How we work
The numbers on this site are estimates. Prices move by the minute, xp rates depend on the player, and drop chances are just that. We check game facts against the game itself and the community wiki before publishing, and we fix mistakes when they are pointed out.
There are no accounts, no paywalls and nothing to sign up for. Every tool works in your browser for free.
