Resistance Formulation
The author built this one for Minecraft 1.20.1 on Forge. On other versions it may install and then do nothing.
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 variablelevel(default"0.20 * level")flatReductionPerLevel→ additional flat % per level (default0.00)maxReduction→ caps damage reduction (default0.00)
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
