Arua Rose Knight is a powerful Job in the game. With this character you can fight higher level mobs that will make you level up easily.
Knights are also good in terms of PVP, they have a hard body which means they have higher defense and life compare to other jobs.
A good Plan in Clan vs. Clan Fight is that you need to use your Knights as your defense character. Knights must be the front liner; the other Jobs are the supporting characters, as for the backup of the Knight.
Knights require strength, concentration and Sensibility.
