Free Homebrew Content for Dungeons & Dragons 4e

The Square Fireball is a place for Invincible Ink (otherwise known as Fox and Talen Lee) to develop and share our homebrewed 4th Edition Dungeons & Dragons content.

Here you’ll find new content, ideas, fixes and houserules, and whatever other content we decide to produce. Sometimes we’ll be back-porting things we like from newer editions, or bringing back something from yore that didn’t quite make it into our favourite version. Sometimes we’ll be bringing something entirely new that doesn’t fit as core content of our self-contained campaign settings, like Skies of Escarnum.

Why 4th Edition? Because that’s the one we love. Mostly this is just stuff we’ve made for our group to use, but why not share it with the greater 4e community since we can?
