Yeah, not too tough. You should be able to plow through these fairly easily. Then again, you don't already have 100% on the vicious dungeons, so I suppose it could take awhile.
We made an expansion and it is awesome. Really, you should check it out, especially if you're looking for some extra challenge.
I'm playing with a similar project and found Purist DI to be surprisingly tough. I assumed I could steamroll it with a Berserker, but time and again I just ran out of steam; those Dragon Guards take a lot out of you, both in health and in curses applied. The one time I picked up WONAFYT + Balanced Dagger, I couldn't find ENDISWAL or Binlor so I had to fight four of them--ugh. Finally got it with a Dwarf Rogue.
Goblin assassin worked for vicious vicious, but Waldo0 used his super secret strategy that he NEVER revealed (I think), so if he will finally reveal it ask him.
