Beesly's Upgrade from Netherite

The Tarnex mod adds a new material called Tarnex, which is one tier above Netherite in terms of strength and durability. Tarnex is found in the Nether and can be used to craft tools, weapons, and armor that outperform Netherite equipment. Items made from Tarnex have higher durability, deal more damage, and mine blocks slightly faster than their Netherite counterparts. The mod is designed to extend progression for players who have already reached the endgame, providing a clear upgrade path without changing core mechanics.
