I couldn't miss the chance to practice my drawing!
The Green Ahriman is an enemy from Final Fantasy Crystal Chronicles: Echoes of Time. They are not very difficult enemies to fight, though they tend to knock the player back often if they get in close to physically attack them. Using Gravity works well on them, leaving them wide open to being attacked by the player. Else, if the player does not wish to get in close to fight them, they may opt to fight at long distance using a ranged weapon.
