Our whole group had a lot of fun with this module. It's easy to run, easy to drop into any campaign and easy to prep.
It is a great module to get into the Halloween spirit. There is a ton of Halloween atmosphere and the final boss is fantastic! It has tons of really cool abilities including some great buffs that are possible for the players!
This module has a lot of roleplay opportunities and also a great combat encounter. There is also a good mystery to be unfolded but my players didn't really get to the bottom of that on their own before things popped off (they wanted to party too bad lol).
I DM'd this for my podcast and YouTube series so if you want to watch or listen to a playthrough you can check it out below or just search "One-shot Onslaught" wherever you download podcasts:
