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) is an Ars Magus which helps reduce the burden on the body of its user when said user begins the usage of massive abilities. Kagura described it as being a burden and dangerous. In the case that one was incapable of properly controlling it, the user's soul could even be sucked into the Boundary. Through the utilization of the Azure Grimoire, it is possible to effectively reduce the risk.
