New Season Theme

Season 18 introduced the Season of the Triune, a call-back to an ancient cult forged over three millennia ago by the Prime Evils of the Burning Hells. Masquerading as three benevolent deities dedicated to Determination, Creation, and Love, the Prime Evils sought to infiltrate the hearts of men in a bid to tilt the odds in their favor in the ongoing Eternal Conflict. Ultimately defeated by Uldyssian during the Sin War, the remnants of the Cult of the Triune still operate today as the more well-known Coven, whom continue the work of Adria and Magdha even after their deaths.

For the duration of Season 18, all players will benefit from the Power of the Triune buff, which will periodically summon circles around the battlefield that provide one of three random buffs:

• Triune of Love (Power): Players in the circle receive a 100% damage bonus while active
• Triune of Determination (Resource Reduction): Players in the circle receive a 50% discount on resources spent while active
• Triune of Creation (Cooldown Reduction): While standing in an active circle, any skills currently on cooldown come off of cooldown more quickly

We wanted to try something different this Season, and especially wanted to provide a change to your gameplay from the very first moment you begin your journey. This buff alters gameplay from level 1 to level 70 and beyond, providing an enticing reason to move around the battlefield to leverage these powerful boosts. We’re looking forward to seeing how players utilize these ancient powers from their first level to their final Greater Rift push!

Season 18 Cosmetic Rewards

Beginning with Season 17, we began re-introducing previous Seasonal rewards to make them available to players who may have missed them the first time around. For Season 18, this means awards that were originally available from Season 6 are returning to the Season Journey.

In addition to the Chest and Gloves slots of the exclusive Conqueror Set, players will be able to earn a series of portrait frames bedecked with the mysterious beauty of Blood Shards. A ghastly All Hallow’s pennant will also be available, allowing you to proudly proclaim your love for all things grim and creepy.

Season Journey Rewards

If you’ve been diligently slaying demons for the past few Seasons and reached Conqueror in the Season Journey each time, you’ve surely acc rued a few extra stash tabs. You’ll earn one additional tab each Season by finising the Conqueror tier, up to a maximum of five:

• Guardian of Sanctuary: Finish a level 70 Nephalem Rift on Torment XIII within five minutes
• Gem of My Life: Level three Legendary Gems to level 55
• All I Do IS Win: Complete two Conquests this Season
• Disarm You: Kill Rakanoth at level 70 in under 15 seconds on Torment XIII difficulty
• Money Ain’t A Thang: Slay Greed on Torment XIII difficulty
• Take U There: Reach Greater Rift level 60 Solo
• Power Amplification: Use Kanai’s Cube to augment an Ancient Legendary item with a level 50+ gem
• Cubic Reconfiguration: Use Kanai’s Cube to reforge a Legendary item

Seasonal Conquests

Want to prepare your Conquest plan for Season 18? Here are the challenges you’ll face!

Push your way to Greater Rift level 75 to complete Divinity/Lionhearted. On a Good Day/I Can’t Stop guides you to get your Legendary Gem grind on; level three Legendary Gems to 65 to complete this challenge! For the speedy, Speed Demon/Need for Speed requires the fastest nephalem to complete a Nephalem Rift at level 70 on Torment X or higher in under two minutes. 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. For the fiercest demon slayers, Boss Mode/World’s Apart is a speed challenge where you’ll need to eliminate the following bosses at level 70 and Torment X in under twenty minutes:

• The Skeleton King
• The Butcher
• Zoltun Kulle
• Ghom
• Cydaea
• Rakanoth
• Diablo
• Adria
• Queen Araneae
• Maghda
• Belial
• Siegebreaker Assault Beast
• Azmodan
• Izual
• Urzael
• Malthael

Haedrig’s Gift

Finally, the Class Sets rewarded for completing certain chapters in the Season Journey courtesy of Haedrig’s Gift have rotated once more. We’ve listed 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 will 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 18:

• Barbarian – The Legacy of Raekor
• Crusader – Armor of Akkhan
• Demon Hunter – Embodiment of the Marauder
• Monk – Inna’s Reach
• Necromancer – Pestilence Master’s Shroud
• Witch Doctor – Zunimassa’s Haunt
• Wizard – Delsere’s Magnum Opus

Seasons

• The buff for Season 18, the Season of the Triune, has been added
  • Triune's Will: All abilities have a chance when hitting an enemy to spawn a circle that gives a power. Only one circle can be active at a time.
    • Triune of Love (Power): Players in the circle receive a 100% damage bonus while active
    • Triune of Determination (Resource Reduction): Players in the circle receive a 50% discount on resources spent while active
    • Triune of Creation (Cooldown Reduction): While standing in an active circle, any skills currently on cooldown come off of cooldown more quickly
  • Developer Comment: The last couple of Seasonal buffs have been focused primarily on end-game content. We wanted to try something different this Season with a buff that was more beneficial to players regardless of where they might be in their Season Journey. Triune's Will can come into play as early as level 1 and continue to make an impact on your game experience from the beginning to the end of the Season, and we're looking forward to seeing how players leverage this ever-changing boost throughout their adventures!
  • Developer Comment: In addition, we received feedback from players during the PTR about colorblind accessibility. We've changed one of the blue-tinted circles to a darker, green earth tone that should stand out a lot more for affected players. We greatly appreciate your feedback!

Items

• Developer Note: There are additional specific notes below, but broadly for 2.6.6, we wanted to introduce a handful of new item powers targeted at two audiences: (1) certain classes with long-standing requests for balance/quality of life adjustments and (2) the broader player base for experimenting with Kanai's Cube. This means fewer class-specific new additions, but more additions that everyone has an opportunity to play with. We also experimented with making some of the craftable sets from Haedrig more appealing for fresh level 70's or players looking to maximize their farming runs. We hope to see some interesting new theorycrafting and tactics out of 2.6.6 and can't wait to see what the community does with this new loot!
• Updated Item Notes: There are a number of notes below clarifying the intention of certain item functionalities. In a couple cases, such as with Flavor of Time, the item wasn't behaving properly during PTR per our intentions (which has been fixed). For others, we just wanted to provide more clarity about exactly how these items behave.
• Flavor of Time
  • New Legendary Power: Pylon effects last twice as long.
  • Note: Only wearers of this item gain this effect. This is intended.
• The Executioner
  • New Legendary Power: Attacks will slay enemies with less than (5-10%) health.
  • Note: This item's power does not work on followers. This is intended.
• Stone Gauntlets
  • New Legendary Power: Getting attacked will slowly turn you to stone... (You gain 50% more armor, but your movement speed is reduced by 15% and attack speed is reduced by 20%. This effect stacks up to 5 times)
  • PTR Update: This item now displays a buff icon and has a clearer in-game description. Thank you for the feedback!
  • Note: Immunity to control-impairing effects can work against the reduced attack and movement speed penalties. This is intended.
• Echoing Fury
  • New Legendary Power: Slaying enemies engulfs the wielder into a Frenzy. (Killing enemies increases your attack speed by 15% and movement speed by 5%. This effect stacks up to 5 times)
  • PTR Update: This item's power now works on kill assists and pet kills. Thank you for the feedback!
• Squirt's Necklace
  • New Legendary Power: While not taking damage, your damage is increased by up to 100% and damage taken is increased by up to 50%.
  • PTR Update: This item now displays a buff icon. Thank you for the feedback!
• Messerschmidt's Reaver
  • New Legendary Power: Reduce the remaining cooldown of one of your skills by 1 second when you slay an enemy.
  • PTR Update: This item's power now works on kill assists and pet kills. Thank you for the feedback!
• Mortick's Brace
  • New Legendary Item: Wrath of the Berserker gains the effect of every rune.
  • Developer's Note: If you played during the Patch 2.2.0 PTR, you'll recognize this as an item that was later removed from the game before it went to live servers. At the time, Mortick's Brace gave too much power for a single item slot. However, the power curve of Diablo III has changed significantly since then and we're comfortable with bringing it back.
  • Developer's Note: We're not done with Barbarians, either. However, this is a change that required less testing and could be easily added to 2.6.6, so rather than waiting for a larger batch of changes, we saw no reason to hold this one back.
• Spite
  • Note: This item can be crafted from the Blacksmith and is not a normal loot drop
  • New Legendary Power: Non-cleaving Gargantuans gain the cleave and chilling effects of the Humongoid rune.
• Legacy of Dreams
  • New Legendary Gem:
    • While you have no set bonuses equipped, every Legendary item you have equipped increases your damage dealt by 3.75% and reduces your damage taken by 2%. (Max level 99)
    • Rank 25: This bonus is doubled for Ancient items.
  • Developer's Note: The end game opened up significantly with Season 17's Legacy of Nightmare's buff (and the community was clear about how much these new options were appreciated), but wanted to make this addition a more permanent fixture in a more streamlined way than simply making it baseline. This Legendary Gem should open that path up even further and at more opportunities than just late game Greater Rift pushing.
• Crafted Sets
  • Note: The following sets have been significantly revised from their existing level 70 counterparts. Items crafted prior to 2.6.6 will continue to exist in their old forms but will not be updated after the patch. In addition, after the patch, the old recipes will no longer be available to craft and all players will need to re-acquire these recipes by finding the plans again through Horadric Caches or by killing Odious Collectors.
  • Sage's Journey
    • A Belt has been added to this set.
    • Haedrig the Blacksmith now automatically learns how to forge this set at Rank 12.
  • Captain Crimson's Trimmings
    • (2) Set Bonus
