SetItemType

Defines which items can be set items and which set they belong to

This configuration file defines which items can be set (ancient) items and maps them to their corresponding set bonuses in SetItemOption.xml.

ItemOptionRate.xml	SetOptions section determines set tier on drop

How It Works

When a player equips items:

1. Server checks if item is a set item (bits 0-1 of m_SetOption must be 1 or 2)

2. Looks up item in SetItemType by Section/Type

3. Uses bits 0-1 to select OptionIndex: value 1 = OptionIndex1, value 2 = OptionIndex2

4. Counts matching set pieces across equipment for that OptionIndex

5. Applies bonuses from SetItemOption based on piece count

Structure

<SetItemTypeList>
    <Item Section="7" Type="1" StatType="3"
          OptionIndex1="11" OptionIndex2="12"/>
</SetItemTypeList>

Attributes

Attribute	Type	Description
Section	int	Item category (0-13, see table below)
Type	int	Item type index within category
StatType	int	Stat bonus type (see below)
OptionIndex1	int	First set ID reference (from SetItemOption.xml)
OptionIndex2	int	Second set ID reference (0 = none)

StatType Values

Value	Stat	Effect
0	None	No stat bonus from set tier
1	Strength	Adds STR based on stat tier
2	Dexterity	Adds AGI based on stat tier
3	Energy	Adds ENE based on stat tier

Stat Tier Multiplier: The item's SetOption byte contains stat tier info in bits 2-3. The bonus is calculated as ((m_SetOption >> 2) & 3) * 5. Valid stat tier values: 0 = +0 stat, 1 = +5 stat, 2 = +10 stat, 3 = +15 stat. This is independent of which set the item belongs to (bits 0-1).

Item Index Calculation

ItemIndex = Section * 512 + Type

Section	Category
0	Swords
1	Axes
2	Maces
3	Spears
4	Bows
5	Staffs
6	Shields
7	Helms
8	Armor
9	Pants/Gloves/Boots
10	Rings
11	Amulets
12	Wings
13	Misc

OptionIndex Reference

The OptionIndex values reference set definitions in SetItemOption.xml:

OptionIndex	Set Name	Typical Items
1	Warrior	Morning Star, Leather set, Ring of Ice
2	Anonymous	Buckler
3	Hyperion	Skull Staff
4	Mist	Bronze set
5	Eplete	Skull Shield, Bone set, Pendant of Ice
...	...	...

Dual Set Membership: Items with both OptionIndex1 and OptionIndex2 can contribute to TWO different sets simultaneously.

Examples

Armor Piece

<!-- Dragon Helm (Section 7, Type 1) belongs to Hyon set (11) and Vicious set (12) -->
<Item Section="7" Type="1" StatType="3" OptionIndex1="11" OptionIndex2="12"/>

• StatType=3: Gains +5 ENE per tier level

• Can contribute to either Hyon or Vicious set bonuses

Weapon

Accessory

Important Behavior

Duplicate Prevention: If two identical items are equipped in both weapon slots or both ring slots with the same OptionIndex, only one counts toward the set bonus.

SetOption Byte Structure: The SetOption byte encodes two pieces of information:

• Bits 0-1: Which set (1 = OptionIndex1, 2 = OptionIndex2). Must be 1 or 2 for valid set items.

• Bits 2-3: Stat bonus tier (0-3). Multiplied by 5 to get the bonus: 0=+0, 1=+5, 2=+10, 3=+15.

This is determined when the item drops based on ItemOptionRate.xml SetOptions section.

OptionIndex 0: Using OptionIndex=0 means "no set contribution" for that slot. Don't confuse with set ID 0 which doesn't exist.

Common Issues

Item Not Recognized as Set: Verify the item has SetOption set (from ItemOptionRate SetOptions). An item listed here but without SetOption on the actual item instance won't activate set bonuses.

Wrong Section/Type: Double-check your Section and Type values match Item.xml exactly. A mismatch means the item won't be found.
