So, I've been GM'ing a game almost since the day Black Crusade came out, we went through a bunch of stuff before hand of corruption came out, then ran through that with the same party. Effectively all of the characters should really be spawn and/or ascended at this point and beyond the normal scope of play. BUT everyone wants to keep playing from a perspective of "well, we just accomplished this great feat, have a planet of our own to command, and want to be gods".
So, the supplement "tome" books have been pretty useful so far, but I wanted to get some addtional input from you guys on how to approach this. Infamy allows an excessive number of rerolls at this point and feels like it may need reworking, but at the same time such characters should remain powerful. On top of that, while these characters are very powerful, they aren't all Commanders and need some way to remain relevant at the head of an army.
Any thoughts? Currently the party consists of a human psyker with lots of exalted psychic powers, a Chosen Berzerker, a Champion (very commander-ish), and a Heretek.
