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, 
Viper, and any 
physical ranged DPS job; these jobs tend to use Dexterity instead.

- Thaumaturge auto-attacks scale so slowly that they will generally deal only 1 damage at levels above 50.
