Posted this in the dms_corner community, and figured yall might have some input.
Alright, I know I don't post--like ever, in fact--but I need a bit of help. I've got a massive dungeon to build, and I'm running out of ideas for creatures. Well, not running out of ideas, but running out of creatures, more like. I'll explain behind the cut, as I tend to get longwinded.
So I generated a huge maze (fills an entire notebook sheet of graph paper), blocked in certain parts to make buildings, and created a huge, labyrinthine city that I never thought I'd use. I was horribly wrong, because in a fit of creativity/unthinking masochism I looked at it and said, "This would be perfect for the next long arc of my campaign." So I divided it up into sections (relatively easy, as mazes tend to do it naturally), themed them, and am done with the first seven. The eighth is sticking me.
The story is that this whole thing was once the main district in a grand city ruled by mages, and was thrown down in a huge version of the imprisonment spell, the mages ruling each section turned to stone, and their creations magically bound to their areas in the city to further prevent escape. The players will have to head down there in classic style--they know a duke, who has a young daughter, who will be kidnapped by an inexplicably escaped monster (I'm thinking about a big, nasty ogre mage with some levels or templates) that brings her down into the farthest depths of the city, leaving a note (of course) that gives the Duke a month to face him and get his daughter back. The party has managed to impress the Duke many times before, and being his new favorite swordarms, he's going to send them.
This dungeon starts at level 7, and by section eight the party will have just hit level 10. The theme for this section? Bound outsiders. I've been looking through lots of outsiders at CR 9-11, and I shouln't have a problem filling the five sections before the boss--suggestions are welcome, though. I need a boss for the last section, one that would be the prize of a very curious binding wizard whose spells still linger long after his petrification. What I was thinking was mixing things up a bit in terms of outsider encounters: a formian armadon fighting alongside a blue slaad, angels forced to aid demons, that kind of thing.
Well, I thought, wouldn't it be cool to make some kind of half-fiend celestial (or vise versa), as if this wizard was twisted enough to force such creatures to breed? I know it's not technically allowed, but I'm invoking DM rights and doing it anyway. Problem being, I don't want to kill off the party (there's a neat crossbreed on the WotC site, but it's CR 17). So, know any good CR 8-10 fiends or celestials that would make good half-breeds? Setting is not an issue, and I have access to pretty much any book. Suggestions?
I was thinking of using a Movanic Deva, making it a half fiend, and making it completely nuts. However, I would like something a bit more combat heavy, less spell-oriented.
When I'm done making this dungeon, I'm going to write it up and post it in my journal, if anyone wants to see it. Still a lot to get done, but it shouldn't take me too much longer. Thanks, in advance, for any help you can provide. Rock on.
