Diablo II v1.09 Magic Properties

Diablo II Item Magical Properties

for Diablo II v1.09 and the Diablo II Expansion Set: Lord of Destruction

This page gives a detail of each magical property an item can have. See the Item Format page for a view of the complete item structure.

Following the item-specific data are a variable number of variable length bit fields describing any magical enhancements placed on the item. Each property begins with a 9-bit identifier. An identifier of 0x1ff (all 1's) indicates the end of the property list ... except in the event the item belongs to a set, in which case there will be another one or two groups of magical properties following. I have yet to determine how the length of the list is determined for set items.

To read a magical property, first look up its 9-bit ID in the first column. The second column shows you how many bits to read to get the value associated with that property (e.g., the amount of fire resistance). The bias field, if present, tells you the amount to subtract from that value to get the actual amount shown in the game; for example, if the field for Extra Gold from Monsters has a value of 150, and the bias is 100, your property is 50% Extra Gold. A few of the items require a little more math; these will be explained in the Contents column.

Several magical properties have two or more data fields. Read these in the order listed in the table. Each magical property ID is associated with a fixed number and size of data fields.

+X to Strength

+X to Energy

+X to Dexterity

+X to Vitality

+X to Life

+X to Mana

+X to Maximum Stamina

+X% Enhanced Defense

+X% Enhanced Damage

Note: In all of the items I've examined, the two data fields have the same value.

"Jesus on Bass" suggests that one data field enhances minimum damage while the other field enhances maximum damage. I have experimented and confirmed that the first field enhances your maximum damage, and the second field enhances the minimum damage.

Adds X-Y cold damage

This seems to be the duration of the cold/freeze effect. Divide the value by 25 to get the number of seconds.

Adds X-Y poison damage over Z seconds

This property is a tricky one to figure out. For the mathematically inclined, the first two fields give the minimum and maximum, respectively, of ¹/₂₅₆^th of a unit of damage every ¹/₂₅^th of a second. The third field gives the duration of the poison; you divide by 25 to get the number of seconds. Therefore, to compute the amount of damage shown in the game, multiply the first field by the third and divide by 256. (Repeat with the second field.)

For example, if the field values are 30, 60, and 75, you get 30*75/256=8, 60*75/256=17, and 75/25=3, so the displayed property is "Adds 8-17 Poison Damage over 3 seconds".

+Y to spell X (character class Only)
This property is usually applied to class-specific items found in the Expansion Set. The first value selects the skill; there are too many to list here, but I may provide them on another table if people ask nicely. The second value determines how many additional skill points are given.
Note that these three properties are all the same. I presume different ID's are used because you can have up to three of these (ten in an Expansion Set game), but no two properties for an item may have the same ID.

+X% Damage to Undead
Note that many types of weapon have a certain amount of this property inherent in the weapon class, usually with values of 50% or 150%. This property is added on top of the weapon's base Damage to Undead. For example, a flail may have a base rating of 50% Damage to Undead. If this magic property is added to it with a value of 121, then the displayed value is 121-20+50=151%.

Adds X extra sockets to the item.
This is simply added to the item's natural number of sockets. It has no effect if the item is not already socketed. This property may allow an item to have more sockets than the maximum normally permitted on the item.
Warning: If you give an item too many sockets, you run the risk of being unable to load the character with strange errors! And even if the game does load successfully, it could crash when you add too many gems to the item!

This property is usually applied to rings or amulets.

Repairs 1 durability in X seconds
The value of the data field is not actually a time period, but a frequency in terms of the number of times durability is repaired over a period of 100 seconds. For example, if the value is 5, then this property repairs 1 durability in 100/5=20 seconds.

253

Replenishes Quantity
As in the previous property, the value of the data field is a frequency in terms of the number of items replenished over a period of 100 seconds. For example, if the value is 4, then this property replenishes 1 item in 100/4=25 seconds.

254

Increased Stack Size
The value is the number of additional items that can be placed on the stack (beyond the base limit).

Note:

This range of magic properties change value depending on the time of day in the game. The format of the bit fields is the same in all cases. The first 2-bit field specifies the time of day when the value is at its maximum:

0	During Daytime		1	Near Dusk
2	During Nighttime		3	Near Dawn

The second and third fields are, respectively, the minimum and maximum values of the property. It has the maximum value at the time specified, the minimum value at the opposite time, and a value halfway between minimum and maximum during the in-between times.
A huge thanks goes to Gollen of Hungary for providing a table that revealed these and many other codes in this table.
