This mod for Dragon Age: Origins will give you a set of weapons based on the demonic spirits of the Fade. The set includes the following:

Longsword - Rage (Temper's Edge)

Battleaxe - Sloth (Slow Death)

Dagger - Hunger (The Devourer)

Shield - Pride (Pride Wall)

Staff - Desire (Breath of Desire)

If you have a previous version of the application, you can just delete it and download the new version. 

You can download the files using the DAUpdater.

If you get the error that says you need the 'custom items' set, just ignore it. This is normal and all you have to do is force load.
