Cor and alchemy

Seven Cor and Dragon Alchemy

The first selected Cor is available via an introductory letter from level 90 once per account. Then collect the fragments and contact the Alchemist: 10 fragments are exchanged for the selected Cor. Seven types of stones are supported and improvement through the standard alchemy interface. Cor are not added as a direct drop from each boss: the main way to obtain them is through shards and exchange.
