PoE Suffixes Cannot Be Changed Guide: Unlock Location, Cost, Scouring & Crafting

Suffixes Cannot Be Changed is one of the most useful meta-crafting modifiers in Path of Exile. It allows players to preserve valuable suffixes while removing, rerolling, or replacing unwanted prefixes.

The modifier costs 2 Divine Orbs, occupies a prefix slot, and is unlocked in the unique map Oba’s Cursed Trove.

However, it does not protect suffixes against every crafting method. Understanding which currency items respect the modifier is essential for avoiding expensive crafting mistakes.

This guide explains how to unlock Suffixes Cannot Be Changed, how it works with Orbs of Scouring, Chaos Orbs, Harvest crafting, Veiled Chaos Orbs, and other crafting methods, and how to use it effectively in PoE 3.29.

1. What Does Suffixes Cannot Be Changed Do in PoE?

Suffixes Cannot Be Changed is a crafted meta-modifier that prevents existing suffixes from being modified or removed by supported crafting methods.

Rare equipment normally has up to three prefixes and three suffixes.

When Suffixes Cannot Be Changed is active:

• Existing suffixes are protected from supported rerolling and removal effects.
• Prefixes remain available for modification.
• The meta-modifier occupies one prefix slot.
• The modifier itself can be removed by crafting methods that reroll or remove prefixes.
• New suffixes can still be added if empty suffix slots are available.
• Certain crafting methods bypass the modifier or cannot be used while it is present.

For example, suppose a rare amulet has three desirable suffixes but undesirable prefixes.

By crafting Suffixes Cannot Be Changed and applying an Orb of Scouring, you can remove the prefixes while preserving those three suffixes.

You can then rebuild the prefixes without starting the entire crafting process again.

Important: The modifier protects existing suffixes, but it does not freeze empty suffix slots. A reforge can still add an unwanted suffix if there is space available.

2. Suffixes Cannot Be Changed Recipe, Cost and Unlock Location

The crafting recipe is available through the Crafting Bench after unlocking it in Oba’s Cursed Trove.

How to Unlock Suffixes Cannot Be Changed

1. Obtain an Oba’s Cursed Trove unique map through drops, trading, or other available acquisition methods.
2. Place the map in your Map Device.
3. Enter the map and progress through its connected areas.
4. Clear the required monsters to unlock the passages to subsequent rooms.
5. Continue until you reach the final treasure chamber.
6. Find and interact with the crafting recipe object to unlock Suffixes Cannot Be Changed.
7. Return to your hideout and access your Crafting Bench.
8. Select Suffixes Cannot Be Changed when crafting an eligible item.

Oba’s Cursed Trove features a timed dungeon mechanic. The area eventually becomes fatal, so prioritize progressing through the rooms instead of spending too much time looting.

The map’s level and tier can vary across Atlas versions and map series. Older guides listing tiers 1, 4, 8, 12, and 16 should not be treated as a permanent map-tier requirement.

Once unlocked, the recipe can be used through the Crafting Bench whenever you have the necessary currency and an eligible item.

3. Is Suffixes Cannot Be Changed a Prefix or Suffix?

Suffixes Cannot Be Changed is a prefix, not a suffix.

This is one of the most frequently misunderstood aspects of PoE meta-crafting.

The modifier is called Suffixed, but its generation type is Prefix.

Conversely, Prefixes Cannot Be Changed is a suffix.

Because Suffixes Cannot Be Changed occupies a prefix slot, the item must have an available prefix slot before you can apply it.

If all three prefix slots are occupied on a rare item, you cannot directly craft the modifier.

You must first create an available prefix slot using an appropriate crafting method.

If doing so requires randomly removing a modifier, there is a risk of losing a valuable affix before the protection is applied.

4. Which Crafting Methods Respect Suffixes Cannot Be Changed?

Not every crafting method interacts with meta-modifiers in the same way.

The following table summarizes important interactions in Path of Exile 1.

A distinction is necessary between three situations:

Respected: The crafting method follows the restriction imposed by Suffixes Cannot Be Changed.

Ignored: The crafting method can operate without following the protection.

Usage blocked: The game prevents the crafting method from being used on an item with the applicable metamod.

The last two situations are not equivalent. For example, a Fossil does not simply bypass the protected suffixes during a normal attempt. Its use is prevented while the relevant metamod is present.

5. Suffixes Cannot Be Changed + Orb of Scouring

Using an Orb of Scouring with Suffixes Cannot Be Changed is one of the most straightforward methods of preserving valuable affixes.

Normally, an Orb of Scouring removes all explicit modifiers from a magic or rare item.

However, it respects meta-crafting protection.

When Suffixes Cannot Be Changed is active, an Orb of Scouring:

• Preserves the protected suffixes.
• Removes unprotected prefixes.
• Removes the Suffixes Cannot Be Changed modifier itself.
• Leaves implicit modifiers and other normally unaffected item properties intact.

Step-by-Step Scouring Example

Imagine a rare ring has the following modifiers.

Prefixes:

• +65 to Maximum Life
• +40 to Maximum Mana

Suffixes:

• +45% to Fire Resistance
• +42% to Cold Resistance
• +35% to Chaos Resistance

Suppose you want to keep all three resistances but replace the prefixes.

Step 1: Confirm the ring has an empty prefix slot.

Step 2: Craft Suffixes Cannot Be Changed for 2 Divine Orbs.

Step 3: Apply an Orb of Scouring.

Step 4: The existing prefixes and the crafted metamod are removed.

Step 5: The three resistance suffixes remain.

You now have a ring with three protected desirable suffixes and available prefix slots for further crafting.

Does Scouring Keep the Item Rare?

It depends on how many modifiers remain.

If an Orb of Scouring leaves only one explicit modifier, the item becomes magic. When at least two explicit modifiers remain, it stays rare.

This matters when planning how to rebuild an item.

Crafting tip: Suffix locking followed by scouring is particularly useful when the item already has two or three valuable suffixes that would be expensive to reproduce.

6. Suffixes Cannot Be Changed + Chaos Orb

A Chaos Orb normally reforges a rare item with new random modifiers.

When Suffixes Cannot Be Changed is crafted onto the item, the Chaos Orb respects the existing suffixes.

The general outcome is:

1. Existing protected suffixes remain.
2. Unprotected prefixes are rerolled.
3. The crafted Suffixes Cannot Be Changed prefix is removed.
4. New prefixes are generated.
5. Additional suffixes may be generated if suffix slots are available.

For example, if an item has three completed suffixes, a Chaos Orb cannot add another suffix because all three suffix slots are already occupied.

This creates a way to reroll prefixes without losing the completed suffixes.

However, there is an important limitation.

The protection is not permanent.

Once the Chaos Orb removes the crafted prefix, the item is no longer protected.

To repeat the process, you must craft Suffixes Cannot Be Changed again, spending another 2 Divine Orbs.

Is Chaos Spamming With Suffixes Cannot Be Changed Worth It?

Usually, repeatedly applying the metamod and using Chaos Orbs is expensive.

A single protected Chaos Orb attempt costs at least:

• 2 Divine Orbs for the metamod.
• 1 Chaos Orb for the reforge.

A second attempt generally requires another 2 Divine Orbs, assuming the item remains eligible for the craft.

If a reforge fills all prefix slots, you may need additional steps before applying the metamod again.

Consider Harvest crafting, Veiled crafting, or other techniques when they offer better odds of obtaining a desired prefix.

7. Suffixes Cannot Be Changed + Veiled Chaos Orb

Veiled Chaos Orbs are available again in Path of Exile 1.

They were reintroduced in version 3.26.0 as separate currency items from Veiled Exalted Orbs.

A Veiled Chaos Orb reforges a rare item with new random modifiers while guaranteeing a veiled modifier.

Like a regular Chaos Orb, it respects Suffixes Cannot Be Changed.

How to Use a Veiled Chaos Orb

1. Begin with a rare item containing desirable suffixes.
2. Ensure the item has an available prefix slot.
3. Craft Suffixes Cannot Be Changed for 2 Divine Orbs.
4. Use a Veiled Chaos Orb.
5. The existing protected suffixes are preserved.
6. The prefixes are reforged, and a veiled modifier is generated.
7. Unveil the modifier through Jun and select the best available option.

If all three suffix slots are occupied, the newly generated veiled modifier must occupy an available prefix slot.

This makes suffix locking especially useful when targeting veiled prefixes.

However, the outcome is not guaranteed to include your desired modifier. The available unveil options and other generated prefixes remain subject to randomness.

Veiled Chaos Orb vs. Veiled Exalted Orb

These two currencies have different effects.

Veiled Chaos Orb

• Reforges a rare item with new random modifiers.
• Guarantees one veiled modifier.
• Respects existing protected suffixes.
• Can be obtained from Syndicate Safehouse Leaders.

Veiled Exalted Orb

• Removes one random modifier.
• Adds one random veiled modifier.
• Respects Prefixes Cannot Be Changed and Suffixes Cannot Be Changed during modifier removal.
• Can drop from Catarina, Master of Undeath.

A Veiled Exalted Orb is often used when players want to retain more of an item’s existing modifiers rather than rerolling all unprotected affixes.

Nevertheless, it carries risk because the removed modifier is random among eligible modifiers.

Important: Old guides that describe a Veiled Orb, Veiled Chaos Orb, and Veiled Exalted Orb as the same item may be outdated. Always verify which currency is required before following a crafting recipe.

8. Suffixes Cannot Be Changed + Harvest Crafting

Harvest crafting provides several ways to modify rare items while preserving existing suffixes.

For example, a Harvest reforge that guarantees a particular modifier type can respect Suffixes Cannot Be Changed.

This allows players to target certain prefix modifier types without rerolling their existing valuable suffixes.

Example: Harvest Reforge With Locked Suffixes

Suppose you have rare boots with:

• Three desirable suffixes.
• Unwanted prefixes.
• One available prefix slot.

You can:

1. Craft Suffixes Cannot Be Changed.
2. Open the Horticrafting Station.
3. Select an appropriate Harvest reforge.
4. Apply it to the item.
5. Preserve the existing suffixes while generating new eligible prefixes.

The exact result depends on the item base, modifier tags, item level, and chosen Harvest option.

A Harvest reforge is not guaranteed to produce a particular high-tier modifier just because the suffixes are protected.

Does Harvest Always Respect Suffixes Cannot Be Changed?

No.

Different Harvest crafts have different interactions.

Common reforges respect existing protected suffixes. Certain specialized operations, such as fracturing, ignore standard metamod protection.

Additionally, Harvest crafting may fill previously empty prefix or suffix slots where the selected operation permits it.

Therefore, check the exact Harvest option rather than assuming every Harvest craft behaves identically.

9. Suffixes Cannot Be Changed + Orb of Annulment

An Orb of Annulment removes one random eligible explicit modifier.

When Suffixes Cannot Be Changed is active, the Orb of Annulment cannot remove existing protected suffixes.

However, it can remove an eligible prefix, including the crafted metamod itself.

Example

Consider an item containing:

Prefixes:

• +70 Maximum Life
• +50 Maximum Mana
• Suffixes Cannot Be Changed

Suffixes:

• +40% Fire Resistance
• +40% Cold Resistance
• +35% Chaos Resistance

Using an Orb of Annulment can remove:

• The Maximum Life prefix.
• The Maximum Mana prefix.
• The Suffixes Cannot Be Changed prefix.

It cannot remove the protected resistance suffixes.

There is no guarantee that the Orb will remove the particular unwanted prefix you selected mentally.

If it removes Suffixes Cannot Be Changed, the remaining suffixes are no longer protected.

Should You Annul or Scour?

Use an Orb of Scouring when you want to remove all prefixes while preserving suffixes.

Consider an Orb of Annulment when you want to remove one unwanted prefix while potentially retaining other desirable prefixes.

Scouring is generally more predictable for clearing all prefixes.

10. Does Suffixes Cannot Be Changed Work With Divine Orbs?

Yes. Divine Orbs respect the metamod.

A Divine Orb normally randomizes numerical values of eligible explicit modifiers within their existing ranges.

When Suffixes Cannot Be Changed is active, the existing suffix values are protected.

This allows the Divine Orb to reroll eligible prefix values without changing protected suffix rolls.

However, Suffixes Cannot Be Changed itself costs 2 Divine Orbs, so this can become an expensive strategy.

Before attempting numerical optimization, confirm that the item has enough improvement potential to justify the additional cost.

11. Does Suffixes Cannot Be Changed Work With Essences and Fossils?

No. Standard Essence and Fossil rerolling cannot normally be performed on an item carrying this metamod.

This is an important correction to many older PoE crafting guides.

Essences and Fossils are different from Chaos Orbs and Harvest reforges.

When an applicable metamod is present, the game prevents their normal use rather than allowing the crafting attempt to preserve the desired suffixes.

Recommended Crafting Order

If you want a specific Essence modifier:

1. Start with the appropriate item base.
2. Apply the desired Essence until you obtain a suitable combination of modifiers.
3. Develop the suffixes or prefixes you intend to keep.
4. Apply Suffixes Cannot Be Changed afterward.
5. Use supported crafting methods to continue the item.

The same general principle applies to Fossil crafting.

Use Essences or Fossils earlier in the crafting process, then use the metamod to protect the finished suffixes.

12. Suffixes Cannot Be Changed and Eldritch Crafting

Eldritch crafting requires particular attention because it follows different rules from standard crafting currencies.

Eldritch Chaos Orb

An Eldritch Chaos Orb can reroll prefixes or suffixes depending on which Eldritch implicit influence is dominant.

Unlike a regular Chaos Orb, it ignores standard Prefixes Cannot Be Changed and Suffixes Cannot Be Changed metamods.

Therefore, do not assume that a crafted suffix lock will protect your modifiers from an Eldritch Chaos Orb.

Instead, use the appropriate Eldritch dominance to target the desired affix group.

For example:

• Searing Exarch dominant: Eldritch Chaos Orb rerolls prefixes.
• Eater of Worlds dominant: Eldritch Chaos Orb rerolls suffixes.

If your goal is to retain valuable suffixes while rerolling prefixes, Searing Exarch dominance is the relevant condition.

Eldritch Orb of Annulment

Eldritch Orbs of Annulment respect prefix/suffix metamods, but their modifier removal is also controlled by Eldritch dominance.

They should not be confused with Eldritch Chaos Orbs.

When Is Eldritch Crafting Better?

For eligible helmets, gloves, boots, and body armour with the required Eldritch implicits, Eldritch currency can provide an alternative method of targeting prefixes or suffixes.

This may reduce the need to repeatedly pay 2 Divine Orbs for suffix locking.

However, Eldritch crafting is not available on every item class, and its results depend on the item and selected currency.

13. Crafting Methods That Can Bypass Suffix Protection

Suffixes Cannot Be Changed is powerful, but it is not universal protection.

Some advanced crafting methods ignore the restriction.

Awakener’s Orb

Awakener’s Orbs ignore standard metamod protection.

Do not expect Suffixes Cannot Be Changed to preserve all existing suffixes when combining influenced items.

Orb of Unravelling

The Orb of Unravelling, introduced in version 3.26, interacts with Memory Strands and attempts to upgrade modifier tiers.

It does not respect Prefixes Cannot Be Changed or Suffixes Cannot Be Changed.

This makes it unsuitable for any strategy that relies on these metamods to guarantee suffix preservation.

Harvest Fracturing

Harvest fracturing does not respect the standard prefix/suffix locking rules.

Applying a suffix lock does not guarantee that a particular suffix will be selected or preserved by the fracturing process.

General Rule

Never assume a crafting effect respects a metamod solely because it modifies explicit affixes.

Check the specific currency interaction before using expensive or potentially destructive crafting methods.

14. Best Ways to Use Suffixes Cannot Be Changed

There are several practical situations where this metamod is especially valuable.

Method 1: Preserve Three Valuable Suffixes

This is one of the most reliable applications.

Once you obtain three desirable suffixes, use Suffixes Cannot Be Changed and an Orb of Scouring to clear unwanted prefixes.

You can then rebuild the prefixes while retaining your completed suffixes.

Method 2: Target a Veiled Prefix

If all three suffix slots are filled, Suffixes Cannot Be Changed can help make a Veiled Chaos Orb produce a veiled prefix.

The specific unveiled modifier remains random, but the completed suffixes are preserved.

Method 3: Harvest Reforge Prefixes

Use suffix locking before a compatible Harvest reforge to generate a desirable prefix modifier.

Check the available modifier pool before spending currency.

Method 4: Safely Remove an Unwanted Prefix

An Orb of Annulment can remove an eligible prefix without deleting an existing protected suffix.

The risk is that it may also remove the suffix-locking modifier.

Method 5: Prepare Influenced Equipment

Suffix locking can be useful during certain influenced-item crafting processes, particularly when preparing modifiers for a subsequent Orb of Dominance interaction.

However, not every influence-related crafting method respects metamods.

Always verify the interaction before proceeding.

15. Suffixes Cannot Be Changed vs. Prefixes Cannot Be Changed

These two metamods perform opposite functions.

Choose Suffixes Cannot Be Changed when the suffixes are the most valuable part of your item.

Choose Prefixes Cannot Be Changed when you want to keep powerful prefixes while replacing suffixes.

Both are expensive crafting tools designed to preserve completed portions of an item.

16. All PoE Meta-Crafting Recipe Locations

Path of Exile 1 has five standard meta-crafting modifiers.

These recipes are valuable to unlock when progressing into advanced endgame crafting.

Depending on the item, multiple meta-crafting modifiers can be combined using the appropriate crafting setup.

However, the item must have sufficient modifier capacity, and standard crafted-modifier limits still apply.

For example, Can have up to 3 Crafted Modifiers occupies one of the allowed crafted-modifier slots.

Planning the number and position of prefixes and suffixes is essential before attempting a complex combination.

17. Common Suffixes Cannot Be Changed Mistakes

Mistake 1: Thinking It Is a Suffix

Despite its name, Suffixes Cannot Be Changed is a prefix.

You must have an available prefix slot to apply it.

Mistake 2: Assuming All Crafting Methods Respect It

Some currencies ignore metamods entirely.

An Awakener’s Orb or Eldritch Chaos Orb should not be treated like an ordinary Chaos Orb.

Mistake 3: Forgetting the Metamod Is Removed

An Orb of Scouring, Chaos Orb, or compatible reforge can remove the crafted suffix-locking prefix.

The protection is no longer active afterward.

Mistake 4: Trying to Use Essences or Fossils

Standard Essence and Fossil rerolls are blocked while the relevant metamod is present.

Apply these crafting methods earlier instead.

Mistake 5: Locking Suffixes Too Early

If your item only has one desirable suffix, spending 2 Divine Orbs to protect it may be inefficient.

Suffix locking is usually more valuable when preserving multiple rare or expensive modifiers.

Mistake 6: Ignoring Empty Suffix Slots

The metamod protects existing suffixes.

It does not prevent supported crafting methods from adding a new suffix to an available slot.

Mistake 7: Repeatedly Paying for Inefficient Reforges

Each time the crafted metamod is removed, applying it again costs another 2 Divine Orbs.

Consider the total expected crafting cost before attempting multiple rerolls.
