highly recommended.
Step two Go to Clavicus Vile’s shrine with the Umbra sword
To find the shrine, go Northwest to “Ayleid Well” then go west until you see the shrine. You may have to wait or rest until you get the quest update saying that you have the Umbra sword. When you do, activate the shrine and give Vile the sword (yes, I know you have to give away the sword, but if you are doing this for the Blood of the Daedra quest for Martin, you have to). When you do, he will give you the Masque of Clavicus Vile, and you’ve saved yourself the 500 gold offering you have to give him other wise.
I hope this was helpful to you, and good luck on future quests!
