Strength[edit]
Strength determines the physical power of your character. The higher your strength, the greater your attack power is. Strength also determines the amount of damage blocked on an enemy attack when using a shield in your off-hand. Rogues and Hunters only use part of their strength value to determine their power.
Agility[edit]
Agility improves your characters armor rating, chances of dodging an attack and the chance to deal a critical strike with either a melee or a ranged weapon, which provides greater damage than normal. Rogues and Hunters also use Agility, in combination with Strength, to determine their attack power.
Stamina[edit]
Stamina affects your characters hit points, regardless of the class. Warriors and Paladins however, are designed to absorb damage and will therefore gain more benefit from this attribute than other classes, like Rogues and Druids. Spellcasters, like Warlocks and Mages gain the least benefit.
Intellect[edit]
Intellect improves the mana pool of classes who use mana to cast spells. For classes that have no mana pool, like Warriors, it increases the chance of increasing a melee skill.
Spirit[edit]
Spirit determines the regeneration rate of the characters health and mana points. Higher Spirit points result in a higher regeneration rate, while low spirit point will result in a reduced regeneration rate.
