Magic Counter (まほうカウンター or 魔法カウンター, Mahō Kauntā?), also known as Counter Magic, and Magick Counter, is a recurring ability in Final Fantasy series. It allows the user to strike back when hit with spells, either physically or with the same spell, depending on the game.
Magic Counter is a Support Materia with a chance of countering with the linked Magic or Summon Materia. The probability increases with the Materia's level starting at 30% and reaches 100% on level four. Magic Counter can be found in the Northern Cave and is a prize in chocobo racing S Class.
The counter-effect can be stacked up to eight times on a single character, meaning that if the same character equips multiple counter-effect Materia they will counterattack multiple times (however, Final Attack and Sneak Attack Materia also occupy this space). It is possible to counter four times in a single counter if the linked Materia is also linked with Quadra Magic. Knights of the Round doesn't usually work with Quadra Magic, but if the player equips Magic Counter with Master Summon, and Quadra Magic with another Master Summon, there is a small chance to counterattack with four Knights of the Round attacks.
When linked to regular Magic Materia, the ability used as a counter attack will be the highest level ability in the current level of the linked Materia. Linking to Summon Materia will simply counter with the normal summon attack. When linked to Master Magic or Master Summon, any of the possible spells/summons will be picked at random.
If the Magic Materia is linked with a support ability that naturally targets party members, the spell will be used on the character who has the Magic Counter equipped, or the player's group, if the ability is area-of-effect.
Oddly, Magic Counter also appears on an armor: a Buckler, that can be bought from Rin's traveling hovercraft on the party's first visit to the Calm Lands. Since Buckler is the name for an accessory when no abilities are equipped, it can be assumed that Magic Counter was never designed to appear on an armor.
Magic Counter is a Berserker ability. It costs 300 AP to learn and involves a physical counter to a magic attack.
Magic or sorcery is an attempt to understand, experience and influence the world using rituals, symbols, actions, gestures and language that are believed to exploit supernatural forces.
