Team Fortress 2 Item Attribute Indexes

This is a list of the item attribute indexes in TF2. These are useful for applying to weapons to change how they work.

This was created as a companion list for the Item Definition Indexes list, which contains the indexes of the weapons themselves.

This list is divided into Attribute Types, Positive Attributes, Negative Attributes, and Neutral Attributes.

Normally, you'll want to use this with TF2Items.

Attributes that have no weapons listed may not work. Matched attributes where the opposite

Attribute Types

Type	Description	Example
percentage	Expressed as a decimal. 100% is 1.0, 90% is 0.9. Sometimes boolean attributes are represented as percentages.	Natascha: "damage penalty" "0.75" does 75% of normal damage.
inverted percentage	Expressed as a decimal. Value is a percentage, but the percentage is subtracted from 100% when displayed to the user.	Übersaw: "fire rate penalty" "1.2" sets the fire rate to 80% but displays that the weapon fires 20% slower.
additive	Value is added to the default value. Value can be positive or negative. Boolean values are normally expressed as additive.	Blutsauger: "heal on hit for rapidfire" "3.0" makes a Medic heal 3hp whenever damage is dealt with it.
additive percentage	Value is a percentage added to the default value. Value can be positive or negative.	Übersaw: "add user charge on hit" "0.25" makes a Medic gain 25% uber whenever he hit someone with it.
or	Used on only one attribute (see example) for a boolean value. Usually, additive is used instead.	Axtinguisher: "crit vs burning players" "1.0"
