Jansen Friedh is a male magician who serves as a large portion of the comic relief in the game, he is one of the five mortal characters from the game and is the first mortal character to join your team. Physically weak and cowardly by nature, Jansen prefers to let his magic do the talking during a battle. He is especially skilled in the use of black magic, using it to rain destruction down on his enemies... from a safe distance of course. Due to his sarcastic and clownish nature, he is very popular among fans of the game. However, it is clear that beneath the exterior he shows, he is a very kindhearted and caring person, for example; when he saves a bird's life on the White Boa after being captured, and the emotion he shows during Lirum's death scenes.
Jansen is a terrible physical attacker, and his low magical and physical defense stats combined with his low HP make him a poor defender as well. Therefore, for as long as he is a party member, he should be kept in the back row. Physical attacks made by Jansen might seem pointless, but after acquriring or assemblying rings, he can be equipped with ailment-inflicting rings and launch regular attacks on turns when magic is unnecessary or impractical. That way, other characters can use a Bruiser Ring or something similar to maximize damage output.
He is most competent as a magical attacker, and his healing and buffing power is good at first but only because he is the only character capable of providing these assets. After Ming joins the party, bringing the total to six when only five can actively participate, Jansen's spot in the party becomes threatened and is decided by the player's preference. He will most likely be competing with Mack and Cooke for the spot since the player will most likely not want to sacrifice Kaim's attacker-defender role or Seth's balance. By removing Jansen from the party, all magical offense is sacrificed unless Ming learns his black magic first. By leaving him in the party and also having Ming learn his black magic, the party's magical offense is more than doubled.
