Force Enchanter

The Force Blader's first Battle Mode cancels and doesn't allow you to cast your buffs (but you can still be buffed by other players) and doesn't allow you to cast Magic Attack Skills. In return, each of your Magic Spells will add a considerable buff to the Battle Mode : Earth Spells (Terra Arrow, Stone Cannon etc.) increase Defense, Wind Spells increase Attack/Defense Rate, Water Spells increase your MAX HP/MP, and Fire/Ice/Lightning Spells increase your Attack (beware : only one of these three elements is counted each time, and not all three of them togheter. This means only the strongest between the three of them is counted). Rumors tell that Lightning Spells add the greatest Attack buff between the three of these elements, so give it a shot. Upon transformation, all your learned Magic Skills are counted, and their buffs are applied to the Battle Mode.
Obviously, the higher the Grade and the Level a Magic Skill is, the greater the buff it applies to the Battle Mode is. This means, for instance, that Terra Lance adds much more Defense than Terra Arrow, a Lv15 Lightning Cannon increases further your Attack value than a Lv4 one and so on. Only the highest Grade Magic Spell of each element is counted toward Force Enchanter's buffs. So, if you learned both Wind Blast and Wind Lance, only Wind Lance will be counted toward Force Enchanter Mode's Attack/Defense Rate buff.
This Battle Mode can make all your stats quite high, and may be preferable opposed to Blade Shooter, since it doesn't allow you to use some Attack Skills such as Infernal Stigma or Abyssal Crystal.
