I came to a similar conclusion in our confrontation with the Deemers at their camp. Due to the fervor with which they fight, they are... particularly difficult to subdue.

[And they didn't really seem to be interested in anything but absolute victory or absolute defeat. One had even sacrificed himself to allow Miz Poppy to escape... It was a difficult enemy to face.]

I don't believe we have any other option currently, but I will be... very curious as to what answer they might have to this, if any.
