Yes, although it’s a fairly minor difference of a few words, and the confusion over never bound, unbound, bound…I wish the terms were clearer, but it’s the wizard’s fault.
What they thought was that it was a “minor never bound demon”
If it had ever been previously bound, they would have recognized it as a demon and have been able to get a better handle on it’s power level and if it was currently bound to someone (with a bit more work, Lenamare would have shown them how to see the binding and see if it was frayed or still connected to a master: like in the bar in the courts).
So anyway, what they thought they saw was what appeared to be a minor never bound demon. And so they adjusted tactics to get that, and then it fought back harder than expected and they had to seriously up their game and the level of the spells they were using.
