Emily is the female swordmaster option in end.earth, whose attribute is fire. This means she works well with Karina and Bruce- but is it a good idea to have an all-physical team?Emily specializes in what John does not: Defense. In fact, she has the highest defense stat in the game. Emily's resistance is better than John's, too. However, she doesn't have nearly as much strength or endurance.
Whenever including a character on your team, you should find the situation that they best excel in, and maximize their potential. In Emily's case, she takes little to no damage from attacks with her high defense stat. Giving her very well-upgraded armor can make her seem nearly indestructible. However, be aware that impenetrable defenses are no match for high-priority attacks.
