Warrior-based classes are classes that have Warrior as a prerequisite or is Warrior itself, excluding Ninja. These classes include Warrior, Spellsword, and Hero. If a user with a warrior-based class uses a weapon that has a benefit marked as warrior-based, that benefit will be in effect when using the weapon.
With 21 different weapons, Warrior-based jobs have the largest number of weapons to choose from. With the exception of Chapter 2 lacking a Warrior-based weapon, all other Chapters offer a variety of weapons that can be bought or found, making it easy for a Warrior-based job to get the 30% bonus damage in battle.
