I was thinking about how it would be fun to have a new challenge for the SPF. Taking on the ubers would be a great way of putting your chars to the test, as well as make for an interesting multiplayer experience.
Iv heard there is an uber mod you can find over at PK, but that it changes certain other things classifying it as a hack.
My idea was an uber mod that changes nothing but allowing SP characters to fight the uber bosses and the bosses drop nothing. We all know that the hellfire torch is imbalanced :cool:
Personally, since nothing else is changed at all, I dont see how this would affect trades and such. In the SP PvP FAQ i believe it states that RWM + RRM people can duel against vanilla players and the vanillas wont be tainted as long as no monsters are killed(thus no items obtained). I believe this uber mod would follow the same principle.
