First launch
These builds are not code-signed yet, so your system warns you once.
- macOS: right-click Borealis in Applications and choose Open, then confirm.
- Windows: in the SmartScreen dialog choose More info, then Run anyway.
- AppImage: mark it executable (
chmod +x) and open it. - Android: open the APK; Android asks once to allow installs from that source.
What's in 1.0.0
- Build characters step by step: race or species, class, background, ability scores, proficiencies, feats and gear, levels 1 to 20, multiclassing.
- Spellcasting for every caster, including a wizard's spellbook and daily preparation.
- Printable PDF character sheets: colour or ink-saving, fillable or flattened, Letter or A4, with spell pages and cards.
- Import Aurora Builder XML content and
.dnd5echaracters, your own homebrew, and your own local 5etools data. Every import shows a preview first. - An optional assistant that runs through a command-line tool you already have, off by default and desktop only.
- No account, no telemetry. Characters are plain files on your device.
