Just played this and on the one hand, it was a good module, stretching people's role play skills to try to get some things done. That was really good.
The downside is that the fights are way out of control. Granted, we were a table of 4 playing high, and the middle fight was not too brutal. But the final combat is just horrible. Without a proper table balance, you will auto-fail, even if you have done everything right. Spoilers for the final fight below.
So, overall, I like the idea of the module, but the execution needs work. If you want to play this, make sure you have a full and balanced table.
