Free Homebrew Content for Dungeons & Dragons 4e

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?

How To Be: Disney’s Robin Hood (in 4e D&D)

This month, I felt it was time to approach the challenge from a different angle, of taking something with an obvious, easy, simple solution and then exploring around that. And for that, we’re going to look at a classic character, a character who’s so well known we don’t even remember we’re referencing him when we…
