In Aion 2, the item commonly called a “refining stone” is generally listed as an Enhancement Stone. It raises an equipment item’s enhancement level and is normally spent together with Kina (also spelled Kinah in some guides). It is not a universal upgrade currency: Breakthrough Stones extend an enhancement cap, slot-specific Enhancement Scrolls unlock or support certain upgrades, Manastones and Spirit Stones change socketed properties, and Arcana crystals belong to a separate progression system.
The exact names, caps, rates, slot requirements and failure rules can vary by region and patch. The AION 2 Wiki warns that many detailed figures come from Korean and Taiwanese service and may not match a global build (AION 2 Wiki). Confirm the current item tooltip and enhancement screen in your client before committing scarce materials.

What a Refining (Enhancement) Stone Actually Does
Enhancement Stones are the ordinary, item-level material for increasing the visible enhancement level of weapons, armor and accessories. An attempt typically consumes stones and Kina/Kinah. This is the “make the number on this piece higher” path, rather than a way to add a socket, lock an Arcana trait or pass a normal cap.
Guides use “Enhancement Stone,” not “Refining Stone,” as the basic item name. If a translation, player chat or older guide says refining stone, inspect the icon and the in-client description to ensure it is the same item. Names can differ between localizations, but the function is more important than the nickname: the ordinary stone is accepted by the enhancement-level panel and is not automatically accepted by every other upgrade window.

Equipment-system guidance describes stones and currency as the funding for enhancement, while dungeon and expedition activities can supply stones or gear. Treat those acquisition statements as guide descriptions rather than a guarantee for every region or patch (AION 2 Help). The reliable test is the current item tooltip and the reward list shown by your client.
What the stone changes
An Enhancement Stone changes the item’s enhancement level as a whole. It does not, by itself, rewrite a weapon’s socketed statistics, improve an Arcana property, or authorize progression beyond a cap. Those distinctions matter when the interface presents several buttons that all look like “upgrade.” Select the exact equipment system first, then collect the material that system requests.
What it normally costs
Guides describe Kina or Kinah as the currency paid with Enhancement Stones. The spelling varies in published guides, so follow the localization in your wallet and enhancement panel. Budget the currency as a separate resource: even when a stone can later be recovered through extraction or dismantling, the currency spent on attempts is not necessarily returned.

How the Upgrade Materials Differ
| Material or resource | What it upgrades | Typical use or companion requirement | What it is not | Decision question |
|---|---|---|---|---|
| Enhancement Stone | The equipment’s ordinary enhancement level | Used with Kina/Kinah for weapons, armor and accessories | Not a cap-breaker, socket item or Arcana resource | Am I raising the normal number on this item? |
| Breakthrough Stone | Progress beyond the regular enhancement cap | Used when the item has reached the applicable normal limit | Not the material for every routine level | Has the item reached a cap that blocks further levels? |
| Enhancement Scroll | Additional progression for specified equipment slots | Examples in guides include amulets and belts; the affected slots can vary | Not a replacement for Enhancement Stones or currency | Does this slot display a scroll requirement? |
| Manastone | Socketed weapon or armor statistics | Inserted or managed through the socket/property system | Does not simply raise the enhancement number | Am I changing a socketed stat rather than the level? |
| Spirit Stone | Accessory socket/property statistics | Separate accessory counterpart to the Manastone path in the fan-wiki taxonomy | Not an ordinary enhancement stone | Is this an accessory property slot? |
| Theostone | A separate equipment system or tab | Use depends on the current client’s gear rules | Should not be described as the basic enhancement material | Does the Theostone interface, rather than enhancement panel, request it? |
| Mysterious Crystal | Arcana progression | Refines Arcana rather than standard equipment | Not an equipment-level stone | Am I refining an Arcana entry? |
| Pure Crystal | Arcana property management | Locks one Arcana property | Not a socket stone or enhancement-level material | Do I need to preserve one Arcana property? |
| Kina/Kinah | Currency cost | Spent with enhancement attempts according to the guides | Not a material item that raises stats by itself | Can I afford the currency charge as well as the item? |
The wiki’s broad organizing rule is useful: some resources upgrade the item as a whole, while others alter its properties. Its detailed system information is based on Korean and Taiwanese service, so apply that rule cautiously to a global or later build (AION 2 Wiki). The table is therefore a functional map, not a promise that every region uses exactly the same labels, slot list or costs.
Four comparison axes to use in the client
- Target: ordinary level, cap, socketed stat, Theostone system or Arcana property.
- Slot: weapon, armor, accessory or a named slot such as an amulet or belt.
- Companions: Kina/Kinah, a scroll or another item may be required in addition to the main material.
- Risk and recovery: check failure text, possible downgrade, what is consumed and what extraction returns.
Enhancement Stones and Breakthrough Stones
Regular enhancement
Use Enhancement Stones when the enhancement panel asks for the ordinary level-up material. The stone and currency are consumed for the attempt; the item itself is the target. This is the material you spend repeatedly while developing a piece that you expect to keep. A higher enhancement level may be useful for the item’s current role, but the guides do not establish one universal “correct” stopping point for every class or gear tier.
Breaking the cap
A Breakthrough Stone serves a different purpose: it permits progression beyond a normal enhancement ceiling. It should not be substituted for ordinary stones, and ordinary stones should not be stockpiled as though they alone will unlock the next cap. The applicable cap and the exact breakthrough cost are version-sensitive; read the item and equipment panel in the current client.
Think of breakthrough as a gate, not a faster level-up. If the panel is still accepting ordinary Enhancement Stones for the next level, a Breakthrough Stone may be unnecessary. If the panel shows a cap message or explicitly requests breakthrough material, farming more ordinary stones will not remove that gate. Keep the two inventories separate so a cap-extension item is not accidentally spent on a disposable piece.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
A practical sequencing rule
- Raise the item with ordinary Enhancement Stones only while the panel lists normal enhancement requirements.
- Pause at the displayed cap and inspect the breakthrough requirement, including any currency charge.
- Compare the item’s expected lifespan with the value of the breakthrough material.
- Resume ordinary enhancement only after the cap is actually opened and the panel confirms the new requirements.
Where Enhancement Scrolls Fit
Some slots require an Enhancement Scroll in addition to stones and Kina. Guides specifically mention amulets and belts as examples, but do not establish one permanent slot list for every regional build. If the enhancement screen shows a scroll requirement, obtain that companion item before assuming more stones will solve the problem.

A scroll is therefore a slot-specific companion, not a universal substitute. It may be possible to own plenty of stones and still be unable to enhance an amulet or belt because the scroll is missing. Conversely, obtaining a scroll does not remove the ordinary stone or currency charge if those remain listed in the panel.
- Open the equipment enhancement interface and select the exact item.
- Read the required-material row, including any slot-specific scroll.
- Check the currency charge and the current success or failure rule shown by the client.
- Confirm that the scroll belongs to the selected slot or item category.
- Only then confirm the attempt; a stone-only attempt cannot bypass a missing scroll.
Do not infer the slot list from another region, an old video or a different item quality. The guides’ examples establish why scrolls exist, but the live interface determines whether your selected piece needs one.
Socket Stones, Theostones and Arcana Resources
Manastones and Spirit Stones
Manastones are socketed items for weapon and armor statistics in the fan-wiki classification. Spirit Stones are presented there as the accessory counterpart. They add or change properties in a socket path; they do not raise the enhancement level displayed for the gear. Check the current regional terminology, because translations and system names can change.
Socket decisions should be made separately from level decisions. A high-level item can still need a Manastone or Spirit Stone, while a socketed item can remain at a modest enhancement level. When comparing two upgrades, identify whether you are buying more item-level power or changing the distribution of stats. The material, interface and recovery behavior may all differ.
Theostone
Theostone appears as its own equipment system or tab in the guides. The reviewed material does not establish a universal list of applicable gear or a single global cost, so use the current Theostone interface rather than treating it as another name for Enhancement Stone. If an item is listed under a Theostone tab, follow that system’s requirements instead of moving stones into the ordinary enhancement panel.
Mysterious and Pure Crystals
Mysterious Crystal is described as an Arcana-refining resource. Pure Crystal locks one Arcana property. Both belong to Arcana progression and property management, not ordinary weapon, armor or accessory enhancement. Spending either on Arcana will not raise the enhancement number shown on a sword, chest piece or ring.
Arcana resources also illustrate why “upgrade material” is too broad a category. Mysterious Crystal changes Arcana progression, while Pure Crystal protects a chosen property. Their value depends on the Arcana decision in front of you, not on the item’s ordinary enhancement cap.

GEGEBASE’s guide says its “current Global” reference guarantees enhancement through +10. It reports that attempts above +10 can fail, consume the required materials and leave the equipment intact without lowering its enhancement level (GEGEBASE). This is a guide claim, not independently confirmed official documentation in the material reviewed, so do not assume the +10 threshold or non-destructive behavior applies to every region, patch or item.

The important distinction is between the equipment surviving and the attempt being free. Under that guide’s description, required materials are consumed on failure. A surviving item does not imply that Enhancement Stones, a scroll or Kina/Kinah are refunded. Socketed investments and other property changes should also be treated as separate unless the panel explicitly says they are protected.
Before a risky attempt, record what the panel says about success, consumption and downgrade protection. A failure rule can change with a patch, an item category or a regional implementation. Never infer that socketed investments or currency will be refunded merely because the gear itself survives.
Questions to answer before clicking confirm
- Is the attempt at or above the milestone shown by the current client?
- Which items are consumed whether the attempt succeeds or fails?
- Can the level drop, or does the panel promise that the item remains intact?
- Is a slot scroll consumed along with the stone?
- Does the displayed rule apply to this exact item category?
If any answer is unclear, stop and inspect the tooltip, help text or current patch notes. A guide’s description can orient you, but the live client is the safer authority for a costly click.
Should You Spend Stones on This Item?
The best target is the piece whose benefits will last long enough to justify both stones and unrecovered currency. The equipment guide explicitly recommends balancing investment against an item’s replacement timeline. A weapon-first approach is common for damage-focused characters because weapon improvement can affect offensive output, but it is not universal: class role, item quality, group needs, transfer or inheritance rules and the next planned replacement all matter.
- Keep the item: Enhancement is easier to justify when the piece is high quality, difficult to replace or expected to transfer to a later build.
- Replace it soon: Stop at a modest level when a dungeon, expedition or planned progression step is likely to supply a better item shortly.
- Check inheritance first: If the client offers transfer or inheritance, read exactly which enhancement, socket and currency investments carry over.
- Reserve breakthrough materials: Do not spend a cap-extension item on gear you already expect to discard.
- Budget Kina separately: A stone may be recoverable while the currency charge is not.
- Match the role: Damage-focused characters often look at weapons first, but defensive, support or progression bottlenecks can make armor or an accessory the more sensible target.
A simple replacement test
Ask three questions before enhancing: How long will this item be equipped? Can its investment move to another item? What is the cost of waiting for the next dungeon or expedition reward? If the answer to the first two is uncertain and an upgrade source is near, conserve stones and currency. If the item is difficult to replace and transfer rules preserve the investment, a larger commitment may be easier to justify.
Recovery, Extraction and Dismantling
The reviewed guides identify extraction or dismantling as a way to recover Enhancement Stones. They also caution that Kina and socketed investments are not necessarily returned. Because this behavior is volatile and may be version-specific, inspect the exact confirmation window in your client before dismantling anything valuable.
- Open the extraction or dismantling screen, not the normal enhancement screen.
- Preview the returned items and the items explicitly listed as lost.
- Confirm whether the preview distinguishes Enhancement Stones from currency, scrolls and socketed items.
- Check that the gear is not needed for transfer, collection, a set effect or another character.
- Capture the displayed result before confirming if the return rules are unclear.
Recovery is not a reason to enhance recklessly. Even if stones are returned, the currency charge may remain unreimbursed, and a socketed Manastone or Spirit Stone may not come back. Treat extraction as a possible partial recovery, not a guarantee of a full refund.

Do not farm a material solely because its name sounds similar. First identify whether the bottleneck is an ordinary level, a cap breakthrough, a slot scroll, a socket property or an Arcana property. That distinction prevents spending stamina or currency on an item the enhancement panel will not accept.
Match the farm to the bottleneck
- Ordinary level blocked: look for the Enhancement Stone source listed by the client and reserve enough Kina/Kinah for attempts.
- Cap blocked: search specifically for Breakthrough Stones rather than increasing the ordinary-stone stockpile.
- Slot blocked: identify the required Enhancement Scroll and its listed activity or shop.
- Socket blocked: use the Manastone or Spirit Stone path for the applicable gear type.
- Arcana blocked: follow the Mysterious Crystal or Pure Crystal requirement shown by the Arcana interface.
Dungeon and expedition rewards can also provide replacement gear. When a likely replacement is close, compare its expected quality with the cost of enhancing the current item before spending scarce materials.

The sources available for this comparison are fan guides rather than an official NCSOFT document that defines one current global ruleset. The AION 2 Wiki explicitly warns that its detailed figures come from Korean and Taiwanese service, while GEGEBASE labels its +10 description as current Global documentation without linking primary support. Names, rates, caps, acquisition routes and failure behavior can therefore differ.

- Check current patch notes for cap, failure or inheritance changes.
- Do not import a Korean, Taiwanese or older global number into another build without confirmation.
- Check whether a translation uses “Kina” or “Kinah” and whether “refining” is merely a player nickname for Enhancement Stone.

Common Spending Mistakes
- Using the wrong stone: buying ordinary Enhancement Stones when the item is capped and needs a Breakthrough Stone.
- Ignoring the slot: assuming a belt or amulet will enhance without the scroll displayed by its panel.
- Confusing properties with levels: inserting a Manastone or Spirit Stone when the goal is a higher enhancement number.
- Mixing Arcana and gear: spending Mysterious or Pure Crystals expecting a weapon or armor level increase.
- Counting only the item cost: forgetting the Kina/Kinah charge or assuming it is refunded after extraction.
- Trusting another region’s cap: applying a Korean, Taiwanese or older global threshold to the current client.
- Enhancing before checking replacement: investing in gear that a dungeon or expedition is likely to replace soon.
- Assuming failure is harmless: reading “item remains intact” as “nothing is consumed.”
- Dismantling too quickly: overlooking transfer, collection, set or socket value before confirming extraction.
A Practical Decision Checklist
- Identify the system: ordinary enhancement, breakthrough, slot scroll, socket property, Theostone or Arcana.
- Confirm the required items: Enhancement Stone, Breakthrough Stone, scroll, Manastone, Spirit Stone, crystal or another client-listed resource.
- Check the currency: note the Kina/Kinah charge and whether it is consumed on failure.
- Assess longevity: compare the item’s expected use with your next replacement, transfer or inheritance opportunity.
- Read the failure text: verify whether the item can fail, downgrade, remain intact or lose materials.
- Review recovery: inspect extraction or dismantling returns before investing socketed materials.
- Confirm region and patch: use the live client’s labels and rules over an older guide.
- Set a stopping point: decide in advance how much currency and which materials you are willing to spend.
- Recheck after success: confirm the new level, remaining cap and any newly unlocked requirement before starting another attempt.
Key Takeaway
Enhancement Stones are the basic level-raising material, normally paired with Kina/Kinah. Breakthrough Stones extend a cap; Enhancement Scrolls support particular slots; Manastones and Spirit Stones alter sockets; Theostones use a separate equipment system; and Mysterious and Pure Crystals govern Arcana. Choose by function and item lifespan, not by the generic idea that every “upgrade material” is interchangeable. When a guide and the client disagree, follow the current item tooltip, enhancement panel and patch notes for your region.
Frequently Asked Questions
Are refining stones and Enhancement Stones the same item in Aion 2?
“Refining Stone” is commonly used informally, while the guides identify the basic level-raising item as an Enhancement Stone. Verify the icon and tooltip in your client.
Do Enhancement Stones work for every gear upgrade?
No. They handle ordinary enhancement levels. Breakthroughs, slot scrolls, sockets, Theostone and Arcana use separate systems or materials.

Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minuteWhat is the difference between an Enhancement Stone and a Breakthrough Stone?
An Enhancement Stone raises ordinary enhancement levels. A Breakthrough Stone is used to progress beyond an applicable normal cap; it is not a substitute for routine level-up stones.
Best Value
Which gear slots may need an Enhancement Scroll?
Guides give amulets and belts as examples, but the complete list can vary by regional build and patch. Select the item and read the live enhancement panel.
Are Manastones and Spirit Stones another kind of Enhancement Stone?
No. Manastones and Spirit Stones belong to socket or property systems. The fan-wiki taxonomy places Manastones with weapons and armor and Spirit Stones with accessories; neither simply raises the enhancement number.
What do Mysterious Crystal and Pure Crystal do?
Mysterious Crystal is described as refining Arcana. Pure Crystal locks one Arcana property. They are Arcana resources, not ordinary equipment-enhancement materials.
Will failed enhancement destroy or downgrade my gear?
A GEGEBASE guide reports intact, non-downgraded gear for failures above +10 in its current Global reference, but that rule is not independently confirmed as universal. Follow the live client’s failure text and check what materials are consumed.
Do I get my Kina or socket investments back when I dismantle gear?
Guides describe extraction or dismantling as a way to recover Enhancement Stones, while warning that Kina and socketed investments are not necessarily returned. Inspect the current confirmation preview before proceeding.
Should I enhance my weapon first?
Weapon-first spending is common for damage-focused characters, but it is not universal. Class role, item quality, replacement timing, group needs and transfer or inheritance rules should determine the priority.
Where do Enhancement Stones come from?
Equipment guides associate stones or gear with dungeon and expedition activities. Because routes can change, use the material tooltip and current activity rewards panel for your region.

One-click scans. No signup required.
Why do guides show different caps, names or costs?
The AION 2 Wiki says many detailed figures come from Korean and Taiwanese service, while other guides describe a current Global reference. Region, localization and patch can change terminology, rates, caps, slot requirements and failure behavior.
The Bottom Line
Use Enhancement Stones for ordinary enhancement levels, Breakthrough Stones for cap progression, scrolls for specified slots, socket stones for property changes and crystals for Arcana. Always verify the live client’s requirements, failure text, currency charge and recovery preview before spending.
