So I am trying to create a mob for my Homebrew game where an Ancient Green Dragon has mated with a Succubus. Everytime I play test the boss (CR15; Merge between Adult Green Dragon and Succubus), it murders a party of 4-5 level 10-12s. Anyone ever merged these two or can give me some assistance?
Could you post the stats so we can take a look? In general, a CR 15 monster with legendary actions is supposed to be a solid challenge for 4 12th-level PCs, but that could vary based on the build.
