If you’ve burned through a pile of Kullean Tuning Prisms in Diablo 4 hoping for a juicy damage aspect and instead got the same utility rolls over and over again, yeah — players are running into the exact same thing right now.
Since the latest Vessel of Hatred updates, Diablo 4’s new amulet transfiguration system has been causing a ton of confusion across Reddit, Blizzard forums, and Discord communities. Some players say offensive aspects never appear, while others are noticing rolls that somehow land below the listed minimum values.
After a lot of community testing, the current answer seems to be: part of this is intended… and part of it probably isn’t.

Why Are Kullean Tuning Prisms Only Rolling Utility Aspects?
This is the biggest complaint players have with the system right now.
Many Diablo 4 players report spending 20, 30, or even more rerolls trying to hit offensive effects on their second necklace aspect slot, only to keep seeing:
- utility effects,
- cooldown-related bonuses,
- defensive aspects,
- resource management perks,
- and support-style rolls.
At first, most players assumed the system was bugged. But after weeks of testing, the community now believes Kullean Tuning Prisms are intentionally limited to a smaller aspect pool.
Can You Roll Damage Aspects With Kullean Tuning Prisms?
Right now, it doesn’t look like it.
Most reports suggest the system currently excludes:
- pure DPS aspects,
- major offensive multipliers,
- and several high-damage legendary powers.
So if your goal was stacking a second damage aspect onto your amulet, the current system probably won’t let you do it.
That part appears to be working as designed — even if the game doesn’t explain it very clearly.
Why Are Aspect Rolls Going Below Minimum?
This is where things start looking genuinely broken.
Players across Diablo 4 communities are reporting:
- aspect values lower than the tooltip minimum,
- missing amulet scaling bonuses,
- weak rolls that don’t match displayed ranges,
- and even bugged “0 value” interactions on some effects.
Normally, amulets in Diablo 4 receive boosted aspect scaling compared to other gear slots. The theory right now is that Kullean Tuning Prisms may be rolling the base aspect internally while still showing the boosted amulet tooltip range.
In simple terms:
the game may be displaying one range while secretly calculating another.
That would explain why some rerolls look mathematically impossible.
The problem is that several players also claim the weaker values affect gameplay itself, not just the UI. Because of that, most of the community currently considers the “below minimum” rolls to be a real Diablo 4 bug rather than just a visual issue.
There’s Also a Risky Re-Imprinting Bug
Unfortunately, the problems don’t stop there.
One of the most serious Kullean Tuning Prism bugs players are warning about involves re-imprinting.
According to multiple reports, if you:
- use a Kullean Tuning Prism on an amulet,
- then later change the original aspect,
the item can become partially broken.
Players claim this can cause:
- the secondary aspect to disappear,
- rerolls to become permanently stuck,
- transfiguration to stop working,
- or the necklace to display “Cannot Transfigure this item.”
In some cases, players say the amulet became unusable for future prism crafting entirely.
That’s why many endgame players currently recommend avoiding prisms on expensive gear unless the item is already fully finalized.
Should You Use Kullean Tuning Prisms Right Now?
At the moment, probably only if:
- you’re okay with utility-focused rolls,
- your amulet is already finished,
- and you don’t plan to re-imprint it later.
If you’re chasing high-end offensive combinations or trying to min-max damage, most players suggest saving your prisms until Blizzard patches the system.
Right now, the risk-to-reward ratio simply isn’t great.
Final Thoughts
The Diablo 4 Kullean Tuning Prism system feels like a mix of hidden restrictions and genuine bugs. Utility-only aspect pools seem intentional based on community testing, but rolls landing below minimum values — along with the re-imprinting issues — are being reported far too often to ignore.
For now, the safest approach is simple:
use prisms carefully, avoid modifying the item afterward, and don’t expect offensive aspect rerolls to suddenly appear no matter how many materials you throw at it.
