Platforms and timing boundaries
PC and supported console editions have separate platform leaderboards. Diablo III does not support cross-platform multiplayer. Do not assume PC fixes and console schedules were identical.
Nintendo Switch released during Season 15 in November 2018; later seasons also run there. PS5/Series consoles use the compatible PS4/Xbox One editions.
Calendar dates are archive records, not live spawn calculations. Regional PC launches and the global console start can fall on different German calendar dates; the linked Blizzard announcement supplies the relevant rule.
What this season changes in play
Hits can create one of three Triune circles: damage, lower resource costs or faster recovery of active cooldowns. Positioning and burst order follow the actual circle; a desired circle is not permanently available.
Legacy of Dreams is introduced. It frees rings from the LoN pair but requires a levelled gem and still no active set bonus. Newly crafted Crimson/Aughild pieces must use the new recipe version.
Patch changes and historical boundaries
2.6.6 introduces LoD, new legendary powers and new crafted set versions. Mortick’s Brace becomes genuinely live here; earlier PTR mentions do not prove a Season 3 drop.

Convert the starter set into the target build
The table shows the starter set, not automatically the linked endgame build. Open gifts on the intended class and follow period Journey objectives; early S5/S6 progression differs from the later Chapter II/III/IV scheme.
Activate the set bonus actually within reach first and collect its core weapon through Kadala, rare upgrades and Kanai’s Cube where those systems already exist. Do not replace useful pieces before completing the target bonus.
This season’s Haedrig sets
| Class | Starter set |
|---|---|
| Barbarian | The Legacy of Raekor |
| Crusader | Armor of Akkhan |
| Demon Hunter | Embodiment of the Marauder |
| Monk | Inna's Mantra |
| Witch Doctor | Zunimassa's Haunt |
| Wizard | Delsere's Magnum Opus |
| Necromancer | Pestilence Master's Shroud |
Optimise step by step
Step 1
Complete the linked profile engine: check six skills, four passives, equipped slots and available Cube powers.
Step 2
Test resources, protection and buff uptime a few rift tiers below the current limit. Only then reroll toward more offensive stats and test longer boss windows.
Step 3
Separate farming and pushing: fast elite chains use different gems and cooldown assumptions from long Rift Guardian fights. A source’s rift tier is no performance promise at other Paragon or on another platform.
Evidence and verification boundary
Linked profiles distinguish contemporary author bars, documented patch rules and explicitly added editorial slot repairs. No historical rank-one rating is asserted without an archived benchmark. German and English contain the same information.
Class builds for this season
Choose your class. Profiles state their historical version and full-setup requirements.
Immortal King: HotA · 2.6.1–2.6.6
Immortal King keeps Ancients permanent; Fury spending reduces Berserker cooldown. Istvan weapons, Gavel and First Men concentrate damage into rapid Fire hammers.
View buildInvoker: Thorns with Pig Sticker
Invoker transfers Thorns into fast Punish hits. Pig Sticker supplies attack speed and stats; Akarat’s Awakening reduces cooldowns through blocks while Trove maintains the Bombardment condition.
View buildShadow: Impale · classic Ricochet version
Shadow, Karlei and Holy Point Shot form an elite-focused build. Karlei refunds require targets already hit by Impale; enemies that die too quickly create sustain gaps.
View buildLoD: Wave of Light · first LoD season
The new LoD gem replaces the LoN ring pair. Epiphany/Rabid Strike copy bells while Bindings of the Lesser Gods and Pinto connect control with the Fire attack.
View buildLoD Singularity Mages · group-farming archive
LoD, Singularity and Cycle convert full Essence into companion damage. Period Haunted Visions extends temporary Simulacrums; this is not yet the permanent Masquerade version.
View buildPestilence: Corpse Lance · 2.6.1
Pestilence supplements manual Lances through corpse consumption. Brittle Touch builds critical chance; Reservoir and Shadowhook tie the burst to Essence.
View buildLoD Carnevil: Poison Darts · Season 18
Carnevil directs Fetishes at Dart targets and Dagger of Darts makes their shots pierce. LoD and Jeram replace a class set; Echoing Fury rewards sustained kills.
View buildVyr/Chantodo: Squirt and Triune · Season 18
The Vyr loop combines Chantodo, Swami and Fazula with Squirt’s newly enhanced 2.6.6 effect. Shields maintain the risky amulet.
