Cordelica

'Note: Bringing a squad with only one element is highly discouraged in Cordelica. There are often Zone Monsters with opposite element with the other. Furthermore, in areas that have more than one boss, at least one of the bosses' elements might be strong against your units and may defeat all your units instantly by casting AoE.'
