About this Mod
⛏️ ReducedOres – Mod
Too many ores cluttering your world?
ReducedOres is a lightweight and highly compatible mod that lowers ore generation to bring back balance, challenge, and meaning to mining.
🔻 What it does:
- 📉 Reduces ore spawn rates across all dimensions,
- 🔘 Shrinks ore vein size (blob size) to avoid massive ore clusters,
- ⚙️ Fully configurable via the mod’s config file — tweak rates and sizes,
- 🔄 Works seamlessly with vanilla and modded ores from dozens of mods.

💡 Perfect for players who want:
- A more survival-focused or hardcore mining experience,
- To reduce resource overflow in large or exploration-heavy modpacks,
- To make every ore vein feel rewarding, not redundant.
🧩 Compatible with:
Most worldgen mods (e.g. Terralith, BetterNether, Create, AllTheOres, etc.)
Does not override loot tables or structure data — stays focused and modular.
📦 Lightweight. Configurable. Focused.
Every ore should feel like a discovery — not a given.
