A step-by-step Horadric Cube, Tempering and Masterworking guide for turning a Greater Affix Movement Speed base into endgame boots.
The finished example reaches 86% Movement Speed on one pair of boots: 36% from the base Greater Affix and 50% from the tempered Movement Speed line.
Season 15 has quietly changed what counts as a “good drop.” A blue Ancestral item with one exceptional Greater Affix can now be a better crafting project than a yellow or orange item that looks finished when it hits the ground. The Horadric Cube lets us remove, add and reshape affixes, the Occultist gives us one controlled enchant, Tempering adds a second Movement Speed line, and Masterworking pushes the finished item into frankly silly territory.
The example used in this guide finishes at 86% Movement Speed from the boots alone. That is not a guaranteed number on every attempt, because the temper roll and final Masterwork result still matter, but the method is repeatable. More importantly, it teaches the Season 15 crafting order that keeps your valuable Greater Affix protected while you build the rest of the item around it.
This is exactly why the Horadric Cube has become one of Season 15’s defining systems. We have already seen it used for hidden Diablo II-style Runewords, direct Mythic upgrades and new reroll recipes. For these boots, we are using the Cube as a precision workshop rather than a demon-themed slot machine.
The Target: What the Finished Boots Look Like
Important: Diablo IV’s character sheet shows a 200% Movement Speed cap from ordinary bonuses. A pair of boots this fast is most valuable when it lets you remove Movement Speed from other slots or hit the cap without relying on temporary effects.
Check the character sheet before over-investing. The normal Movement Speed display caps at 200%, so extra speed may be wasted if the rest of your build already reaches the ceiling.
What You Need Before You Start
A 900 Item Power Ancestral Magic pair of boots with a Greater Affix on Movement Speed. The cleaner the base, the better.
Enough Primordial Dust and Tuning Prisms to use Remove Affix, Add Affix and Focused Reroll several times.
A healthy Gold reserve. The Occultist and repeated endgame crafting are very good at turning “rich” into “I should farm again.”
The Natural Motion Tempering Manual, which can add a permanent Movement Speed temper to boots.
Masterworking materials, including Obducite and the materials needed to reroll the final Capstone bonus if it lands on the wrong stat.
Patience. The method gives you control over the process, not immunity from bad rolls.
If Masterworking materials are your bottleneck, our earlier look at the Obducite drop problem and its patch fix is a useful reminder of why endgame crafting can suddenly consume an absurd amount of one material. Our broader endgame discussion also explains why so many gearing paths eventually send players back toward high-end farming content.
Step 1: Start With a Greater Affix Movement Speed Base
The entire craft depends on the starting item. Look for 900 Item Power Ancestral Magic boots with a Greater Affix Movement Speed roll. In the example, the blue boots begin with +30% Movement Speed and an unwanted Maximum Life line. The important part is the star beside Movement Speed: that is the stat we refuse to risk.
The ideal starting point: Ancestral Magic boots with a Greater Affix Movement Speed line. The second affix is disposable.
Why start with a Magic item? Because it gives the Cube room to build. Season 15’s crafting system rewards “unfinished” bases when the one irreplaceable stat is already present. Salvaging a blue item like this because it is blue is exactly the old habit the new Cube is designed to punish.
This is part of the wider Season 15 itemization shift we discussed in our PTR feedback roundup: modern Diablo IV increasingly asks you to judge an item by what can be repaired, not simply by how many good lines it rolled naturally.
Step 2: Remove the Affix You Do Not Want
Put the boots into the Horadric Cube and use Remove Affix. The goal is to strip away the disposable second stat while preserving the Greater Affix Movement Speed. If the item contains affixes from different categories, a Tuning Prism can help narrow which category the Cube targets. Do not rush this part: the cleaner the base becomes, the easier the rebuild is to control.
Use the Cube’s Remove Affix recipe to strip the unwanted line while protecting the Movement Speed Greater Affix.
The clean base after removal: one Greater Affix Movement Speed line and plenty of room to rebuild the item.
Step 3: Rebuild the Boots With Add Affix and Focused Reroll
Now we rebuild instead of praying for a perfect natural drop. Use Add Affix to create new lines, then use Focused Reroll when a new affix lands in the right general category but is not the stat you actually want. In the example, the final supporting package is Intelligence, Armor and Maximum Life. Intelligence is the Sorcerer example; your own class can substitute the main stat or another affix your build values more.
A practical target order is: main stat first, Armor second, then use the final flexible slot for a stat you can replace at the Occultist. Because Add Affix can produce the wrong skill or utility stat, expect to cycle a few times. That is normal. The point is that the Greater Affix Movement Speed remains untouched while the rest of the item changes around it.
The boots have been rebuilt into a Rare base with main stat, Armor and the protected Greater Affix Movement Speed.
Step 4: Use the Occultist to Lock In the Final Defensive Stat
Once the boots have three useful lines and one replaceable line, move to the Occultist. Enchant the weakest affix into the final stat you actually want. In the example, Dodge Chance is replaced by Maximum Life, giving the item four useful lines: Intelligence, Maximum Life, Armor and Greater Affix Movement Speed.
The Occultist converts the expendable fourth line into Maximum Life. Enchanted affixes are protected from the Cube’s Affix Value Reroll.
That protection matters. Season 15’s Affix Value Reroll does not touch Greater Affixes, Tempered affixes or Enchanted affixes. By enchanting Maximum Life before the value-reroll stage, that line becomes one of the fixed anchors of the craft.
We previously covered the same protection rules when Season 15 expanded Affix Value Reroll for equipment, Charms and Seals. The recipe changes the numbers on ordinary base affixes while leaving the expensive parts of the item alone.
Step 5: Reroll the Remaining Base Values
Now use Affix Value Reroll in the Horadric Cube. This recipe randomizes the values of ordinary base affixes, but protects your Greater Affix Movement Speed and the Enchanted Maximum Life line. That makes it ideal for fishing better values on stats such as Armor and your main stat without risking the lines you have already secured.
Affix Value Reroll is the safe value-polishing step: Greater, Enchanted and Tempered affixes are excluded from the reroll.
Do not chase perfection forever. The example spends multiple rerolls trying to improve the ordinary affix values. A near-max roll is excellent; burning an entire material stockpile to move a stat by a handful of points is how crafting guides become bankruptcy guides.
Step 6: Temper Natural Motion for a Second Movement Speed Line
Take the boots to the Blacksmith and select the Natural Motion Mobility temper. The normal Movement Speed range is 15–25%. What we really want is the Greater Affix version of the temper. In the example, the Greater Temper initially lands at +31% Movement Speed before Masterworking, already above the normal maximum range.
Natural Motion is the key Mobility temper. Select permanent Movement Speed rather than the temporary “after killing an Elite” option.
A successful Greater Affix Temper pushes Movement Speed above Natural Motion’s normal 25% maximum. Here it lands at +31% before Masterworking.
Do not confuse the two Movement Speed options. Natural Motion can also roll Movement Speed for a few seconds after killing an Elite. That number can look much larger, but it is temporary. For these “god boots,” the target is the permanent Movement Speed line.
Step 7: Masterwork to Quality 25 and Put the Capstone Bonus on Movement Speed
Masterwork the boots to Quality 25. Every quality increase raises the affixes, and the final Capstone step gives one affix a much larger bonus. If the Capstone lands on Intelligence, Armor or Maximum Life, reroll it. The goal is for the big final bonus to land on one of the two Movement Speed lines.
At Quality 25, one Movement Speed line has received the Masterwork Capstone bonus. This version shows 48% + 38%, still 86% combined.
There is a useful detail here: the Capstone can land on either Movement Speed line. In one version of the craft, the base Greater Affix becomes 48% while the temper sits at 38%. After another Capstone reroll, the final example becomes 36% base plus 50% tempered Movement Speed. The total remains roughly the same because both lines are receiving the same quality progression and one of them gets the large final bonus.
If you are short on Masterworking materials, our feature on why so much of Diablo IV’s endgame still funnels players back toward The Pit and material farming explains why finishing a near-perfect item can take longer than finding the base item itself.
Step 8: Add the Legendary Aspect Last
Once the affixes, temper and Masterworking are where you want them, imprint the Legendary Aspect your build needs. The example uses Aspect of Shredding Blades because it belongs to the build shown during the craft. Your boots do not need that specific Aspect. The important rule is to finish the expensive stat work first and add the build-specific power when the item is already worth keeping.
Also be very careful with Transfiguration. Some Transfiguration outcomes can make an item Unmodifiable, which can close the door on later crafting. If you plan to keep changing the boots, do not lock them prematurely.
That warning is not theoretical. We have already covered players who turned near-perfect Greater Affix items into unmodifiable crafting dead ends. Crafting order matters more in Season 15 than it did when “upgrade the item” meant clicking one button at the Blacksmith.
The finished boots: Quality 25, strong supporting stats, +36% Greater Affix Movement Speed, +50% tempered Movement Speed and a build-specific Legendary Aspect.
Common Mistakes to Avoid
Starting with ordinary Movement Speed instead of a Greater Affix. The whole ceiling of this craft comes from the starred Movement Speed base.
Using Chaotic Reroll when you meant to use a controlled recipe. Cube crafting is powerful enough that one careless click can turn a good base into a salvage candidate.
Accepting temporary Movement Speed after killing an Elite when your goal is permanent speed.
Spending all your materials on perfect Armor or main-stat values before the important Movement Speed temper succeeds.
Transfiguring too early and making the item Unmodifiable before the craft is finished.
Ignoring the 200% Movement Speed cap. If the rest of your build already reaches it, use the boots to free another slot rather than stacking dead speed.
Why These Boots Are Worth the Trouble
An 80%+ Movement Speed boot slot changes more than how quickly you run between packs. It can remove the need for Movement Speed elsewhere, make farming routes dramatically smoother and let a build hit the normal speed cap without relying on temporary buffs. The real lesson, though, is the crafting process. Season 15 lets a single excellent Greater Affix become the foundation for an item that would once have required an absurdly lucky natural drop.
That is also the tension at the heart of modern Diablo IV loot. As we argued in our feature on players wanting drops to feel exciting again, the game now gives us extraordinary control after an item drops. These boots are the good version of that philosophy: the rare part is finding the right foundation, and the rest is a deliberate project.
The short version: find the GA Movement Speed base, strip the junk, rebuild the supporting affixes, protect one line with Enchanting, polish the remaining values, land a Greater Natural Motion temper, Masterwork to Quality 25 and reroll the Capstone until Movement Speed gets the big bonus.
The result can reach 86% Movement Speed from one pair of boots. Sanctuary has many complicated problems. Walking slowly no longer needs to be one of them.
