Hi all! I'm currently beta testing a new CR 17 monster. I ran it against a party of 17th level characters, but now I'm wondering what the next playtest should be.
1) Run it against 15th (or 14th?) level characters, to see how they fare against a potential boss?
2) Run 3 of them against a 20th level party?
3) Run 12 of them against a 20th level party, for a truly epic encounter?
Okay, probably not the last one. But you get the idea...what do you think is the best test of a monster's utility?
Cheers!
I'd probably go with the APL 14 party. CR 17 monsters are generally boss monsters rather than basic encounters (unless you run a LOT of mythic/epic type games).
