Actually, followup for the "so how does that help folks vs deathward if they're a PM vs Sorc":
Haunt level*2 applied as per Augment summoning feat, only to created undead, SLAed, or charmed undead.
+16-20 to all stats over and above augment+the destiny one might make em last long enough to survive a room. (and they don't right now. As absurd as +8 total stacking HP and fort not being enough, they still die horribly.)
Simple enough to throw in before We have to wait half a year?
