Overdrive (gameplay)

Overdrive is a new system introduced in BlazBlue: Chronophantasma that replaces the Gold Burst from the previous games. Ovedrive builds up over time, after which it is activated by pressing A+B+C+D. Overdrives increase attack power and grant character-specific benefits. Its duration depends on the character's health, generally lasting from about five to fifteen seconds, with more time being added the lower the HP amount. When used, Overdrives freeze the stage timer.

Within Story Mode, Overdrive (術式強化, Ars Magus Strengthening) is an Ars Magus which helps reduce the burden on the body of it's user when said user begins the usage of massive abilities.
