How much work would be involved in converting an entire AP to P6? Does P6 break down when you're converting CR18+ monsters?
I'm thinking of doing Iron Gods as P6 or even converting it to Monte Cook's Numenera system (the Cipher system) and I'm trying to get a handle on the work necessary for each.
Thanks!
Its going to be a lot of work in the last few books of any ap. It isnt just a matter of shifting numbers on statblocks. Many times there are specific abilities the party needs access to that are trivial or at least easy for a higher level party, that a P6 party simply wont be able to do. Pathfinder above like level 14 is a completely different game. P6 is like game of thrones or lord of the rings. 14+(the end of APs) is Justice League
In some cases you might be able to just swap out one set of monster stats for another such as using a young green dragon in the place of an old green dragon or reskinning ogres as giants. In others you might need to basically need to strip things down and build your own custom monster. Doing that sounds like almost as much work as building your own campaign, but I guess if you like the story and dislike high level gaming it might be worth the effort.
