Dates and game state
| Field | Archive record |
|---|---|
| Start: source calendar date | 21 September 2018 |
| End: source calendar date | 06 January 2019 |
| Live patch | 2.6.1 |
| Season theme | Boon of the Horadrim |
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
Each completed set of five act bounties awards two Horadric Caches. The second cache also scales with difficulty; Challenge Rift rewards are not doubled. This accelerates materials and plans rather than attacks themselves.
Patch changes and historical boundaries
This season uses the named theme on patch 2.6.1. Profile assignments use only items available at that time; later seasonal powers remain separately labelled.

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 | Wrath of the Wastes |
| Crusader | Roland's Legacy |
| Demon Hunter | Unhallowed Essence |
| Monk | Raiment of a Thousand Storms |
| Witch Doctor | Helltooth Harness |
| Wizard | Tal Rasha's Elements |
| Necromancer | Bones of Rathma |
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 buildAkkhan: Condemn · before the Phalanx rework
Akkhan and Prophet form the base. Blade of Prophecy/Frydehr scale manually cast Condemn; Focus/Restraint additionally need Slash hits.
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 buildSunwuko: Wave of Light · 2.6.1
Vengeful Wind supplies Sweeping Wind stacks for Sunwuko. Tzo moves the bell to its target; Kyoshiro and Incense Torch strengthen it while Air Ally covers Spirit spikes.
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 buildArachyr: Firebats · classic melee version
Cloud of Bats rewards sustained channeling near the pack. Arachyr, Bakuli and Chiroptera form the engine; Haunt and Locust satisfy the old Ring of Emptiness requirements.
View buildTal Rasha: fast Meteor channeling · 2.6.1
Tal Rasha uses four damage elements. Aether Walker speeds travel while old Etched Sigil casts Meteor through channeling; Deathwish and Nilfur scale the damage engine.
