My ongoing campaign has hit the third tier of play, with characters from 13th to 15th level. The published materials that I've seen top out at 15th level. I started out using materials from published adventures, but have been mostly generating my own stuff for the past year.
Are there good reference materials for high-CR monsters (over 15) other than the ones in the MM? And are there good reference materials for high-level play? With ~2 years since release of the PHB, I can't be alone in needing high-level materials for my group.
In response to questions:
- There are 30 monsters in the MM with CR of 16 or greater. 16 of them are dragons. I know it's called Dungeons and Dragons, but some variety is nice.
- The monster creation guidelines in the DMG are useful for creating my own high-CR monsters, and I've used them. I'm looking for additional examples of high-CR monsters to use as inspiration. With a sample set that's 53% dragons, I don't think I'm getting a lot of perspective on what's possible.
- Creating high-level NPC characters is a bunch of work, especially for spellcasters. I'm willing to make that investment for characters that matter, but if I'm going to have an incidental encounter that I want to be challenging for this party, I either have to forego using humanoids or spend time on them.
