A pet job of some kind. Way ffxiv works, looks like atm only way to incorporate pet job is to have prime skill a melee or ranged attack, and summoning the pet is a learnable skill, and the pet just auto-attacks whatever you use your prime skill against, each time you use it. The pet will only respond to learned skills and the master's prime skill, so using another class's prime skill with the pet won't make the pet do anything.
