Diablo 4 Season 15 Is Coming - Here's What You Should Be Doing Right Now

Diablo 4 Season 15 will launch on September 15, 2026, bringing new gear, new game mechanics, and endgame content. So, before the season begins, you need to do some preparation. Insufficient preparation could put you at a disadvantage from the start.

This article will guide you through four things to do before Diablo 4 Season 15 begins, helping you have a better gaming experience.

Diablo 4 Season 15 Is Coming - Here's What You Should Be Doing Right Now

Stop All Mythic Upgrades Right Now

This is the most important thing you can do before the season ends. Do not use current Mythic gear upgrade recipes. In the current system, when you use Pandemonium Fragments to upgrade a Unique to Mythic quality item, you will receive a random Mythic item in the same slot.

This means you might sacrifice items with perfect stats, ideal affixes, and maxed-out crafting levels, only to end up with an item that is completely unsuitable for your build. This cruel gamble can be frustrating for players throughout the entire season.

Season 15 will completely change this mechanism. The developers have removed the random reforging of Mythic gear, replacing it with recipes that directly upgrade to Mythic. More importantly, this upgrade will retain your original gear's affixes, enhancement options, and all refinement progress.

This means that if you have a Unique piece of gear with perfectly distributed stats, you can upgrade it to Mythic without losing any carefully tuned attributes such as your critical strike chance, cooldown reduction, or vulnerability damage. Your item will also gain Mythic-level power and an additional affix slot.

Hoard Reputation Bags and Materials

After Diablo 4 Season 15 launches, Superior Lair Keys will be added to Glints of Hope Reputation caches. While the rewards from these chests are currently decent, the addition of Keys will significantly increase their value.

Therefore, my advice is: stop opening your Glints of Hope Reputation caches now. All chests stored in your inventory or stash should be left unopened until Season 15 launches.

Each chest will have a chance to drop valuable Superior Lair Keys. Players opening chests now are essentially wasting keys that could potentially save you dozens of hours of grinding time in the future.

Besides Glints of Hope Reputation caches, you should also stockpile all crafting materials, such as Veiled Crystals, Abstruse Sigils, and Forgotten Souls. Then, avoid crafting unnecessary items and don't upgrade equipment you're not entirely confident in. Every material you save now will be a huge asset in Season 15.

If you want to acquire more materials, join IGGM Diablo 4 Facebook Group. We're having a giveaway event, and if you're lucky, you'll receive a large amount of resources, including 50,000 × Superior Lair Key, 500 × Crux of the False Prophet, 1,000 × Corrupted Roots, 40 × Gems & Horadric Gems (Selectable).

Stockpile Gold

In Season 15, Gold will be more important than ever. Mythic Gear crafting system requires not only Pandemonium Fragments and Resplendent Sparks, but also a significant amount of gold.

Every reforging, every master enhancement, and every enchantment requires gold, and the higher the gear level, the higher the cost per attempt. This could potentially allow you to spend millions of gold in the first week of the new season.

Therefore, players can start farming gold now. Helltides with suitable affixes, high-level Nightmare Dungeons, and Lair system itself are excellent ways to obtain gold and valuable Diablo 4 items, which can be sold to merchants or traded.

The more gold you accumulate now, the faster you can craft your first Mythic craft in Diablo 4 Season 15.

Understand Soul Splinter System

Season 15 introduces Soul Splinter System, and to ensure you use it effectively, you need to understand it before the game officially launches.

Soul Splinters are a new type of socketable item that can be socketed into rings and amulets. They are not ordinary gems and do not directly provide attribute bonuses. However, they are a key source of power that determines your character's build. Here's how it works:

While each Soul Splinter provides significant positive effects, such as greatly increasing critical strike chance, core skill damage, or significantly reducing ultimate skill cooldown, each splinter also inflicts a negative effect. For example, you might gain +30% critical strike chance, but your primary resource cost increases by 25%.

Or, you might gain +40% damage to vulnerable enemies, but lose 20% movement speed. Trade-offs are real and designed to force you to make meaningful choices about your build.

Soul Splinters are powerful, and you'll want to use them, but their drawbacks mean you can't simply equip the strongest splinters and call it a day. You need to understand what disadvantages your build can tolerate.

Therefore, before Diablo 4 Season 15 begins, you can start thinking about which build you should choose. Planning your build around these trade-offs will give you an edge over players who blindly equip splinters.


If you find yourself missing certain items while building your build, don't worry! Once the new season launches, you can directly buy Diablo 4 Items from IGGM.com, and we'll provide you with the resources you need as quickly as possible.

Furthermore, if you register, log in, and check in daily from now on, you can accumulate a lot of points through IGGM Points System; then use these points to offset costs when placing orders and save money!

That concludes this article about the four things you need to do before Season 15 begins. If you don't complete these tasks, you'll struggle to catch up in the new season, while other players will already be dominating Torment 4 difficulty. So, start preparing now and follow the steps above to get ahead of the competition.
