You place too much trust in your Magicks!Auron, Final Fantasy X
The formula for Magic Break is as follows:
- $ [(Magic * 75)/100] $
Magic Break is found on Auron's section of the Sphere Grid and halves the target's Magic Power. It can be healed by Dispel, and ends if the target is KO'd during battle. It can also be inflicted via the Full Break ability, also found on Auron's Sphere Grid path and via some of Rikku's mixes. Some enemy attacks also inflict it upon the party. Some enemies are immune against Magic Break.
Magic Break is used by the Warrior dressphere for 4 MP. It takes 30 AP to learn. It deals physical damage to a target and decreases their MAG by -2 levels. It also appears in the form of Magic Eraser, usable by Rikku while in Mascot, which targets all enemies.
Mind Break is an enemy ability used by Ahrimans. It lowers the max MP of all targets in its area of effect.
Addle is a Technick which halves one foe's Magick Power. It has 66% base accuracy and can be used repeatedly, but is not as effective on repeated uses. Once the effect has been applied, it is permanent, and the opponent can't remove it. Addle can be bought in Rabanastre and Archades for 3,500 gil, and can be used for 30 License Points.
Defaith is a negative Status Effect in Final Fantasy XIII that significantly lowers the target's Magic damage. Target with Defaith has their Magic power decreased by 88%, and also affects the party's magical Full ATB Skills, Hope's Last Resort and Vanille's Death. Defaith cannot be inflicted by the player party. It can be cured with Esuna or Dispelga and can be canceled with the Faith status.
Magic Break, known as Rend MP in the PSP remake, is an ability available to the Knight job class, learned for 250 JP, which reduces the target's MP. It reduces the target's MP by approximately half (rounded up). The Knight also has the Mind Break (or Rend Magick in the PSP remake), also learned for 250 JP, which reduces the target's Magick power. This reduces the target's Magic Attack stat by 3.
Rend Magick is an ability used by the Soldier and Warrior job classes, which lowers the target's Magic power if the target is in weapon range. It is learned for 250 AP through the Buster Sword for the Soldier and Warrior. The ability Rend MP is learned by the Warrior for 250 AP from the Falchion and by the Soldier for 250 AP from the Ancient Sword, and damages a target's MP. The Raptor also has the ability Soul Crush, which in addition to depleting the targets MP, deals damage. It is learned from the Falchion and requires 250 AP to master.
