If you're stuck on how to design a map, give Bing image creator a try. I was pleasantly surprised with some results I got

I’m not a DM and I’ve never played DND so maybe this sucks but I thought I’d pass it on because I like browsing this community.

I was messing around with Bing Image Creator and thought I’d see what kind of map I could make. I think my immature prompt here was “The Ball Zone: Dungeons and Dragons battle map of a ball factory. Balls are used as obstacles throughout the map”

I’m not sure if I’d use anything Bing makes as-is but it might be cool for inspiration at least
