Item Modifiers
by alfuwu
Item Modifiers gives weapons and tools random prefixes such as extra damage, critical strike chance or knockback, modeled on the modifier system in Terraria.
What it does
Each weapon or tool has a default 25% chance of receiving a modifier when it is created. A modifier either raises or lowers one or more stats, for example adding 1 damage with 3% more critical strike chance and 10% more knockback, or removing damage and knockback together. The set of modifiers applies to the universal weapon category, so swords, axes and similar items all qualify. The chance and the list of modifiers can be changed in the mod's config file.
The mod requires Cloth Config API for its settings screen and Fabric API for hooks into the game. Item Modifiers runs on the server, and clients may install it but do not need to. Files are published for Fabric and Quilt across 15 release versions, with 3-1.20.x for 1.20.4 as the latest file. The code is released under the MIT License and is open source, and the repository and issue tracker are public.
Key features
Terraria-style modifiers
Weapons and tools can receive prefixes that change damage, critical strike chance or knockback, following the Terraria approach.
Positive and negative rolls
Some modifiers raise a stat while others lower damage or knockback, so an item can end up stronger or weaker than its base form.
Configurable drop chance
The default 25% chance applied to every item can be adjusted in the config, along with the set of modifiers that may be rolled.
Universal weapon coverage
The modifiers apply across the universal weapon category, so the system is not limited to one item type.
