Last week, I talked about how damn good Diablo 2 Resurrected is. This week, I wanted to give you a great companion website: https://maxroll.gg/d2/
Maxroll is, in my opinion, the best D2R resource on the internet. You can do absolutely everything here. There are guides for almost anything you want to know about, giving you a quick and to-the-point synopsis of standard meta builds.
They have a Grail Tracker as well – a Grail being your attempt to eventually collect every item in the entire game. The tracker is clean and easy to work with, and has every option you can think of, from indicating that you found an Ethereal version to marking that the item roll was Perfect.
Additionally, the character planner is absolutely top notch. Setting up a test version of your character is incredibly easy, and you get the absolute best readout for your damage, resists, and more.
If you smartly listened to my recommendation and have been playing D2R, you should definitely check out Maxroll to increase your game knowledge and plan your characters!
