As you likely well know by now, Phantoma is obtained from most enemies after they are defeated. This section of the guide will focus on more of the specific details of Phantoma: their drop rates, who drops them, and where you can buy them.
Specific Phantoma rarely appear from any specific enemies. Instead, the Phantoma you receive from a defeated enemy will vary depending on which character you use, what weapon, what skills or magic, or whether the enemy is associated with a specific element.
