I was thinking about spelljammer again and realized I should share my house rules for sphere generators.

Here's a PDF for home printing

I wanted there to be more playable material for spelljammer. So I made this horrific dungeon heavy on cosmic horror metamorphosis that doesn't feature mindflayers.

Here is a pdf if you wanna print it.

And a plain text version.

Edit: I've not cleaned it up and provided versions for mothership and dungeon crawl classics.

I wrote a cleric spell for spelljamming clerics in DCC and technically a spell for wizards but honestly this is just a spelljammer generator alongside a spelljammer randomizer. This document assumes you have access to the spelljammer boxed set already.

If you want to download these as pdfs these can be found here.

Special thanks to Blark and Sean.
