I sure could use some help putting together worthy challenges for some level 20 players. Most of my other games only end up at level 5, so I am over my head. If you have experience with level 20 3.5e stuff, please PM me so I can run some ideas off you. If you're interested in DMing with me that's even better.

A little more info:
Our aim is to have the six players:
One Hexblade
One Ranger
One Paladin
One Soulborn
One Divine Mind
One Sohei


As the soulborn said, "I think it will be easy to challenge our characters. Just throw us a sorcerer or wizard of the same level. Still... we may have a few surprises. I bet that noone dared to experiment with only these classes. Are our classes that low tier? Only one way to find out and maybe our GM will have to throw us something much worse than just a 15 level wizard. :D
