So this is the bit I’m really interested in? What are the unique elements that make Spelljammer special.3.) Spelljammer is more than ships: There are a lot of lore elements of Spelljammer that are unique and different. It feels like something unique when you really dig into it, or when you develop your own version like I have. There are major elements of my campaign that are highly influencd by the way I use Spelljamming, and they are amongst the most iconic elements of my homebrew. I have distinct factions, persaonlities, and long storylines that are based around Spelljamming and the influence it has on the setting.
