About Gacha Codex

Gacha Codex is an independent strategy hub for the most-played gacha RPGs. We publish tier lists, character builds, banner coverage and boss strategies for Wuthering Waves, Zenless Zone Zero, Honkai: Star Rail, Genshin Impact, Neverness to Everness and other live-service gacha titles — updated daily.

We are an independent project. We are not affiliated with any game studio or publisher, take no money from developers, and have no review-copy or early-access arrangements. Every recommendation on this site is based on public information any reader can verify.

What you'll find here

• Weekly-updated tier lists covering every released character across the games we track, with the reasoning behind each placement.
• Character build pages — recommended weapons, relics, light cones, teams and rotations, sourced from official patch notes and established community testing.
• Boss strategies for endgame content.
• Long-form guides on rerolls, banners, pity systems and game economy.
• A growing FAQ on gacha mechanics that recur across games.

How we make this content

We are transparent about our editorial process because it's the only way readers can decide whether to trust what they read here.

1. Structured research. Each article starts from a machine-readable data shape — a character's skill set, banner schedule, boss attack patterns — pulled from official patch notes, in-game data and established tracker communities (HoYoLab, Prydwen, Mobalytics, Game8 and others). Sources are recorded with each article.
2. AI-assisted drafting. We use large-language-model tooling (Google Gemini and Anthropic Claude) to draft prose from that structured data. This lets a small team cover more games with consistent depth. We disclose this because Google's own guidance — and ours — is that AI-assisted content is fine when it serves readers, is fact-checked and is honest about the method.
3. Multi-pass quality checks. Every draft passes a QA layer that scores it on six dimensions: search-intent match, information density, structure, factual accuracy, originality and SEO hygiene. Drafts that fail on factual accuracy or contain unsourced specifics are rejected before publication.
4. Publishing gates. Only articles that meet a minimum quality bar are indexed in search engines. Articles below the bar are either rejected or kept noindex'd so they don't dilute the site's signal. The full rubric is in our Editorial Policy.
5. Reader feedback loop. Comments and contact-form reports are moderated and acted on. A reader-flagged factual error triggers an article re-check.

What we don't do

• We don't publish leaks. No datamined character kits, no unannounced banners, no pre-release content. Coverage starts when the developer publishes the information.
• We don't paywall guides or sell reader data. The site is free, has no login, and runs on a mix of advertising and affiliate revenue — both disclosed.
• We're not the official wiki. When the canonical answer to a question lives on a developer's site or an established community wiki, we link to it instead of rewriting it.

How we make money

Two streams, both clearly marked:

• Display advertising via Google AdSense. See our Privacy Policy for cookie and ad personalization details.
• Affiliate links on a small number of articles where peripheral or gear recommendations are part of the reader's question (e.g. "best controller for HSR"). See our Affiliate Disclosure for the full list of programs and how editorial independence is maintained.
