Full disclosure:- I was not able to jump into either session of the Diablo 4 open beta last month because I had personal commitments to attend to and quite frankly, I have not been all that hyped up for the game. With that being said though, I might still end up purchasing and playing Diablo 4 when it finally comes out on June 6 just to see if it was worth the wait.
For those of you out there who are more excited about Diablo 4 than I am though and have been thinking about how you can build your Barbarian, Druid, Necromancer, Rogue or Sorcerer, you can get a head start with the handy tool created by Redditor lowpoly_nomad, aptly named the Diablo 4 Character Skill Tree Planner/Calculator.
This handy tool mimics the look of the in-game skill tree and you can use your mouse wheel to zoom in and out of the skill tree, and click and drag to move it around. Left-clicking on a skill will add a point to it, while right-clicking removes a point. There is a reset button that lets you easily scrap a build and also a share button that will allow you to show your friends what you have planned out.
As of now, the planner covers pretty much just the basics when it comes to skills but lowpoly_nomad has said that they are planning to add in Paragon Board and other features such as weapon expertise in the future. Hopefully, they continue to update the planner once the game gets released as I am quite sure Blizzard will balance and tweak some skills.
