The Warrior is a melee physical class that will use only their weapon to deal damage.
Their primary stats are Strength, Endurance, and Dexterity, which should be balanced to determine the weapon, armor, and amount of health points (HP) you aim for.
Allocate your points in Attack and Evasion to ensure you hit and dodge most incoming attacks. (For Endgame, an attack rate of around 1000 - 1200 helps avoid missing too much if you have the Superior Instinct spell, otherwise aim for 1300 - 1500 and the rest in Evasion).
Invest a lot of points as soon as possible in Power Shot, which makes your attacks significantly stronger.
Only learn the Piercing Armor skill when you reach the 3rd island (Stoneheim, also known as SH), as before that, few monsters have significant armor.
The specialized skills to learn are Stunning Strike, Power Shot, Piercing Armor, and Parry. Quick Healing should only be learned if you have a minimum of 230 points in Endurance.
