Diablo 4 Tempering Guide – How to farm Aspects in Diablo IV

Ok, Sanctuary Traveler. We already created a guide about the Masterworking gear upgrade system in Diablo 4 Season 4: Loot Reborn, but we completely forgot to tell you about something much more important — the Diablo 4 Tempering guide. While Masterworking focuses on things like what to craft, how many aspects to farm, and the percentage increase in farmed gear, the Diablo 4 Tempering guide is about what to farm and how to farm it! So, strap in, prepare for the hot road, and let the mobs’ projectiles cast twice. You’ll learn:

1. How to add up to two affixes or stats to your weapon/armor.
2. Where to achieve all those tempers.
3. The difference between Magic, Rare, and Legendary Tempers.

And many other helpful things. If you think we missed something, you’re welcome to check out our Masterworking guide, where we spent all our time explaining how many materials and aspects you need to get the best hellish gear ever!

How Tempering are limited by slots?

It’s got its own set of rules, especially when it comes to what goes where. Normal and Sacred items get to play with one tempering affix each, while the Ancestral items are big enough to handle two—but they have to be from different categories. And don’t get your hopes up about Unique items; they’re left out of the tempering fun. Each type of gear has specific slots that these tempering affixes can fill, and here’s how they break down:

Equipment Type	Compatible Tempering Slots
Helms	Defensive, Utility
Chest Armor	Defensive, Utility
Gloves	Offensive, Utility
Pants	Defensive, Utility
Boots	Mobility, Utility
Amulets	Defensive, Utility, Offensive, Mobility, Resource
Rings	Offensive, Resource
Weapons	Offensive

Each slot can only rock one tempering affix for Normal and Sacred gear, while Ancestral gear gets to mix and match two—as long as they’re not from the same category.

Tempering Cost + approximated costs

When it comes to decking out your gear in Diablo 4, tempering isn’t just a click and go; it costs you materials based on how badass your equipment is. The mightier the item, the heftier the material toll. Think of it as paying your dues for that next level power-up—no free rides in Sanctuary!

Here’s a breakdown of what you might spend based on item level, so you can plan your loot spree accordingly:

ILVL Range	Cost in Materials
1-300	5x Iron Chunk, 10x Veiled Crystals
301-600	8x Iron Chunk, 15x Veiled Crystals, 1x Baleful Fragment
601-900	10x Iron Chunk, 20x Veiled Crystals, 2x Baleful Fragment
901+	15x Iron Chunk, 30x Veiled Crystals, 3x Baleful Fragment

These costs ramp up as your gear’s item power does, ensuring you’ve got to put in work to get those killer affixes like lightning damage lucky hits or cool new moves with wind shear projectiles. Whether it’s adding a punch to your dual wielded weapons or upping the speed with movement for 4, you’ll need the right materials in your stash.

Tempering reroll

In the Diablo 4 tempering game, rerolling is your wildcard. It’s your chance to spin the wheel on those tempering affixes again if the first roll didn’t quite hit the mark. But, hold your horses—each piece of gear can only endure up to 5 rerolls. Beyond that, you’re locked in, for better or worse, so it pays to roll wisely.

Here’s the catch: you can’t keep the old roll if the new one stinks; you get what you roll, no take-backs. This makes rerolling a high-stakes game, especially if you’re gunning for the best perks like lightning damage lucky hits or faster barrage projectiles. And if you’re all about optimizing, like squeezing the best out of your two handed slashing weapons or maximizing ancient’s cooldown reduction, you’ll want to consider the odds carefully. Each reroll shuffles the deck from the same temper manual, so if your manual is stacked with options (say, 4 or more affixes), your chances of hitting that jackpot drop with each spin.

Conclusion

From enhancing the deadliness of your barrage with heartseeker projectiles to increasing the durability of your helms and chest armor, Tempering offers an unrivaled opportunity to mold your character’s abilities and strengths.

Whether you’re strategically placing boulder projectiles to maximize area control, or timing your dark shroud projectiles for optimal stealth attacks, the variety of Tempering Manuals available ensures that every class can benefit from these powerful upgrades. With the ability to apply such modifications as blight projectiles for poison damage or flurry projectiles for rapid attacks, the flexibility is nearly endless.

Remember, the costs associated with this customization scale with your item’s power level, making it essential to gather the necessary materials like Iron Chunk, Veiled Crystals, and occasionally, Baleful Fragments as you level up. And while the prospect of rerolling a Tempering Affix can feel like a gamble—especially with high-stakes outcomes that could dramatically alter your playstyle—the ability to potentially double down on a powerful affix like a lightning bolt damage lucky hit or an ancients cooldown reduction makes it a risk worth considering.

Ultimately, the key to mastering the Tempering system lies in understanding and navigating its complexities—from choosing the right Tempering Manuals that align with your desired combat tactics to knowing when to take the plunge on a reroll. By leveraging this robust system, you’re not just preparing for battle; you’re engineering your path to becoming a legend in Sanctuary.
