After the Legend and Armored Princess, the third story is presented with Warriors of the North. While the game takes place in the world of Endoria and many islands around it, it focuses on Viking protagonist, Olaf, son of a viking king, whose lands lately came to be plagued by the undead scourge. That is only a tip of the iceberg, as this sudden appearance of the undead troops on viking islands is but a vanguard of things to come. As you fight your way through the undead ranks you will notice that other lands suffer much the same fate and many friendly troops have already fallen and lands have been devastated. You may be a viking prince with a low IQ and a lot of witty answers in your repertoire, but that alone will not win this war.
Luckily, gods have been kind on your and granted you the ability to see and use the power of Valkyries at your side. Their stunning look is not what is deadly, each of the five Valkyries will bestow upon you a special skill you can use in battle, as well as a special ability that can be requested outside of battle, but needs time to recharge. While talking to Valkyries will let you use their abilities outside of battles which will strengthen your army, their special attack skills are used as in previous games, which require your rage points to be spent. You gather your rage points as before, by fighting enemies, and the better combos your use and more enemies you destroy, the faster the rage bar fills. Remain idle and avoid combat for a while, and you will see your rage bar completely deplete over time. As is the case in previous title, during big boss battles you will not be able to use your special powers, neither your own special attacks, nor those bestowed upon you by Valkyries.
Character classes for selection are no longer warrior, paladin, and mage; instead a Viking, a skald, and a soothsayer. The skills and upgrade principles remain the same, however, based on your class you will receive different amount on red, green and blue orbs that are used to upgrade your skills. You can upgrade skills from any class, but you may find yourself in lack of necessary orbs to unlock those skills. Aside from leveling up, upgrade orbs can also be found on the maps, earned by completing quests or found in treasure chests, both during and outside of battle.
