Attribute Modifier
by Levviata
Attribute Modifier lets a player change the attribute values of items, such as weapon damage, armor and speed, from a Forge configuration file.
What it does
The mod changes attribute values on items and on living entities. Attributes covered include weapon damage, attack speed, armor, health caps, pursuit distance, resistance to being pushed back, and both ground and flying speed. Entries are added in a configuration file, so a server owner can set values without writing code. The author notes a fixed flying speed setting.
The mod requires Mixin Booter, which must be installed alongside it on the Forge loader. Attribute Modifier is published for Forge only, in a single game version, 1.12.2, with 1.1.1 as the latest file released on 2026-09-09. The server and every player need the mod installed. The license is a custom license, and the source code is not open source.
