Aegaeon's Core Crystal

Aegaeon's Core Crystal is a unique Core Crystal in Xenoblade Chronicles 2. It is obtained following Emperor Niall's death and eventual resurrection on the Titan Battleship. Only Mòrag can resonate with Aegaeon's Core Crystal. Upon doing so she will re-awaken the Legendary Blade Aegaeon. Engaging in battle (the enemy does not need to be defeated) 22 times is needed in order for Aegaeon to be awakened.
