Buckshot's RPG Combat Attributes
Buckshot's RPG Combat Attributes replaces the vanilla combat formulas with a standardized set of attributes for armor, toughness and damage on NeoForge 1.21.1.
What it does
The mod rewrites how damage is calculated in combat. Armor reduces damage through a diminishing returns formula, and armor toughness becomes a flat reduction that is applied at a configurable point in the equation. Twelve new attributes let modpack developers and players scale combat values, and the vanilla 1.5x critical multiplier and the sweeping attack rule are removed in favor of a True Zero baseline.
Four Anti-Armor attributes give attackers ways to counter heavy armor: Resistance Piercing and Toughness Piercing ignore a percentage of the target's raw stat, while Resistance Penetration and Toughness Penetration subtract flat amounts afterward. Both defensive stats are resolved the same way before the damage phase begins. The mod requires Client and server installation, and its files are published for NeoForge 1.21.1 only.
Key features
Diminishing armor formula
Damage reduction follows effective armor divided by effective armor plus a configurable constant.
Reworked armor toughness
The Durable attribute decides when toughness reduces incoming damage, either before or after the armor percentage.
Anti-Armor attributes
Four attributes let attackers pierce or penetrate armor and toughness, in percentage or flat amounts.
Twelve new attributes
Additional attributes are available for custom scaling by modpack developers and players.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Custom combat balance
Modpack developers can adjust armor, toughness and piercing values to shape how fights feel.
Armor-focused builds
Players who invest in armor can rely on the diminishing returns formula, which never reaches complete damage immunity.
Who it’s for: Modpack developers and server owners who want a standardized combat framework, and players who build around armor and piercing attributes.
How it compares
Armor New Attributes is an MIT License mod for NeoForge 1.21.1 that is also client and server, but it is not open source, unlike this mod. Eternal Ascension targets NeoForge 1.21.4 under All rights reserved, so it is not available for the same version. SOUL ASCENSION is open source under the Mozilla Public License 2.0 and covers 1.21.1 – 26.2.

I replaced the combat, physics, and magic calculations in Minecraft with a standardized mathematical framework. All calculations follow a strict order of operations where percentage modifiers are applied first, followed by flat modifiers. I introduced 12 new dynamic attributes to support custom scaling for modpack…
