Changes Tested in PTR Patch 1.4.0

The primary focus of the Season 4 PTR was the itemization overhaul and new crafting system. Servers were active across North America, Europe, Korea and Japan, South America, and Australia. Players logged into the PTR via Battle.net and carried over their account's campaign completion status, mounts, skill points, Fog of War state, Altar of Lilith bonuses, and similar account-wide data.

Features Available for Testing

• Instant Level 100 character boost via an NPC named "PTR Boost" in Kyovashad.
• Boost rewards included 100 million gold, 1,000 Obols, two random sets of Ancestral gear at item power 920, upgraded potions, fully unlocked Paragon Glyphs, and up to 10 class-specific Tempering Manuals.
• Basic consumable materials were provided; Masterworking materials, Scattered Prisms, and Resplendent Sparks were excluded.
• The boost could be repeated with new characters and items were tradeable between PTR characters.
• Fog of War was fully cleared for all testers, and legendary drop rates were doubled regardless of boost usage.
• The Codex of Power was not fully unlocked during the PTR to preserve specific testing flows.

Class systems were complete during the PTR—enchantrments for the Sorceress, Companions for the Druid, and so on—allowing realistic high-level build testing.

Providing Feedback During the PTR

Player feedback during the PTR directly shaped the Season 4 launch. Two channels were available:

In-Game Feedback Tool

While playing the PTR, pressing Esc opened the in-game menu. Selecting "Report a Bug," then choosing "In-game feedback tool" from the dropdown filter let players submit observations without leaving the game.

Diablo IV PTR Forums

Blizzard also set up dedicated PTR forum threads where players posted feedback and engaged directly with developers and the community. Both channels remained active for the duration of the April 2–9 testing window.
