Nether Gold Ore

Nether gold ore is a variant of gold ore found only in the Nether.

Natural generation
Nether gold ore generates in the Nether in the form of mineral veins. Nether gold ore attempts to generate 10 times per chunk in veins of size 10, from altitudes 10 to 117, in all applicable biomes.

Breaking
Nether gold ore requires a pickaxe to be mined.

Block loot
Nether gold ore drops 2-6 gold nuggets when mined with any pickaxe. Fortune has a 33.3% chance to multiply the drops by 2, Fortune II has a 25% chance to multiply the drops by 2 or 3 and Fortune III has a 20% chance to multiply the drops by 2, 3, or 4 for a maximum possible drop of 24 golden nuggets.

Piglins
Piglins will become hostile towards players that mine the ore, regardless if the player is wearing gold armor. The same case applies if the player mines gold of any type, not just the ore.
