Unnamed Core Crystal

The Unnamed Core Crystal is a unique Core Crystal in Xenoblade Chronicles 2. It is given to Rex by Gramps during Chapter 2. It is used as part of the tutorial for Blade Resonance. When Rex resonates with it, he will awaken always a Common Blade with the Knuckle Claws weapon type and Wind Element, however the gender, name, and Affinity Chart of the Blade will be random. The Common Blade obtained from this Core Crystal cannot be released or transferred to another Driver through the use of an Overdrive Protocol.

Upon entering New Game Plus, Rex will lose the Common Blade obtained from this Core Crystal. Once Gramps gives Rex the Unnamed Core Crystal again, Rex will awaken the same Common Blade he did before. This Blade will have the same name and gender, and will also retain all progress on their Affinity Chart and current Core Chip.
