Latest Changes That Affect Guides

5
PATCH 3.1.1UPDATE REQUIREDSeason

Season 14 Mythic Conversion Is Shorter

CHANGE

Upgrade to Mythic now costs four Pandemonium Fragments instead of five. High-Torment Deathtoll Chambers guarantee at least one Superior Lair Key, the Corrupted Reaper can drop up to two Fragments by Torment tier, and the repeatable Reputation reward guarantees one Fragment.

IMPACT

Retire five-Fragment farming tables and compare Deathtoll, Corrupted Reaper, and repeatable Reputation within one route.

ACTION

Use the current four-Fragment value in the Season 14 guide, while separating the conversion recipe as a Lord of Hatred route that requires the Horadric Cube unlock.

PATCH 3.1.1RECHECKSeason

Reputation, Tower, and Rupture Progression Fixes

CHANGE

Adds the Seasonal Reputation Board to Temis and fixes a Season Rank objective, party Tower rewards, the Corrupted Reaper lair, and Rupture spawning.

IMPACT

Do not preserve workarounds for fixed blockers; treat them as known issues only if they still reproduce.

ACTION

Re-test old workaround articles before publication.

PATCH 3.1.1RECHECKFarming

Mythic Drops Fixed for Lair Bosses and Other Sources

CHANGE

Fixes sources—including Lair Bosses—that could not drop Mythics and increases the chance that a naturally dropped Mythic is an Iconic Mythic.

IMPACT

Remove pre-fix claims that lair bosses cannot drop Mythics. Blizzard gives no exact rate, so do not publish an inferred drop percentage.

ACTION

Update boss and farming eligibility while marking the rate as undisclosed.

PATCH 3.1.1RECHECKClass

Re-check Class Behavior That Depended on Bugs

CHANGE

Fixes Paladin Holy-damage display, Spiritborn Stinger overperformance, Warlock Soul Shard clarity and set behavior, plus targeted Barbarian, Druid, and Rogue bugs.

IMPACT

DPS comparisons or instructions built around pre-fix behavior require retesting. A bug fix alone does not justify changing a whole-class ranking.

ACTION

Flag only builds using the affected skill or set as refresh candidates.

PATCH 3.1.1REVIEWActivity

War Plans Boss and Whisper Reward Fixes

CHANGE

Fixes mutators that could prevent boss or Whisper Ambush loot and a case where the Corrupted Reaper failed to gain power.

IMPACT

Do not document missing loot as intended behavior; log it only if it reproduces after 3.1.1.

ACTION

Base War Plans known-issue notes on 3.1.1.

Current Baseline Changes

PATCH 3.1.0UPDATE REQUIREDSystem

Unique Item Evaluation and Crafting Changed

CHANGE

All Uniques now guarantee two affixes on drop. Unique, Mythic Unique, and Iconic Mythic items can have affixes altered through Enchanting, and Upgrade to Mythic preserves the gear slot. Mythic Uniques themselves cannot be used in that recipe.

IMPACT

Pre-3.1 fixed-affix tables and same-recipe slot uncertainty are obsolete. Item guides must separate guaranteed affixes from editable ones.

ACTION

Rebuild item and crafting guides from live 3.1.0+ items and official tables.

PATCH 3.1.0UPDATE REQUIREDBuild

Revalidate Build Numbers for All Eight Classes

CHANGE

Large skill, Aspect, Unique, Paragon, and Talisman adjustments affect all eight classes. Buffs and nerfs are mixed and cannot be reduced to one class ranking.

IMPACT

Pre-3.1 skill values, item choices, Paragon instructions, and strongest-build claims are not valid evidence for current builds.

ACTION

Before publishing a build, check that class's 3.1.0 section plus 3.1.1 fixes.

Farming Rewards, War Plans, and Currency Caps Updated

CHANGE

Updates Rupture rewards and low-difficulty tuning, shared War Plans, Helltide chests, and Infernal Hordes gold. Caps rise to 25,000 Obols, 999,999,999,999 Gold, and 999,999,999 Gem Fragments.

IMPACT

Revisit spending routines built around old caps and farming priorities based solely on old rewards.

ACTION

State the tested difficulty and 3.1.0+ patch scope in farming guides.

PATCH 3.1.0REVIEWGlossary

Use the Current Tier-3 Boss Key Name

CHANGE

Betrayer's Husks were renamed Superior Lair Keys because Belial is no longer the only boss in that tier.

IMPACT

Use Superior Lair Key as the canonical live label and retain Betrayer's Husk only for legacy search and historical context.

ACTION

Replace the display name during migration while preserving the search alias.
