It's really the ultimate challenge in the D&D realm. There is nothing else out there. No other game, definitely not the newest release, and no other Baldurs Gate 2 mod either. SCS simply doesn't cut it if you are looking for a challenge.
I uploaded a few videos here if anybody wants to have a taste, the mod is called Improved Anvil:

>Kangaxx
>Another Lich
And this is considered a challenge? They're both completely neutralised by Protect from Undead scrolls. Then you just use Breach and Pierce Magic and wack them to death.
