Resistance Formula

THIS MOD DOESN'T REQUIRE SINYTRA CONNECTOR, UNLIKE RESISTANCE BALANCER

Lightweight, server-side-only mod that lets you define a custom formula for the Resistance effect’s damage reduction.
Tweak Resistance to be weaker, stronger, or anything in between—without touching armor math or other mods.

Features

Replace vanilla’s fixed 20% per level with your formula.
Add an extra flat bonus per level (e.g., +5% per level).
Works serverside only (clients don’t need it installed).
Prevents Resistance V+ invincibility by enforcing a minimum final damage.
Compatible with armor, Protection enchants, attributes, and most combat mods.

Configuration
A config file is generated at config/resistanceformula-common.toml.

Keys:

formula → math expression, using a variable level (default "0.20 * level")
flatReductionPerLevel → additional flat % per level (default 0.00)
maxReduction → caps damage reduction (default 0.00)

Examples:

Weaker than vanilla: formula = "0.05 * level"
Stronger than vanilla: formula = "0.10 + 0.15 * level"
Curved scaling: formula = "0.10 * (level ^ 1.25)", flatReductionPerLevel = 0.02

How It Works

Captures raw incoming damage before vanilla mitigation.
Adjusts the final damage so the net reduction matches your formula.
Guarantees you still take damage even at very high Resistance levels.

Testing

Try Resistance II with /effect give @s minecraft:resistance 99999 1 true.

Vanilla: 40% reduction
Config formula = "0.05 * level" → 10% reduction
Config formula = "0.25 * level" → 50% reduction
