AION 2 Gear Enhancement and Manastones

Quick answer: Equipment enhancement in AION 2 is guaranteed up to +10 and can fail from +11 upward, but a failure never destroys the item or drops its level — you lose only the materials. Eight different enhancement materials exist and they are easy to mix up. Manastones and theostones are socketed separately from the level itself, and they are the cheapest way to add stats to a fresh piece of gear.

The failure rule, stated precisely

This is the single most important thing to know before you spend anything, because the widely-repeated claim that a failed enhancement destroys your item is wrong for AION 2. That claim comes from a 2009 discussion about the original AION.

What actually happens on a failure in AION 2:

The item is not destroyed. It stays in your inventory exactly as it was.
The enhancement level does not drop. A +12 item stays +12 after a failed attempt.
The materials are consumed — the Enhancement Stones and the Kina you put into that attempt.
Your success chance goes up. Each new attempt is more likely to succeed than the one before it.

That last point is what makes high enhancement levels feel different from most MMORPGs: failure is a tax, not a catastrophe. The risk in AION 2 is not losing an item, it is spending Kina on something you will replace in a week.

The chance increase is reported by one community source as roughly +5% per failed attempt. Treat that as a community figure rather than a confirmed mechanic — the official wording only says the chance rises gradually, and NCSOFT has not published the exact value.

The eight enhancement materials

The real source of confusion in gear enhancement is not the mechanics, it is the names. Eight materials, similar names, and different sources translate them differently.

Material	What it does	Where it comes from
Enhancement Stone	Basic enchanting of weapons, armour and accessories	Quests, daily dungeons, hideouts, gear extraction
Breakthrough Stone	Breaking through the regular enchantment cap	Quests, daily dungeons, subjugation battles
Draconic Essence / Radiant Draconic Essence	Highest pendant levels	Expedition and Sanctuary dungeons
Enhance Scroll (amulet, belt)	Required extra item for two slots	Strongholds, Abyss shop
Manastone	Sockets into weapons and armour, adds stats	Crafting and loot
Spirit Stone	The same, but for accessories	Crafting and loot
Mysterious Crystal	Refining Arcana	Arcana extraction, seasonal shop and missions
Pure Crystal (soul-bound)	Locks one Arcana property	In-game rewards, cannot be traded

There is a rule that makes this list easier to hold in your head: the first four items upgrade the item as a whole, while the other four add or change its properties. If you are unsure what you are holding, ask whether it raises the item's number or gives it an ability.

Enhancement caps by item grade

How far a piece can be pushed depends on its grade. Both the enhancement ranges and the breakthrough steps live in the Integrated Enhancement menu, which also handles manastone and godstone imprinting.

Grade	Enhancement range	Beyond that
Unique	+0 to +15	Five breakthrough tiers on top
Hero	+0 to +20	Five breakthrough stages of its own

Unique weapons have four manastone slots and one godstone slot. Every enhancement and breakthrough step raises the item's stats, so both feed directly into Combat Power.

A piece of armour that has been enhanced receives more than raw numbers. Since 31 December 2025, armour and accessories gain twice the Defence and HP they used to from every enhancement and breakthrough step, and since 22 April 2026 each armour breakthrough stage also adds 1% to the HP increase stat.

⚠️ These figures come from the Korean and Taiwanese service, which has been live since 19 November 2025. As of 2 October 2026 NCSOFT has not published which systems, or which level cap, the global service opened with when Advance Access began on 30 September 2026.

Hero-grade success rates after the February 2026 patch

The patch of 11 February 2026 reworked the top of the Hero-grade curve, lowering the Kina and Enhancement Stone cost of every attempt from +15 upward. Players who had already enhanced past +15 were refunded the cost difference based on their play logs.

Step	Chance before 11 Feb 2026	Chance after
+15 to +16	20%	65%
+16 to +17	15%	50%
+17 to +18	15%	35%
+18 to +19	10%	25%
+19 to +20	10%	20%

So the base numbers from the developer stream of 1 October 2025 — a guaranteed +10 — still hold, and everything above it got substantially more reliable in February.

Breakthrough costs in Kina

Breakthrough is charged in Kina rather than in stones, and the same February 2026 patch cut the price of every Hero-grade stage and refunded earlier spending.

Hero breakthrough stage	Kina before	Kina after
1	1,000,000	600,000
2	1,500,000	900,000
3	2,400,000	1,400,000
4	4,100,000	2,000,000
5	7,300,000	3,000,000

Advancing a Unique piece to its Hero-grade counterpart is part of a process called Advanced Succession, and it keeps your progress: because Hero gear has five more enhancement levels, the breakthrough tiers of the Unique piece become enhancement levels on the Hero piece.

Unique piece	Hero result
+1 to +15	Same enhancement level
Breakthrough tier 1	+16
Breakthrough tier 2	+17
Breakthrough tier 3	+18
Breakthrough tier 4	+19
Breakthrough tier 5	+20

NCSOFT added that mapping to the in-game help on 10 June 2026.

Manastones, spirit stones and theostones

Manastones are socketable items that go into compatible weapons and armour to provide additional stat bonuses. Their effects and values are determined randomly, so slotting a manastone with the stat you want is the actual skill — not the socket itself. Soulstones do the same job for accessories, and better stones have higher chances of granting unique stats.

Theostones are socketed onto weapons and guards, and they add effects to your attacks rather than plain stats. They come from Regional Quests, Hidden Cubes, Transcendence Dungeons and the Abyssal Shop, with some sources providing Rare or Epic grades. Engraving a theostone through the Enhancement Hub costs 10,000 Kina, and removing an equipped theostone makes it vanish permanently — the one genuinely destructive action in this whole system.

Theostone effects and their chances are still unconfirmed in the global client.

Choosing which stat to socket

Different roles want different numbers, and putting the wrong stone on a piece you plan to keep is the expensive mistake.

Role	Primary socket stat	Secondary socket stat	PvP-specific stat
Tank / frontline	Physical Defence, Health	Parry / Block	PvP damage reduction
Melee DPS	Critical hit, Attack accuracy	Evasion	PvP attack power
Ranged magic DPS	Magic boost, Magic crit	Magic accuracy	PvP attack power
Healer / support	Cast speed, Health	Magic resist	PvP damage reduction

A physical damage dealer gains almost nothing from magic amplification, and a support character usually wants health pool expansion and casting speed above everything else.

Soul binding and gear transfer

Soul Binding re-rolls the specific stats of your equipment, with three functions. Reset re-rolls all of an item's stats. Sync re-rolls a stat, and requires you to have two of the same piece. Bind raises an item's stats to their full potential.

Gear Transfer moves a piece's Enhancement, Amplification and Soul Binding stats to another piece. A Superior Gear Transfer additionally carries gear from Unique grade up to Hero grade along with those stats: Unique gear with enhancement levels 1–15 transfers to Epic gear at the same enhancement level, and higher Enhancement and Amplification levels transfer to progressively higher Hero levels, with Amplification levels 1–5 mapping to Hero enhancement levels 16–20.

The number of successful Seasonal Gear Transfers is unlimited during a season and resets when the next season begins, so your gear progression can be moved repeatedly within a season without limit.

What extraction refunds, and what it does not

Breaking a piece down is a normal, recommended step in AION 2, not a risk. It is how you get your Enhancement Stones back.

What you put in	Refunded on extraction?
Enhancement Stones	Yes, all of them, regardless of the level reached
Kina	No — spent currency is gone
Manastones	No
Theostones	No

The practical consequence is that Kina is the real cost of enhancement, not the stones. Budget for it.

Where to spend early, and where not to

In the levels 25–40 band the game hands out enough Enhance Stone that a fully cleared set of hideouts is enough material to take multiple gear pieces several enchant levels higher. Per first clear, a level 30 hideout gives 1,500 Enhance Stones and levels 35 and 40 give 1,750–2,000, each alongside 15,000 Kina, 2 Daevanion Crystals, a wing or statue material and a title. These are one-time clears, so clear every one you can find.

Three rules cover most cases:

Put early upgrade resources into your main weapon first. Weapon enhancement improves your damage, and everything else follows.
Upgrade several items to +1 rather than pushing one item to +5. Spreading low levels across pieces beats a single deep enchant while you are still replacing gear.
Do not enhance early-game gear past a safe minimum. Save your highest-grade stones for endgame sets. The item will be replaced anyway.

The Enhancement Hub is opened with the "Enhance all" option, and it also shows gear stored in your inventory — not just what you are wearing. You do not need to swap pieces back and forth to work on them.
