Model

EzStatus

Status

A status is an entity that exists for each property ID and holds the value of the current grade.

The property ID is a status-specific ID and can be set to any value by the developer. It is strongly recommended that the value be the same as the property ID of the GS2-Experience.

TypeConditionRequiredDefaultValue LimitsDescription
gradeNamestring
~ 128 charsGrade Model Name
The name of the grade model that this status belongs to. References the grade model definition which contains the grade entry mappings, linked experience model, and reward addition tables.
propertyIdstring
~ 1024 charsProperty ID
A developer-defined identifier for this grade status, unique within the user and grade model. It is strongly recommended to use the same value as the property ID of the linked GS2-Experience status, as this ensures correct synchronization of grade values with rank caps.
gradeValuelong11 ~ 9223372036854775805Current Grade
The current grade value of this status. Used as an index into the grade model’s grade entries array to determine the rank cap for the linked GS2-Experience model. When this value changes, the rank cap of the associated experience status is automatically updated to the value defined in the corresponding grade entry.

EzGradeModel

Grade Model

A Grade Model is an entity that indicates the rank of characters and equipment, and allows you to set the rank cap for GS2-Experience based on the grade.

TypeConditionRequiredDefaultValue LimitsDescription
namestring
~ 128 charsGrade Model name
Grade Model-specific name. Specified using alphanumeric characters, hyphens (-), underscores (_), and periods (.).
metadatastring~ 2048 charsMetadata
Arbitrary values can be set in the metadata.
Since they do not affect GS2’s behavior, they can be used to store information used in the game.
experienceModelIdstring
~ 1024 charsGS2-Experience Experience Model GRN
The GRN of the GS2-Experience experience model to link with this grade model. When a grade value changes, the corresponding rank cap in the linked experience model is automatically updated based on the grade entry mappings. This enables grade-driven progression where higher grades unlock higher rank caps.
gradeEntriesList<EzGradeEntryModel>
1 ~ 100 itemsList of Grade Entry Models
The ordered list of grade entries that map each grade value to a rank cap for the linked GS2-Experience model. The index in the array corresponds to the grade value, so the first entry (index 0) defines the rank cap for grade 0, the second for grade 1, and so on.
acquireActionRatesList<EzAcquireActionRate>0 ~ 100 itemsList of Reward Addition Tables
A collection of named multiplier tables used to scale reward amounts based on grade. Multiple tables can be defined to apply different scaling rules to different types of rewards (e.g., experience points, currency, items).

EzGradeEntryModel

Grade Entry Model

Defines the mapping between a grade value and a rank cap for the linked GS2-Experience model. Each entry also specifies regex patterns for matching property IDs, enabling the system to determine which resources can be used for grade-up operations and how their property IDs are transformed.

TypeConditionRequiredDefaultValue LimitsDescription

rankCapValuelong
0 ~ 9223372036854775805Rank Cap Value
The rank cap value to set in the linked GS2-Experience model when this grade is applied. When a player’s grade changes to the value corresponding to this entry, the rank cap of the associated experience status is automatically updated to this value, controlling the maximum achievable rank.

Methods

getGradeModel

Get a specific limit break / ascension model by name

Retrieves a single grade model by specifying its name. The returned information includes the grade entries (which define how the max level increases at each grade), the default starting grade, and the reward multiplier rates. Use this to display the details of a specific limit break system — for example, showing “Iron Sword: Grade 2 → Max Lv 70, Grade 3 → Max Lv 80” or “Current reward bonus: x1.5”.

listGradeModels

Get a list of limit break / ascension models

Retrieves all grade models registered in this namespace. A grade model defines a “limit break” or “ascension” system — it controls how much the max level (rank cap) of an item or character increases as the player raises its grade. For example, a weapon at Grade 0 might have a max level of 50, but after limit breaking to Grade 1, the max level increases to 60, Grade 2 to 70, and so on. The model also defines reward multiplier rates, which can increase the amount of rewards based on grade level (e.g., a Grade 3 character earns 1.5x gold). Use this to build limit break or ascension UI — for example, showing “Grade 2/5 — Max Lv: 70 — Next: requires 3 copies”.

applyRankCap

Sync the max level with the current limit break grade

Updates the max level (rank cap) in GS2-Experience to match the current grade (limit break level). For example, if a character was limit broken from Grade 2 (max Lv 70) to Grade 3 (max Lv 80), calling this ensures the Experience system knows the new max level is 80. This is useful when the grade was changed externally and the max level in Experience needs to be synchronized. Normally, the max level is updated automatically when grade changes, but you can call this manually if the data gets out of sync.

getStatus

Get the limit break / ascension status of a specific item or character

Retrieves the current grade (limit break level) for a specific property owned by the player. The property is identified by the grade model name (which limit break system to use) and the property ID (which specific item or character). Use this to display a limit break detail screen — for example, “Iron Sword — Grade: ★3 — Max Lv: 80 — Next limit break requires 2 more copies”.

propertyIdstring
~ 1024 charsProperty ID
A developer-defined identifier for this grade status, unique within the user and grade model. It is strongly recommended to use the same value as the property ID of the linked GS2-Experience status, as this ensures correct synchronization of grade values with rank caps.

listStatuses

Get a list of the player’s limit break / ascension statuses

Retrieves the player’s current grade (limit break level) for their items or characters. You can optionally filter by grade model name — if omitted, all grade statuses across all grade types are returned. Each status includes the current grade value and which property (item or character) it belongs to. Use this to build a list showing all limit-broken items — for example, “Iron Sword ★3, Fire Staff ★1, Dragon Armor ★5”.
