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.

Improvements​

• Items with capacity and usage values (e.g. Portable Flashlight) can now have their usage tracked in their sidebar.
• Items which require batteries can have them installed in their sidebar.

Bug Fixes​

• Added missing description text to Locus weapons.
• Fixed typo in the description of the Artificial Third Eye augmentation.
• Fixed the option to color HP on the Starship sheet not working.
