Class vs class? And 100k per character or per person? And what if all my characters win, will they meet each other in some final? And can you stealth > sap > /dance?
Same class fights, so each base AC fights within that group. e.g. Sage vs. Sage, Sage vs. Sorc, Sorc vs. Sorc.
100k per character.
Stealth > sap > /dance allowed yes
No final unless people want to do it, don't really see how it can work considering some classes are much much better 1v1.
