Homebrew As mentioned above, this release adds the first part of the Homebrew feature allowing you to create custom content in Hephaistos. Currently, this only supports Feats, but the plan is to support everything. Next up, I will be adding support for homebrewing equipment, starting with weapons.

Part of creating homebrew is being able to apply mechanical effects (numerical bonus to skill checks, granting a feat, and so on) and this is done in Hephiastos 2E through a bespoke scripting language called "Dragonscript". This release also adds documentation for Dragonscript (aka Dragonscript 2E, since it's been rebuilt for the second edition system). Like Hephiastos 1E, I do eventually plan on adding an infosphere so you can easily find IDs and examples, but in the mean time I'm happy to help with that stuff.

Galactic Ancestries The next major Starfinder book Galactic Ancestries is coming out later this week and I just wanted to mention that I will be focusing on adding content from it into Hephaistos. Most of the content should be in by the next Hephaistos release (13th April), and all of it should be in by the release after that (27th April).
