Effective Armor Formula
Java mod listed for Minecraft 1.20–1.21. Downloads from the MC Java Mods app on Android.
⬇ Download on ModrinthThis mod replaces Minecraft's default armor calculation with the popular "Effective Health" formula, similar to the one used in games like League of Legends. Instead of offering diminishing returns, every point of armor now consistently adds 1% to your effective HP against physical damage. This makes armor values more intuitive and easier to balance.
The mod is designed for maximum compatibility and works seamlessly with other mods that add armor penetration or shred attributes.
