The lords of Hell await your return, traveler.
Countless demons have met their timely demise at the end of your weapon, yet their onslaught doesn’t relent. Sanctuary needs its savior! Return on February 22 to wreak havoc among the Burning Hells’ ranks in Ladder Season 6!
Ladder Season 6
Our previous Ladder Seasons for Diablo II: Resurrected have showed just how adept adventurers were at saving Sanctuary, racing to be the first to cement their names on the Leaderboard, while striking fear into the tormented hearts of their demonic adversaries in the process.
Ladder Season 6 will usher in a fresh opportunity for brave adventurers to race to Level 99 and amass powerful loot along the way.
Ladder Season 6 Launch Timing:
North America February 22, 05:00 p.m. PST
Europe February 22, 02:00 p.m. CET
Asia February 23, 10:00 a.m. KST
As with previous seasons, Ladder Season 6 will feature different modes:
Version Description Pre-Expansion Ladder The standard version of Ladder play that encompasses only the original four acts. Pre-Expansion Hardcore Ladder The hardcore (only one life) version of Ladder play that encompasses only the original four acts. Ladder The standard version of Ladder play that encompasses five acts, as it includes the “Lord of Destruction” expansion content. Hardcore Ladder The hardcore (only one life) version of Ladder play that encompasses five acts, as it includes the “Lord of Destruction” expansion content. For those new to Ladder Seasons, you might be wondering what happens to your Shared Stash loot once the current season ends.

Once Ladder Season 5 ends, all Ladder characters will be transferred to their respective non-ladder group. All items in that character group's Shared Stash go into a new Withdraw Only set of Shared Stash tabs, denoted by a check marked Past box. Any items from Ladder Season 4 stored in the Withdraw Only tabs will be lost at this time. You will have all of Ladder Season 6 to withdraw any items you would like to keep from Season 5. When Ladder Season 6 ends, this withdraw only set of Stash Tabs will be overridden with any items in the Ladder Season 6 Shared Stash. Be sure to get any items out before then or they will be forever lost!
May your Ladder race be filled with fiends to eviscerate and bountiful loot.

Patch 2.7

On May 2 at 10:00 a.m. PDT, a variety of feature adjustments, quality-of-life updates, and bug fixes will go live with Patch 2.7.
Feature Adjustments
Players will now have 4 additional Character Slots available across all Online Modes. The first time a Ladder character from a previous season is used in a non-Ladder game, the ability to Reset Stat and Skill Points at Akara will be reset. Characters from previous Ladder seasons who have already been used in non-Ladder games are ineligible. All Chat Lobbies have been outfitted with an automated system which will remove malicious messages from those conversations. Quality-of-Life Updates and Bug Fixes
Gameplay
The Next Hit Delay system now only applies to missiles created by casting the same skill. Each Assassin Martial Arts charge-up skill trigger is treated as a different cast of a skill for Next Hit Delay purposes. Knockback has been removed from the Bul Kathos’ Sacred Charge 2-Handed Sword. Druids are now able to shapeshift directly between their Werewolf and Werebear forms. The Assassin's trap skills now benefit from +% To Elemental Skill Damage modifiers. Fixed an issue where Mephisto would drop from lower-level treasure classes when Terrorized. Fixed an issue where an Assassin dying with Martial Arts charges active could cause a crash in Offline play. Fixed the issue where the Assassin's traps weren't benefiting from resistance reduction in Offline play. General
Fixed a translation issue for the Reached max character limit text in Polish. Fixed an issue where progressing between towns and connected zones from Acts II, III, and V would cause an abrupt lighting change when terrorized. Fixed an issue where the icon to denote a monster is Terrorized wasn't properly displaying in certain languages. Fixed an issue where the Amazon’s audio cue for dodging an attack would play when non-Amazon characters used the Evade skill granted by the Hustle Rune Word. Amended various stability issues encountered during Online play. Ladder Play
Fixed an issue where messaging for the next Ladder Season was inaccurate during the pause between seasons. Fixed an issue where characters that were recently converted from Ladder to Non-Ladder would not display as such and failed to join games. Fixed an issue where Rune Words exclusive to an upcoming Ladder Season could be created in the current season. Fixed an issue where converted Ladder characters would be incorrectly displayed with the Ladder flag. PC Specific
Fixed an issue where controller input would stop registering if the user swapped to Legacy graphics while the animation for selecting a character in the character creation screen was playing. Players will now be notified of when they’re running the game with old, extracted data. Console Specific
Fixed an issue where a player’s displayed location on the Friends List wouldn’t properly update on Xbox consoles. Fixed an issue where players on Nintendo Switch would not appear in the Recently Played With tab. Fixed an issue where the localized text for Personalized Items on console displayed all gendered pronouns at once in Polish and Spanish. Modding
Increased the total limit of state entries from 255 to 511. Added DataVersionBuild.txt. It is recommended that mod authors include this file in their mods to reduce unexpected errors between game versions. New columns have been added. Developers of existing Offline Single Player mods can remake their changes with new data or they can add new columns manually before merging. TreasureClassEx.txt, cubemain.txt, UniqueItems.txt "ladder" -> "firstLadderSeason", "lastLadderSeason" Runes.txt "server" -> "firstLadderSeason", "lastLadderSeason" Back to Top
