75% of three 192-unit storage chambers would be near the high end of that, nearing 450.<br/><br/>Turning may help, and I'll probably have Sam use Substitute Domains the day before they head out to have the Sun domain's greater turning on hand just in case, but mind, he/she isn't all that great at turning the undead.  Five uses with a +2 charisma mod, as a fifth-level Cleric, due to that one Metaphysical Spellshaper level.  Against 432 zombies, that's not much.  I<em>did</em>have Sam pick up two scrolls of Command Undead, which can command any nonintelligent zombie without fail, but it would have to be a pretty damn badass zombie to have any real impact.  Even an ogre among human zombies may not be worth it.  A troll, a dire bear, a dragon, those would be more like it (on that note, what<em>kinds</em>of undead can we expect?).<br/><br/>So, who wants to just go down there and kick some zombie ass? :P
