Ok here is a thought from me,
we allow deathslayer7 to get his rouges at whatever his CR # of people was, because dragonsbreath arrows are nasty against everything from siege weapons, food supplie, tents, even any gun powder they may have. I can spend the remaining of my gold on poison destribute it among his rouges then whatever food they don't burn they can posion.
Just a thought and that 300 CR level cap kinda hurts. but I think if you allow us to do this then we can do some serrious damage. As for the assassination attempts Deathslayer7 and myself can attempt to handle those. We would just need descriptions of targets and where they might be in the camp.
edit - this also means that I relinquish my 50 CR worth of people.
