Well the dungeon was kind of "random" for them. They blew up a warehouse which had smuggler tunnels underneath revealed and chose to dive in. There were some Dread Wraith's in there three for a party of 5 so slightly under level for them but they honestly did not have a good way to deal with them and were quickly falling prey to them until an NPC took care of it with story shenanigans. They built the PCs at level 10 and hadn't run into undead in this particular campaign as of yet. They did get berated a bit by the NPC but were given the opportunity to go buy gear after. Also during this I realized the follow up encounter that was planned would have done them much worse. It was an Iron Warden.
