So, I’m trying to build Icespire Hold for the climax of my dnd group’s adventure. I had to make a few small concessions so far to fit what tiles I got in the Rampage bundle. Currently I’m looking for a single triangle piece to make octagonal based rooms. Larger scale would work with the tiles I have, but it would offset the build which I’d prefer to avoid. I thought of using the curved tiles as well, but it comes to a similar spacing issue. Does anyone know if any of the sets have a singular diagonal piece, and a matching wall section? Attached is an image of the area I’m trying to create.
