The Starcilium Mod (Forge) 1.15+

This mod is very simple and adds one new ore to the game, called " Starcilium".  

Starcilium is stronger than diamond and it has the ability of high enchantability and durability AND it spawns very rarely in the nether.

Starcilium allows for complete blast protection decoration blocks and a fancy new armor set along with new tools.

This mod also adds a new apple which is an upgrade of the golden apple, which you use to craft an Enchanted Golden Apple.

The metal is very strong and has twice the durability of diamond tools.

Some lore behind this specific metal and why the ancients used it:

Starcilium or also known as 'Celestial Tungsten" is a very hard metal capable of conductivity and energy manipulation. It takes a lot of heat to forge and form this metal into a more malleable state. It is formed in the deepest parts of the nether said to be once apart of the void itself. The magical properties of this metal allow for the completion of the legendary "Notch Apple" used in the most precarious of situations.

Enjoy for now!
