📑ItemOption

Special bonus definitions for wings, rings, pendants, and mounts (the type of bonus that scales with the item's enhancement level, such as Fenrir, Dark Horse, and elemental rings).

Column	Accepted values	Description
IND (Index)	Number from 0 to 13	Not the item code. This is the item's special bonus slot. An item can have multiple special bonuses at the same time, each assigned to a different slot.
OPI (Option Index)	Number (fixed bonus ID)	The bonus granted by this slot. This is a fixed server-defined bonus ID (e.g. increased movement speed, wing HP bonus, critical damage rate). New bonus types cannot be created by editing this file.
OPV (Option Value)	Number	Strength/value of the bonus.
MNI / MXI (Item Min/Max Index)	Number (item code range), or *	Item code range this rule applies to. * = no limit on that side of the range.
MNL / MXL (Item Min/Max Level)	Number, or *	Item enhancement level (+0, +1, etc.) this rule applies to. * = no limit on that side of the range.
ISK (Item Skill Option)	Number, or *	Requires the item's Skill option to be at least this value. * = no requirement.
ILK (Item Luck Option)	Number, or *	Requires the item's Luck option to be at least this value. * = no requirement.
ILO (Item Life Option)	Number, or *	Requires the item's Additional Option (Life/Option) to be at least this value. * = no requirement.
IEX (Item Excellent Option)	Number, or *	Requires the item to have at least one of the Excellent option bits specified by this value (bitmask, using the same format as ExcellentOptionRate.txt). * = no requirement.
IAP (Item Ancient Option)	Number, or *	Requires the item to have the specified Ancient/Set option bit(s). * = no requirement.
Comment	Text after //	Free comment (typically the item name), ignored by the game.

Notes

• IND is the easiest field to confuse: although it looks like an item index, it actually represents the special bonus slot. The same item may have multiple entries with different IND values—for example, a wing can receive one bonus in slot 1 and another in slot 2 at the same time.

• MNI/MXI (item code range) together with MNL/MXL (item level range) determine exactly which item instances receive the bonus. This is how, for example, a +9 wing can gain a bonus that the same wing at +0 does not.

• ISK, ILK, and ILO are minimum value requirements: the item must already have those options at or above the specified values. IEX and IAP, on the other hand, are bitmask requirements: the item must have at least one of the option bits specified by the value, rather than meeting a minimum numeric value.

• The bonus ID (OPI) comes from a large, fixed server-defined list (covering dozens of effects, from increased movement speed to critical damage resistance). It is not possible to create new bonus types simply by editing this file.
