Diablo 4 Transfiguration Guide: Tuning Prisms, Outcomes and Risks

In Diablo 4, Transfiguration is the last step you take in crafting your item. This process runs through the Horadric Cube, rolls one powerful random bonus onto a finished piece, and in almost every case locks the item permanently.

This guide explains every possible outcome, both Tuning Prisms and how the timing works so you know exactly what to expect. Players may remember this system as Sanctification.

Transfigure Your Item

In order to transfigure your piece of gear, you place a fully finished item into the Cube with Volatile Primordial Dust.

Volatile Primordial Dust

Legendary Crafting Material

---

A special material used in the Horadric Cube to Transfigure Items.

Collected from:

Cube Spoils in War Plans

Cache Rewards from The Tree of Whispers

Elite monsters

Undercity of Kurast

Crystalized in such volume and purity, the stuff of creation radiates dangerous energy.

The item gains one random bonus from a pool of outcomes and then becomes Unmodifiable. This means no more tempering, masterworking, enchanting, or any other Horadric Cube modification. You can, however, still swap out your runes or gems from the slots (but you cannot add additional slots, so make sure those are on your items before you transfigure it).

There is one way to escape from being locked. Roughly 1 in 16 transfigurations leave the item modifiable, so that means that you can transfigure it AGAIN. If you are really lucky, you can end up in a situation where you are chaining lucky modifiable outcomes, and this is how the truly absurd endgame items get made. But this is pure Diablo 4 lottery.

The Different Outcomes

Transfiguration can lead to one of the following outcomes:

• Bonus Affix: an extra affix is added on top of the item's 4 usual affixes. This can include class skill-rank affixes (+2 to 3 ranks to a skill category, rising to +4 to 6 for Ultimate ranks on two-handed weapons).

• Greater Affix: this upgrades one of the item's affixes to GA status.

• Replace Affix: this swaps an affix for a new one.

• Indestructible: the item no longer loses durability.

• Item Quality Bonus: It stacks with the Masterworking Quality, and you can obtain an additional 1 to 15 quality on your item.

These are the current possible outcomes, without using the additional Prisms.

The Two Transfiguration Tuning Prisms

When you transfigure, you can add one of two different Tuning Prisms in the Horadric Cube.

Using Entropic Tuning Prismguarantees a useful outcome by removing the risky results from the pool. You will not roll Indestructible, Replace Affix, or Greater Affix outcomes, and the Bonus Affix options are restricted to a few more generic affixes. The item also always ends up unmodifiable. It is a good choice for good gear you know you will use, but not for items you are trying to perfect.

Kullean Tuning Prism can only be used on Amulets, and it imprints an additional random Utility Aspect onto your neck piece. It can be rerolled as often as you like and does not lock the amulet from being modified. The goal is to always use the Kullean Prism first, and regular transfiguration second, and never the other way around.

Keep in mind that if you get an Aspect that you already have on another piece of gear in your build, one of them will be greyed out, so you either have to reroll the second one on your Amulet, or you have to swap out the other Aspect.

When to Transfigure

The timing is very important when it comes to transfiguration. Here is what you need to check before you ahead and transfigure your item:

• The item has a tempered affix, preferably rolled to a Greater Affix

• Its enchantment is done, and you are satisfied with it

• Masterworking is at Quality 25 with a Capstone on an affix that matters to your build

• Sockets are added

• The right Aspect is imprinted with its max roll

If any of those are not done, stop. Transfiguration is a finishing step, and the most common way players brick great items.

The One Exception When to Transfigure First

There is what the pro-players are showing. You transfigure first, then do everything else, and then transfigure again.

Basically, leaderboard players run an inverted play on new looted items. This implies using bare items where you transfigure the base FIRST, hoping for an outcome without the Unmodifiable tag (roughly 1 in 16 cases.)

If the base stays modifiable, you now hold an item with a free bonus and every system still available, so you can run the full crafting steps on it: temper, enchant, masterwork, sockets, Aspect, and transfigure a second time at the end. The cost is Volatile Primordial Dust, patience as well as a lot of Common, Magic or Rare bases. But the payoff is an item wearing two transfiguration bonuses, which is very strong. It only works on items that you consider disposable. Never attempt this on an item you cannot afford to lock.

You can do this once you already have a perfect item with one transfiguration on it. You then use other drops to try and get an even better item. That is the only small exception to the usual crafting order.
