User blog comment:FauxCerf/Treehouse of Horror XXVI Event - The Third Act/@comment-26561761-20151109041431

Two observations:

1) Formless Terrors never dropped

2) Today fighting M'nthster at the campfire I got a 9 damage (same fighters as usual), so it would seem EA did some changes to the damage the kids could deliver, especially when you consider that I don't have any of the premium skins.
