Thunderclast Siege Suggestions
Next Friday, I’m planning to run a one-shot involving my players defending a city from a Thunderclast and Fused. My general idea is they’ll be tasked with defending an Oathgate from a Thunderclast sent to destroy it while fending off Fused and Parshendi defending the creature. I’m looking for advice on how some of you more experienced DM’s would run this in the Cosmere RPG system.
Parameters: I’ll have five or six players, and about half of them have Cosmere knowledge. All have TTRPG experience and I’ve run a DnD 5e one-shot for all but one of them. I’ve run Bridge Nine a couple times in the past for different groups. I’d like this session to last 2-3 hours.
Ideas so Far: They’ll start at the city wall, watching the approaching army, waiting for reinforcements to arrive via the Oathgate. They’ll see the Thunderclast rise and punch a hole through the wall, heading for the Oathgate. My players will be tasked with stopping it before it reaches there. Along the way, they’ll have to deal with Parshendi Soldiers, Heavenly Ones and Magnified Ones, and different scenarios of saving civilians or commanding defenses to get their Stormlight recharged. The Thunderclast won’t attack them until they reach the Oathgate, which will be the Zelda-esque “final boss room.”
My Questions: Has anyone run anything like this before? What level would you recommend for the players? How can I make this a fun experience for my players? Is there anything I’m overlooking? How can I ensure the players don’t kill the Thunderclast too early while also not making it feel like they aren’t doing nothing to it?
I plan to write this all in a Word doc and share it later on. I would appreciate any advice anyone could give! 🙂
