The core aim of the Soulvizier mod is to provide a more challenging and diverse Titan Quest experience. Instead of focusing on a single aspect the mod expands on just about everything in the game: Discover a plethora of new items, fight hundreds of unique mini bosses, encounter rare bosses, forge new equipment and much more. Soulvizier is built upon Munderbunny's highly popular Underlord mod and it includes all his mastery reworks and additional content.
Definitely the best TQ mod I've ever played/seen :L
I love the changes to/the addition of:
-The Skills
-The Hero monsters
-The Mercenaries
-And the Souls
