As it stands how, Dreadmaster requires, not one, not two, but essentially three feat taxes (leadership, Servant of the Fallen, Skill focus Intimidate), with those taxes combined with the fact that well... Bane is dead this class will likely be gathering dust for the next 20 years until Bane returns. So instead here is my proposal:
While there's some things kept from Dreadmaster, there are some significant changes, one of the major changes would be that this would be a low BAB class to emphasize the fact that this is not a combat cleric as opposed to all of the various high BAB cleric PrCs we currently have. In addition, I bumped the summon cohort to a x2 per day use, the reason for this is that from my own personal experience the cohort has always been fairly weak for being a level 10 capstone, and a second use would make it a bit more useful without needing to directly buff the various options.Chaplain, Sect Leader, Preacher - Not sure on a name, those are just a few that came to mind.
