I want to run a one shot of a party of 5 20th level PCs versus a powerful dragon in its lair. While I have been running (and designing for) 5E for all of its life, I have never run 20th level before.
A few context notes:
PCs will be custom built for the fight, with access to PHB, Xanathar's and Tashas.
It will be one shot without a lot of story, focused on the tactical experience.
It will be played on Fantasy grounds, using a grid, line of sight, etc.
The experience I am going for is very difficult but fair, and fun.
My biggest concern is action economy. I am thinking of combining minions with terrain to make sure the PCs can't just gang up on the dragon.
Thanks for your help.
