This was my first experience playing a module with multiple tables and it was fantastically fun. Some feedback if you're planning to run it:
- The module runs longer than 4 hours. Even after the DM did a lot of narrative handwaving at the beginning to shorten the visit with SEER, it took our table 4.5 hours to complete the module.
- Bad Fruul is one tough cookie. Of the three tables, two beat him and one suffered a TPK. This felt about right--you had a good chance of succeeding but faced real risk.
- The siege points mechanic does a good job of abstracting events to keep things moving. Occasionally I felt like it robbed the players of agency. For example, I wanted to scatter caltrops during a battle, but the DM explained that was already factored into the siege preparation.
- The need to manage resources fighting wave after wave heightened the dramatic tension.
tl;dr: We loved it, and Parnast Under Siege is a thrilling season capstone.
