Content and licensing

The guide text written by Erzzy is made available under the Creative Commons Attribution-NonCommercial 4.0 licence. You may share and adapt it for non-commercial purposes as long as you keep attribution and link back to the source.

That licence covers the guide text only. It does not extend to third-party trademarks, game assets, or artwork, and it does not extend to the design and source code of this website.

Acceptable use

When using this site, please do not:

• use automated tools to crawl or copy the site at a volume that degrades it for other readers;
• republish the content commercially, or in a way that removes attribution or implies official status;
• interfere with the site’s operation, security, advertising, or consent mechanisms;
• use the site for any unlawful purpose.

Third-party links and embeds

The site links to external resources and embeds third-party content, including the source Google document, a Google Sheets spreadsheet on the Skills page, community Discord servers, and the official game site. Those services are operated by other people and are governed by their own terms and privacy policies. We are not responsible for their content, availability, or practices.

Advertising

Hosting and maintenance are funded by advertising. Ads are served through NitroPay, an Overwolf company. Depending on your consent choices and your location, ads may be personalised. You can review or change those choices at any time using the privacy and consent links in the site footer.

No warranty

The site and its content are provided “as is”, without warranties of any kind, express or implied. Strategy advice reflects the opinions and testing of its authors at a point in time.

Game balance, rates, events, and mechanics change frequently, and information here may become outdated, incomplete, or incorrect. Nothing on this site is official guidance. Decisions you make in-game — including spending real money — are your own.

Limitation of liability

To the fullest extent permitted by law, the operators and contributors of this site are not liable for any loss or damage arising from your use of, or reliance on, the site or its content, including any in-game outcome or expenditure.

Changes to these terms

These terms may be updated as the site changes. The effective date at the top of this page will be revised when that happens, and continued use of the site after a change means you accept the updated terms.
