Onyx Ore is the next to final ore tier in SimpleOres. Unlike the other 5 ores, which all spawn on the Overworld, Onyx Ore spawns only in the nether, where it blends in with all the other Netherbrick blocks. Items crafted from Onyx have a very high number of uses.
The primary use of Onyx Ore is to drop the Onyx Gem, which is dropped when the block is broken, or obtained from smelting the ore in a Furnace, as shown below. The Onyx Gem can then be used for a large number of things, such as Onyx Tools, Onyx Armor, Onyx Bow and the Onyx Furnace, etc.
Onyx Ore spawns only in the Nether, where it can spawn at any height, with 5 blocks spawning in each chunk, in a vein of up to 8 (though it will never reach this due to there being a lower number of blocks per chunk). Due to its texture, Onyx Ore blends in with its surroundings, meaning it can be difficult to spot from a distance. The Onyx Ore spawn rate, spawn height and vein size can all be changed using the Config.
