Friend’s of ours decided to film and do a guide on their kill of Duke Letareus in Greenscale’s Blight.
Anyway, not much to say so just watch the video
If you like the video, then I would suggest subscribing to their page. They are starting to get the hang of doing guides and will probably release more and more in the future.
If you want to compare to their last video, then I suggest you take a look at this post about Konstantin.
