Diablo 4 S15 Season of Hell's Legacy Gear Runes and Materials Guide

Diablo 4 Season of Hell's Legacy changes how players approach early-season progression with new Legacy Uniques, Soul Spike Shards, updated crafting options, and additional ways to work toward powerful endgame gear.

You don't need to chase every new item immediately. During the early season, the most useful resources are the ones that help establish your build, improve damage and survivability, and prepare you for endgame farming. As your character progresses into Torment, the priorities shift toward Ancestral gear, Greater Affixes, Mythic Uniques, Boss materials, and advanced crafting.

Here are the gear and resources worth paying attention to throughout your Season of Hell's Legacy progression.

Legacy Uniques Add New Build Options

Season of Hell's Legacy introduces nine Legacy Uniques, bringing classic Diablo items into Diablo 4. They are permanent additions and are available in both Seasonal and Eternal Realms.

The Legacy Unique lineup includes:

• Leoric's Crown
• Nemesis Bracers
• Stone of Jordan
• Squirt's Blouse
• Arioc's Needle
• Henri's Perquisition
• In-Geom
• The Furnace
• Messerschmidt's Reaver

Their value depends on the class and build rather than simply being new items. Some can provide useful effects during progression, while others may become more relevant to specific endgame setups.

For early-season characters, the important point is to check whether a Legacy Unique actually supports your build before replacing a well-rolled Legendary or Ancestral item.

Soul Spike Shards Give Seasonal Builds More Flexibility

Soul Spike Shards are part of the new Season of Hell's Legacy progression system and give players another way to customize their characters.

They come in different rarities, with higher-rarity versions offering stronger potential effects. However, rarity alone does not determine whether a Soul Spike Shard is useful for your character.

When evaluating them, consider:

• Whether the effect works with your main build
• How it interacts with your damage or defensive setup
• Whether it provides a meaningful benefit at your current progression stage
• Whether upgrading it is worth the required resources

Instead of immediately chasing the highest rarity, focus on effects that provide a real improvement to your current build.

Runes Still Matter for Season of Hell's Legacy Progression

Runes remain an important resource for Diablo 4 character progression. Their value comes from how they interact with the game's Runeword system and the build options available to your character.

During the early season, it is worth keeping useful Runes instead of treating every drop as disposable. As your core equipment becomes established, Runes can become more valuable for further crafting and build optimization.

When deciding which Runes to keep, consider:

• Whether they are useful for your planned Runewords
• Whether they fit your current build
• Whether you need multiple copies for future crafting
• Whether they are required for other Rune-related recipes

This is especially useful when transitioning from leveling gear into a more complete endgame setup, when your resource requirements begin to increase.

Lair Boss Materials Become More Valuable in Endgame

Once your character reaches endgame, Lair Boss materials become increasingly important for targeted farming.

Boss encounters provide opportunities to obtain Unique items and other valuable rewards, while Season of Hell's Legacy also offers additional ways to work toward Mythic Uniques.

You do not necessarily need to spend every Boss material as soon as you obtain it.

For a fresh character, it can be more efficient to strengthen your build first and then use accumulated materials when you can clear the relevant encounters consistently.

This makes Lair Boss Keys and Stygian Stones worth paying attention to as you move deeper into Season of Hell's Legacy endgame progression.

Affix Value Reroll Makes Strong Gear Worth Keeping

One of the useful Season of Hell's Legacy crafting additions is Affix Value Reroll, which gives players another way to improve promising equipment.

Instead of completely replacing an item because an affix has a poor numerical value, you can use the recipe to reroll eligible affix values while protecting certain valuable properties.

The system can preserve properties such as:

• Greater Affixes
• Enchanted affixes
• Tempers
• Applicable Transfigurations

This makes high-quality equipment more worth keeping.

For example, if an item already has the Greater Affix and Temper combination you need but one numerical affix value is underwhelming, rerolling its value may be more practical than starting the search for another item from scratch.

Ancestral Bases Deserve More Attention in Torment

Once you reach higher difficulty levels, Ancestral Gear becomes an important part of long-term progression.

Season of Hell's Legacy gives Common, Magic, and Rare items the potential to appear as Ancestral items with Greater Affixes. These items can therefore serve as valuable crafting bases rather than being automatically treated as junk because of their rarity.

When checking potential bases, pay attention to:

• Ancestral quality
• Greater Affixes
• Useful base stats
• Whether the item supports your intended build
• Its potential as a crafting base

This creates another reason to inspect certain low-rarity drops instead of automatically salvaging or selling everything that isn't Legendary or Unique.

Mythic Uniques Are a Long-Term Endgame Goal

Mythic Uniques remain some of the most powerful pieces of gear for endgame builds, but they are generally a later progression goal rather than something you need to complete immediately after starting a seasonal character.

Season of Hell's Legacy expands the ways players can work toward Mythic Uniques through different endgame systems and crafting options.

Because of this, early-season players should first focus on building a reliable character capable of farming endgame content. Once your core gear is established, Boss materials, Runes, crafting resources, and other progression materials become increasingly important for pursuing Mythic upgrades.

You don't need to sacrifice your entire early-season progression just to chase a single Mythic Unique target.

What Should You Prioritize During Season of Hell's Legacy?

Your priorities naturally change as your character progresses.

During Leveling

Focus on:

• Core Legendary and Unique effects
• Gear with useful stats for your build
• Soul Spike Shards that complement your setup
• Useful Runes
• Basic crafting materials

At this stage, there is little reason to spend large amounts of resources perfecting equipment that you will replace soon.

When Entering Endgame

Start prioritizing:

• Ancestral gear
• Greater Affixes
• Build-specific Unique items
• Useful Soul Spike Shards
• Runes for your planned setup
• Lair Boss materials
• Crafting resources

Your goal is to create a stable build that can farm endgame activities efficiently.

When Optimizing Your Build

Once your main equipment is established, shift your attention toward:

• Better affix values
• Greater Affixes
• Strong Ancestral bases
• Build-specific Uniques
• Mythic Uniques
• Runewords
• Affix Value Rerolls
• Boss farming materials

At this stage, targeted upgrades are generally more useful than simply collecting more gear.

Need to Complete Your Season 15 Setup Faster?

If you're missing specific gear, Runes, Gold, or Lair Boss materials for your build, MMOSO offers Diablo 4 Season 15 items and resources to help you move from leveling into endgame progression more efficiently.

You can explore options across Diablo 4 Items, Runewords, Gold, and Lair Boss Keys & Stygian Stones based on what your current build needs.

Conclusion

Diablo 4 Season of Hell's Legacy brings more ways to build and refine your character, but resources vary in value at different stages.
While leveling, focus on your core build, key gear, Soul Spike Shards and Runes. Once you hit endgame, ancestral gear, Greater Affixes, boss materials and crafting supplies become vital for working toward Mythic Uniques.
Prioritize farming and crafting based on your current progress instead of chasing perfect gear all at once.
