WHERE THE NUMBERS COME FROM

Where did that item stat come from?

When StatTuner shows a weapon attack value, armour bonus, resistance or Item Power number, that value should have a traceable origin. It may come from a public game dataset, an official guide, a game wiki, a structured export or a reliable community reference.

Sources are not all treated as equally reliable. A current value visible in the live game client carries more weight than an old forum post, and a documented mechanic carries more weight than an unexplained number copied between websites.

A source link does not mean that the source owner, game publisher, wiki or community endorses StatTuner. Sources are referenced so players can understand where the data came from and check it independently.

What We Look for First

When several sources mention the same item or mechanic, we try to use the most direct and current evidence available.

01 Live game values Current values visible in the relevant game client, supported by a clear screenshot or repeatable test.

02 Publisher information Patch notes, official guides, public databases, APIs and documentation released by the game operator.

03 Established reference sites Maintained game wikis and structured datasets with a visible update history and consistent item records.

04 Community testing Repeatable player tests, technical discussions and measurements used when the server formula is not public.

This order is a guideline rather than an automatic rule. A stale official page can be less useful than a current in-game value, and a community test can be more informative than a guide that does not explain its calculation.

Sources Used for Each Game

Each game has a different data ecosystem. StatTuner does not use one database or one calculation method for every game.

Metin2 Gameforge Wiki and item records

Metin2 equipment families, character classes, bonuses, elemental systems and general game terminology are checked against public Gameforge Wiki pages and available item catalogue records.

Weapons, armour and accessory families.
Displayed attack and defence values.
Class restrictions and equipment requirements.
Bonus and resistance terminology.
Publicly documented game mechanics.

Private server-side damage behaviour and undocumented coefficients are kept separate from directly recorded item stats and are labelled when an estimate is involved.

Knight Online Item catalogues, guides and forum references

Knight Online equipment records and inventory images are reviewed together with available NTTGame guides, forum references and public item catalogues.

Weapon attack and armour values.
Required class and attribute information.
Strength, dexterity, health and resistance bonuses.
Upgrade-level item records where available.
Public explanations of classes and combat systems.

Complete server-side damage resolution is not treated as public fact when the full calculation cannot be verified. In those cases, StatTuner uses a consistent comparison model and identifies the result as mixed, community-based or estimated.

Old School RuneScape OSRS Wiki and structured item exports

Old School RuneScape equipment bonuses and item records are supported by OSRSBox-compatible exports and OSRS Wiki reference pages.

Equipment attack and defence bonuses.
Strength and prayer bonuses.
Attack speed and combat style information.
Attack-roll and max-hit mechanics.
Monster defence and resistance information.

Special attacks, set effects, ammunition rules and conditional bonuses are included only when the selected calculation explicitly supports them.

Albion Online Albion data exports and public wiki references

Albion Online item records are supported by available Albion data exports and public Albion Online Wiki reference pages.

Equipment identities and tiers.
Item Power information.
Armour and weapon classifications.
Spell and ability descriptions.
Damage, defence and resistance context.

Enchantment, quality, mastery, specialization and conditional ability effects may require separate calculation support. A base item record alone does not automatically include every possible in-game modifier.

Item Data and Combat Formulas Are Not the Same Thing

A common source of confusion is assuming that a verified item record automatically makes the final damage result exact.

These are two different layers:

Layer 01 The recorded item values

This includes values such as weapon attack, armour, strength, accuracy, resistance, health, Item Power or another directly displayed stat.

These values can often be checked against the game client, public datasets or reference pages.

Layer 02 How the game uses those values

The final result may also depend on hidden coefficients, random rolls, rounding rules, target conditions, server-specific behaviour and effects that are not publicly documented.

That layer may be exact, source-backed, mixed, community-based or estimated depending on the game and selected calculation.

A verified weapon attack value can be exact while the final damage result remains an estimate. StatTuner keeps these confidence levels separate instead of giving the entire calculation one misleading label.

What Happens When Two Sources Disagree?

Conflicting data is common in long-running online games. An item may have different values on regional servers, private servers, older patches or archived wiki pages.

When sources disagree, we review:

Which game version and region the value belongs to.
When the source was last updated.
Whether the value can be confirmed in the live game.
Whether another maintained source reports the same number.
Whether the difference comes from an upgrade or enhancement level.
Whether the item name is shared by multiple versions.
Whether the source is showing a base value or a modified value.

We do not automatically replace an existing value because a single page or screenshot shows something different. The game version, server, enhancement level and date must also make sense.

How Source Confidence Is Shown

Exact

The supported value or formula can be applied directly from documented or clearly recorded data.

Source-backed

The result uses values or coefficients taken from an identifiable public reference.

Mixed

Part of the calculation is documented, while another part uses assumptions, simplification or inferred behaviour.

Community

The mechanic relies mainly on repeatable player testing, public technical discussion or community measurements.

Estimate

The model provides a stable comparison, but the complete private server formula is not publicly available.

Confidence labels describe the basis of the calculation. They do not guarantee that every temporary effect, hidden mechanic or future game patch has already been represented.

How Data Is Updated

StatTuner data may be updated when:

A game publisher releases patch notes or balance changes.
A maintained public dataset publishes new item records.
A wiki page is updated with clearer information.
A player reports a value that can be independently verified.
A broken image, duplicate item or incorrect classification is found.
A calculation model gains support for an additional effect.

Updates are not always immediate. Large item catalogues may contain thousands of records, and a patch can affect item values, formulas, requirements and descriptions at the same time.

Where possible, changes are reviewed before being applied so that one bad source does not replace a correct dataset.

What We Do Not Treat as Reliable on Its Own

The following may be useful clues, but they are not normally enough by themselves to establish an item value or formula:

An undated image with no visible game version.
A forum comment without a repeatable test.
A copied database with no source or update history.
A video showing a result without the full character setup.
A private-server value presented as an official-server value.
An AI-generated explanation without supporting game evidence.
A calculation result that cannot be reproduced.
A marketplace listing used as proof of an item stat.

These sources may still help identify an issue, but additional confirmation is usually needed before changing StatTuner data.

Player Reports and Corrections

Players often notice regional differences and recently changed item values before a public database is updated.

To report a possible data error, include:

The game name and server or region.
The exact item, skill or page concerned.
The value currently shown by StatTuner.
The value you believe is correct.
The enhancement, quality or upgrade level.
A current screenshot, patch note or reliable reference link.

A submitted report is reviewed before a change is made. Different game regions and old item versions may legitimately contain different values.
