Hastebreak is a Blue Mage spell learned in Final Fantasy Tactics Advance that can do one of two different things. If the target is at normal speed (not affected by Slow or Haste), then the target is inflicted with Slow. If the target affected by Haste, then they will be Stopped. Hastebreak is learned from Coeurls, or better known as Blue Panthers. It costs 12 MP to cast.
