Daeva Companion (unofficial) — companion for AION 2

A fan-made companion for AION 2. Today it is the leveling guide for the Asmodian Assassin, Lv 1 → 45: what to do next in the story, which regional quests are open, Sealed Dungeons and strongholds by level band, skill points, Daevanion boards and stigmas. Free-to-play focused. Data is cross-checked: two independent sources, game-database values or the maintainer's in-game screens; anything weaker is labelled single source, inferred or disputed in the app's Confidence card. Game data changes with patches, so check in game. Progress is ticked by hand.

Unofficial and fan-made: not affiliated with or endorsed by NCSoft (NC Corporation) or NC America. AION and AION 2 are trademarks of NC Corporation; game names and images belong to NC. Most game data comes from Metabot; every source is credited in the app's Sources card and in data/DATA_SOURCES.md. Listing a source doesn't mean it endorses this guide.

Using it

• Basic / Advanced (top right): Basic keeps only the essentials.
• Next up always shows your next move. Space / Enter completes the top card; arrow keys move through the stack. Pop out opens it in a small always-on-top window (Chrome / Edge).
• Level up in the Journey card is the only thing that changes your level; ticking quests never does.
• Works offline after the first visit and can be installed as an app (browser menu → Install / Add to Home Screen).

Your progress

Progress is saved in this browser only (localStorage), never sent anywhere. Use Export progress in the footer to save a .json backup and Import progress to restore it (the previous state is kept one step back). See PRIVACY.md.

Moving from the claude.ai version

The guide was first published as a claude.ai artifact. Browsers keep each site's storage separate, so your ticks don't carry over by themselves:

1. Open the claude.ai version and click Export progress (footer). Allow the download when asked.
2. Open https://daevacompanion.com/ and click Import progress, pick that file, then Replace.

Both versions use the same save format, so this works in either direction.

Development

Requirements: Node 22+. No runtime dependencies; dev dependencies are esbuild (bundles the app's modules into the single-file page), ajv (validates the data against data/schema/) and Playwright (tests).

npm ci                                   # once
npx playwright install --with-deps chromium   # once, if you don't have Playwright's Chromium yet
npm run build                            # dist/ (the site; the claude.ai artifact is frozen and not built)
npm run serve                            # http://localhost:8080/
npm test                                 # build, then every suite against dist/ except perf (≈10–15 min)
npm run test:quick                       # build, then the suites with a smaller regression matrix and no screenshots
node tests/run.mjs --only e1,save        # selected suites (after a build); --shard journey: one CI shard
npm run test:perf                        # build, then the non-blocking update() < 15 ms timing suite
npm run gen                              # validate data/**, run the cross-record checks, rewrite data/DATA_SOURCES.md
npm run test:data                        # schema suite only (no browser, ≈1 s)

src/index.html          the page shell (head + markup); the build inlines the styles and scripts it names
src/styles/*.css        styles (fonts.css: the @font-face rules; app.css; brand.css: header lockup), inlined verbatim
src/main.js             the app script (ES module entry), bundled by esbuild into one inline <script>
src/data/*.js           the data tables under their page names (compiled from data/, plus what stays code) and the text helpers
src/site.js             the standalone site's own script (storage persistence, service worker)
src/assets/             icons and self-hosted fonts
brand/                  the brand's source SVGs (icon, maskable icon, favicon, wordmark); tools/brand/ draws them
src/sw.js               service worker template (offline cache), filled in by the build
public/                 copied to the site root: CNAME, robots.txt, sitemap.xml, 404.html, favicon, manifest + icons
scripts/build.mjs       builds dist/;  scripts/serve.mjs  local static server
data/                   the game data and guide text in format v2 (docs/DATA-FORMAT-V2.md; schemas in data/schema/) + DATA_SOURCES.md
tools/gen/              data generator (gen.mjs: validates data/ and compiles the module src/data/generated.js at build time)
tools/research/         the scripts that built the v1 data files (provenance)
tools/history/          one-time patch and conversion scripts (E2 / E4 passes, the v1 → v2 conversion; provenance, already applied)
tests/                  Playwright suites, fixtures, baselines (old app versions for migration tests), runner
docs/                   ARCHITECTURE.md, ISSUES.md, DEPLOY.md

Read docs/ARCHITECTURE.md before changing anything that touches saved progress, and CLAUDE.md for the working rules. Deployment: docs/DEPLOY.md. Known gaps: docs/ISSUES.md. History: CHANGELOG.md.
