Terms of use

Ancient Lab is an independent, fan-made reference for Dota 2. It is not affiliated with, endorsed by, sponsored by or associated with Valve. Dota 2 and all related names, logos, artwork and in-game assets are the property of their respective owners and appear here only to identify what each record describes.

Using the site means accepting what follows. If you do not, the remedy is simple: stop using it.

Everything here is provided as is, with no warranty of any kind. Values change between patches, and the data here is a snapshot from the date it was collected.

Unknown values render as a dash rather than a guess, and recommendations are marked as ours. Read where the data comes from to see which is which. The planners — matchups, drafts, builds and the rest — are models built on that data, not readings from the game.

No liability is accepted for any loss arising from acting on what you read here, in game or otherwise.

• Read it, use the planners, and share the links they generate. That is the point of them.
• Quote figures elsewhere with a link back. A credit costs you nothing and helps someone check the source.
• Do not scrape the site at a rate that degrades it for other people, and do not republish it wholesale as your own.
• Do not use it to build anything that breaches Valve's own terms.

Game assets shown here are not ours to license. Their owners' terms govern them, whatever this page says.

The site is free and run in spare time. It may change, break, move or disappear without notice, and pages may be rewritten or removed as the game changes. Links out to OpenDota, Steam and other sites are provided for convenience; what happens on those sites is governed by their own terms, not these.

The site carries advertising and uses analytics to understand which pages are read. What that means for your data, and how to opt out, is set out in the privacy policy.

These terms can change; the date at the top moves when they do. Corrections, takedown requests and anything else go through the contact page — particularly corrections, which are the fastest way to improve the site.
