Blizzard has launched Diablo III Season 20, naming it Season of the Forbidden Archives. Many adventurers have come to learn how to use the power within the ancient nephalem artifact known as Kanai's Cube. However, none understand this power better than the equally celebrated and reviled Horadrim, Zoltun Kulle. Kulle was able to unlock and harness the power of the Cube like none before, leveraging its power to siphon and archive the energies of powerful items. With Season 20, players are invited to explore the power Kulle might lend to your fingertips if his experiments went unchecked.

Throughout Season 20, the slots in Kanai's Cube that allow you to equip three additional Legendary powers will not be restricted to their usual categories. Normally a player can equip one power each from the Weapon, Armor, and Jewelry categories but, in Season 20, players will be able to mix and match between all three! This might allow you to run two Weapon powers with one Armor power. Or perhaps you might choose to run three Amulet powers instead. The choice is yours, and we're as eager as you are to experiment with the new build opportunities this creates!
Blizzard began re-introducing previous Seasonal rewards in Season 17 to make them available to players who may have missed them the first time around. For Season 20, this means awards originally available from Season 8 are returning to the Season Journey.

That said though, Blizzard want to be sure that players have something new to aim for if you've participated in previous Seasons. With this philosphy if leaving no one behind, Blizzard aims to provide new End of Journey rewards as introduced in Season 17, with two new cosmetic rewards for those who complete the Season of the Forbidden Archives in its entirity. Check out this Teganze Warrior Portrait Frame and Bat pet!

As well as the Boots and Pants slots of the exclusive Conqueror Set, you'll also be able to win a series of portrait frames that smolder with demonic fires of the Burning Hells. The iconic "wings" of Andariel will also be available once more, allowing players to live in their inner Maiden of Anguish.
If you've been diligently slaying demons for the past few Seasons and reached Conqueror in the Season Journey each time, you will almost certainly gained a few extra stash tabs. You'll earn one additional tab each Season by finishing the Conqueror tier, up to a maximum of five:
Want to prepare your Conquest plan for Season 20? Here are the challenges you will have to overcome in Season 20.
For Curses!/Stars Align, pick any Cursed Chest event that requires killing monsters and defeat over 350 or more at level 70 on Torment X or higher. Push your way to Greater Rift level 75 to complete Divinity/Lionhearted. For the fiercest demon slayers, Boss Mode/Worlds Apart is a speed challenge where you'll need to eliminate the following bosses at level 70 and Torment X in under twenty minutes:
Finally, Years of War/Dynasty will be a great test for those who enjoy mastering various Class Sets, and if that's not enough, Masters of the Universe/Masters of Sets will challenge your tactical understanding of Set Dungeons.

Finally, the Class Sets rewarded for completing certain chapters in the Season Journey courtesy of Haedrig's Gift have rotated once more. Here are the available Sets below. For those new to Seasons, here's how it works:
Completing Chapters 2, 3, and 4 of the Season Journey will reward you with three of Haedrig's Gifts. Each Gift contains a few pieces from one of your Class Sets. Players can only unlock one Class Set in this manner per Season across Hardcore and Non-Hardcore, so choose wisely!
The set you receive depends on the class of the character you're playing when you open each Haedrig's Gift. To collect a full Class Set, you'll need to open all three on the same character.
Here are the sets granted by Haedrig's Gift in Season 20:
