Affects physical damage dealt by gladiator's arms, marauder's arms, pugilist's arms, lancer's arms, arcanist's arms, dark knight's arms, samurai's arms, reaper's arms, gunbreaker's arms, red mage's arms, astrologian's arms, sage's arms, and blue mage's arms.
A brief summary of the relevant classes (or jobs) that can be affected by the stat is shown below. Note that for most jobs, their only source of physical damage is melee auto-attacking; for example Strength won't affect their damage from Spell-type actions. In short, the exceptions that are unaffected are Ninja, Thaumaturge, and any physical ranged DPS job; these jobs tend to use Dexterity instead.
