[sblock=Leif]Definitely nothing new for me to be confused, but in this case it might be justified . . .
Thea cast Whelming Blast, which does non-lethal damage to the critters. Her feat gives them a -2 on attack rolls and -1 AC. It does nothing to shift damage from SoulFetter to them. That particular nasty little effect is due to the Vestige currently bound to SoulFetter.
Here's the passage from my post on 09/19 at 5:55 AM (Post 568):
Using the Shield Self ability granted by his currently bound vestige (Dahlver-Nar). Designated target must (since it would be unwilling) make a Will save (DC 13) or SoulFetter shares any damage he takes ½ and ½ with it. This effect will continue as long as the designated target is within 30' of SoulFetter, and regardless of the source of the damage to the Binder (in other words, even if the other critter hits him with a javelin, the designated target will take ½ of the damage and Soulfetter will take the other ½). The target creature will feel a tingle/hostile effect but will not necessarily know the source of the attack. (Tome of Magic, pg. 19 & pg. 28).
I didn't see a Will Save post anywhere, so I'm guessing SoulFetter's action was missed completely and it's possible Frick (or Frack, whichever the heck he is) will make his save and SoulFetter will take the full 4 points . . . But maybe not.[/sblock]
