I require a prestige class that gives me cool abilities for my Cleric/Ruby Knight Vindicator/Crusader. I'm going for 9th level maneuvers, which means I need at least 1 more crusader level, and I'm probably going to delay RKV for a few levels so I can pick up the last 3 levels or so at the same time for maximum high level maneuvers. So far, build looks like Cleric4/Crusader1/RubyKnightVindicator2 (took Crusader first then went straight cleric). High BAB a plus, Dipability a real turn-on. No Complete Champion. A) I don't have Access to it, and B) I think it's far too cheesy. Prestige Paladin is on the list, if only for the pretty sweet and cheap mount upgrade, although the mount's not all that strong it's still nice, and there's no reason not to dip it. Character is Lawful Good, so a foray into Church Inquisitor looks nice, but I'd like some more suggestions.
Role I'm looking for is main Healer/Support magic/Battlefield control, with loads of Tanking interspersed into the build. I messed up and didn't pump Dex, but I was running really low on stat points, so AoO builds are out. As it stands my spell progression and maneuver progression is fine, I just want some cool class features!
