| Eek. Good luck. The module says that it is based on the principle that 100th level characters aren't 10 times as powerful as 10th level characters. But that was true in past editions. In 3.X, 100th level characters are more than 10 times as powerful as 10th level characters. You'll have to really go wild to make a 100th level adventure.
I mean, consider a Half Red Dragon Marilith Fighter 20th/Blackguard 20th/Barbarian 20th. It takes hours to generate such a character. And she's still so weak that a 100th level character defeating her wouldn't even get XP. Even the ELH creatures are too weak. You're looking at using advanced infernals as cannon fodder. Ykes. |
