On the third pile of treasure in the large room location, I would kill the first set of enemies that run towards Pagsly and then nothing would happen. It’d seem like Pagsly was frozen in place and wouldn’t search.
I noticed the waves of enemies not coming after the first one. I saw there was a group of kobolds roughly in the center of the area on the 3rd search that were being affected by the Zekvir influence.
I aggro’d the group of kobolds that were frozen by the Zekvir influence, they came towards me and I killed them. After killing that group, Pagsly finished his search.
I think the issue was that the next wave of enemies got stopped in place by the Zekvir influence and that’s what’s actually breaking it, not Pagsly being broken directly.
Not sure if this will work for anyone else, but it’s what worked for me.
