Crystal Armor

Crystal Armor is an Armor set crafted with Crystal Fragments. This armor set is not part of a collection and has no unlock requirements.

This set is typically reforged to Wise or Necrotic for increased and is often used for the 7th step of the Romero and Juliette quest, or for dragons.

It is possible to dye Armor that is a custom color by going into the light level which gives you the color you want and double-clicking the piece you want to dye twice on the Armor. This will dye the Armor that color.

The ability which doubles the armor stats also applies to reforges put on the set and hot potato books.

Acquiring
Crystal fragments can be obtained as a rare drop from Zealots (the ones holding Ender Chests), as a drop from any Dragon fight if the player breaks End Crystals that heal the Ender Dragon during a Dragon Fight (1 Crystal Fragment for every End Crystal broken during the fight) or from getting a high ranking in an Endstone Protector miniboss. Dragon fights are the most efficient way of getting a larger amount at once.
