There are "corpses" of Scarlets at the beginning of these dungeons. They're not actually dead, though. In fact, it's very possible to be put into combat with them, and unless you give them a true death, you'll be stuck in combat for the entire instance. They grant XP and loot when you kill 'em for real.
Herod was immune to my Consecrate all the time, not just during his whirlwind.
There's a mix of level 33 and 38-39 mobs in the Cathedral proper, which seems odd.
Edited this thread to include Cathedral.
Edit number two: Mograine and Whitemane are also immune to Consecration, so I guess it's a big with bosses being immune to Consecration rather than an SM specific bug, sorry.
