The Warrior is the role most intended for front line fighting. They have the highest attack bonus and usually the best armor class of any role. They gain access to many powerful combat maneuvers to damage or disable foes.
Warriors have skill with a very broad set of weapons and can gain specialized proficiencies if desired. Most Warriors will wear heavy armor and participate in front line fighting. However, Warriors also have potential to be very strong ranged fighters.
Strength is the most important ability score for most Warriors, as it controls their ability to hit and do damage in melee. Constitution is also important for improving the Warrior's ability to soak up damage and protect other party members.
