Azure Knight Edit
The Azure Knight is very effective in both PVE and PVP. They are very powerful when it comes to tanking and taking down their opponents very fast.
A lot of the AK's in Expedition have decided the best way to pvp is to set their strength as high as they can and have 150-200 heal points... This is very effective but also very risky, if you are a person that likes to level... May I suggest not using this build at higher levels.
Ask around for tips of different builds such as:
Dex: Only for Armor
Heal: lvl 20 (20), lvl 30 (30)
Glass Cannon/Heal Build/Hybrid
Try your best too be buffed up when you PK/PVP and sometimes use Attack Accel buff when fighting Monsters.
