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).

I want to take a moment to address the various performance and instability issues Hephaistos 2E has had in recent weeks. Firstly, apologies for any inconvenience the long (sometimes infinite) load times, website crashes and other related issue caused. Secondly, thanks to everyone who reported these issues. Finally, between the last release and this one I have implemented various infrastructural improvements that should prevent similar problems from occurring in the future, and I have plans for a few more in upcoming releases to ensure that using Hephaistos remains a smooth and responsive experience.

Between the last release and this one I've updated a significant chunk of the infrastructure on which Hephaistos 2E is built.

If you encounter any "weird" behaviour when using the website, like the interface not updating properly or buttons being the wrong color, please let me know.

2025 In Review​

This is the last Hephaistos release of 2025 so I just wanted to take a moment to reflect on everything that happened. Of course, the biggest Starfinder-related news was the release of the second edition. Certainly, the last half of this year for me was dominated by updating all the content of Hephaistos 2E, and also starting to add content from Pathfinder source books. Hephaistos 2E also saw the addition a Companion buidler (as part of the Character sheet) and a Creature builder based on the rules in GM Core.

Hephaistos 1E also continued to receive major updates, including a Charter Manager and a Changelog, in addition to the usual minor improvements and bug fixes.

On a personal note, it was also very exciting for me to get the opportunity to actually contribute to Starfinder 2E and write the Skreesire and Skreeling for Alien Core.

Looking ahead, there's obviously a lot of features and content to add to Hephaistos 2E, and I also want to finish off the few remaining items on the Hephaistos 1E roadmap.

Thanks to everyone who used Hephaistos, recommended it to others, reported bugs, provided suggestions and donated money for all your support. Knowing that Hephaistos helps more people play Starfinder is genuinely one of the most rewarding parts for me.

• Fixed Operative specialization Striker still providing Strength as a possible key attribute.
• Rogue's Thief racket now adds Dexterity modifier to damage rolls for finesse weapons if it's higher than the Strength modifier.
• Fixed High attribute modifiers in the Creature builder being 0 when they should be 10.
