MCDM, Matt Coleville’s company, just released Flee Mortals! This 400 page book includes new takes on existing 5e monsters and a few brand new ones – all in MCDMs style of cool tactics and action-oriented designs. I had the great pleasure of designing the vampires in this book including the monstrous Count Rhodar Von Glaur!
Check it out!
I’m in the exact same boat. I’d like to use some of the monster lore and trying to convert the action oriented bosses to be used in PF2e. I’m thinking it would be pretty easy to just treat the Villain Actions as costing two actions in Pathfinder. I think the minion rules would transfer over as well.
I expect the easier approach is going to be using the PF2e custom monster rules to create something which matches the theme of the monsters in the book due to how different Pathfinder math and tactics are. But hopefully it at least gets the creative juices flowing. I really like MC’s style in general so I’m certainly not upset, just a bit disappointed.
