Context: I am making a Dread Necromancer who has gone the route of the Necropolitan, so this might apply both when I use my turning, or when some stuck-up goody goody tries to get all up in my business just because I wasn't ready to give up on life yet! Well, existence, anyway... -coughs-
So, turning, per PHB, simplified: The cleric makes his charisma check to see what the max HD he can affect is. Then he rolls for the total HD affected. Starting with the weakest/closest, undead get the literal fear of a particular god put into them, and pack their bags.
Do intelligent undead (or otherwise, if applicable) get any form of saving throw against being turned, after the cleric has made their rolls? Will save, etc.
I'm familiar with a selection of pre-turning options, like Turn Resistance +X adding to your effective HD, and Bolstering Undead (although without significant optimization towards it, Bolstering yourself is probably less helpful than simply wishing bad things at the opposing clerics' dice rolls).
Or is it just cross your fingers and hope the cleric rolls low... and keep a wall of skeletons in front of you in case he doesn't ?
