Sword
The Swordsman has the best survivability of all classes, which makes him the natural tank class. His attack is rather strong, but it can only affect a single non-flying target in the front row, so he should not be solely relied upon for offense. The Swordsman's basic magic skill, Flame Sword, attacks one enemy for a greater amount of damage.

Spear

The Spearman can attack a single non-flying foe in the front row. If there is another foe in the same column directly behind the target, that foe also receives damage, although half of the original target. The Spearman's basic magic skill, Lightning Spear, attacks two foes in a line for greater damage and slows them. At higher upgrade level, Lightning Spear hits up to 3 targets in the column. Aside from the damage from Lightning Spear, it's greatest strength is that it actually removes action points from the receiving targets.
 

Axe

The slow-moving Viking can attack a single target in the front row. If that target has one or two neighbors in the same row, then those also take some damage. This character has many hit points but low defense, especially versus magic - but this weakness is made up via high magic defense gear tha
