My group had a blast running Breaker of Chains and I had a very easy time prepping and running it. My group played through the module pretty smartly and ended up with zero casualties (4 level 6s). This is definitely a fun module that can be dropped in nearly any setting/campaign if you need a quick, one session dungeon crawl that is easy to prep.
You can watch our full-length session of the module here. It took us one hour and 53 minutes to complete (they missed a couple of rooms, made quick work of the boss and started the session right outside of the prison from a previous session)
