Modifier

Not to be confused with Stats.

Generally Modifiers change various aspects of the entity they are affecting. Most commonly Modifiers apply Stats, however they can also apply Buffs or grant Skills and can often be found on Items, Monsters, Strongboxess or Areas.

Overview

A Modifier should be seen as a instance of change applied to an entity. A basic modifier does nothing on it's own, it's given the effect by the associated Stats (and their values)), Buffs and Skills.

A modifier can be fixed (such as certain implicit modifiers on Items), but it can also be dynamically generated, usually as Affix or though Corruption.

Effects

For Stats modifiers include a minimum and maximum value, which is most commonly found on Item Affixes - the actual value of the stat in the cases where minimum and maximum are not the same will be randomized within, so for example a Stat with a minimum value of 1 and a maximum value of 3, can either be 1, 2 or 3.

If a Buff is specified, Modifiers also include a value for the buff, but unlike for Stats it is not randomized and fixed.

If a Skill is specified, the specified skill (at the specified level) will be granted to the relevant entity. The skill does not include values as they're defined by the skill level directly. Often this is found on items, where they grant skills, such as Unique Item

Conditions

Modifiers usually include conditions which are used to determine how they appear.

Mod Domain

The mod generation determines what entity the mod applies to. The domains are primarily reverse engineered, as detailed information has been removed from the game files.

Id	Type	Description
1	Item	The mod is generated on Items (but not Jewels or Flasks)
2	Flask	The mod is generated on Flasks
3	Monster	The mod is generated on Monsters
4	Chest	The mod is generated on Chests (i.e. Strongboxes)
5	Area	The mod is generated on Areas
6	Unknown
7	Unknown
8	Unknown
9	Stance	The mod is generated as a Stance (appears to be animation related)
10	Master	The mod is generated by Masters though Master Crafting
11	Jewel	The mod is generated on Jewels

Mod Generation Type

The mod generation determines "how" the mod will be created on an item. The generation types are primarily reverse engineered, as detailed information has been removed from the game files.

Id	Type	Description
1	Prefix	The mod is generated as prefix, for example Item Prefix
2	Suffix	The mod is generated as suffix, for example Item Suffix
3	Unique	The mod is "unique" - it is given directly to the relevant entity and not generated normally. For example, the mods on unique items have this property.
4	Nemesis	The mod is a Nemesis mod
5	Corrupted	The mod is a Corrupted mod and is given to the item upon corruption
6	Bloodlines	The mod is a Bloodlines mod
7	Torment	The mod is a Torment mod
8	Tempest	The mod is a Tempest mod

Level

The required level of the relevant entity. For example, this can be the required Item Level or a Monster level.

However, there are cases where this is not respected though. In particular this is the case for any mods that are directly given to other entities, such as Implicit mods or Monsters with innate mods.

It also appears the mod level can be a factor in calculating the level requirement of Items, in particular this is the case for mods on unique items.

Tags

Some mods use the internal Tag system to determine on which entities they can appear and how likely they are to appear on entities. A mod can add tags to the entity it is modifying.

It primarily functions like this:

• find the Tags on the entity
• match the Tags against the mod's list of tags.
• for the found mods get the associated spawn weighting of the tag
• if the spawn weighting is zero, discard the mod, otherwise use it
• if multiple tags apply, the left-most tags are most important, where the right most tags are the least

So, for example:

• item A has the tags [str_armour]
• item B has the tags [dex_armour]
• the mod has the tags [str_armour, int_armour, default] with values [1000, 1000, 0]
• result A: Mod can spawn on the item A because it has the tag str_armour with a weighting of 1000
• result B: Mod can not spawn on item B because it defaults to 0 and no tags are found
