I am trying to fit one of my PC's backstory in to the AP. He is a swashbuckler that has been looking for his master for the campaign and eventually spotted him in fort rannick right before Lucrecia used dimension door to bring her and his master to hook mountain peak.
My thought is to make his master a frost wight just like Lamatar and have them fight both (5 PCs). However, Hero Lab is saying that this is going to be a CR 14 encounter. Is this going to be too much? Are there other adjustments I need to be making? For reference, I currently have given his master 4 frost wight levels and 7 swashbuckler levels.
