New endgame armour set

Thystalium(This is made up) is known to be the sharpest material of all dimension. It is a fusion of Amethyst, Echo shards, and crystal fragments.

Crystal fragments are a new item which can be found like ancient debris, but in the end. Each large end island will have a random chance to generate a crystal fragment which will be buried somewhere in the island.

Thytalium gear set is almost like nephrite where you need an upgrade template to change a diamond gear set to a Thytsalium gear set.

Thystalium Armour:
Each piece has thorns and when combined gives thorns 3 damage.
(Can be modified) If each piece of armour is enchanted with thorns 3, the armour+the enchant will combine it to be thorns 4. 
How netherite can be un burnable, the Thystalium gear set will not lose durability to thorns.

Thystalium Tools:
Since Thystalium is the sharpest material to exist, each tool will have +2 damage(can be modified)

In conclusion, the armour set has improvements but the idea gives a creative concept for a new balanced gear set that matches nephrite.
