Rarer Heavy Core

Heavy Core Drop Rate Changes

Vanilla (Default):

Heavy Cores have a 7.5% drop chance from an Ominous Vault.

On average, that means you'll get one about every 13–14 vaults.

With My Datapack:

Heavy Cores now have a 4% drop chance.

On average, you'll get one about every 25 vaults.

This makes Heavy Cores significantly rarer and more valuable compared to vanilla.
