Overdrive is the Final Fantasy XI Puppetmaster's two-hour ability. As a two-hour ability, it can be used only by Puppetmasters and is not available to those using puppetmaster as a subjob. It may be used once every two hours. Overdrive will make a puppetmaster's Automaton immune to overloading. If the Automaton is currently overloaded, it will recover more quickly, but Overdrive does not make it instantly go away. Overdrive will significantly increase attack and defense of the automaton as well as greatly increase the strength of their abilities. The two-hour has no effect on the actual puppetmaster though.
