Vicious Purist Playthrough #1: Namtar's Lair beaten by an Orc Rogue. Submitted for the approval of the Midnight Society, I call this "The Tale of the Evil Sorcerer Who Went Down Like a Chump."
I promise not to use the Rogue too often in future entries. Other classes can beat vicious, too! I'm actually planning on Dragon Isles with an Assassin next, but I'm happy to take suggestions (and comments and/or criticism, of course).
EDIT: Here's the playlist with every video in this series. Now almost as long as the Lord of the Rings trilogy!
