Final Fantasy VII/Command Materia

The Yellow Materia equips new commands to use during battle. Some types of yellow materia will gain new abilities as they mature.

Support
Materias that do not affect enemies directly.
 * Mime: Duplicates the last battle action performed by a party member without consuming MP or items. Limit Breaks cannot be mimed by characters other than the one who owns the limit, but every other battle action including counter attacks and defend can.
 * W-Item: Allows user to utilize two items from inventory at once. (See also: Item duplication cheat)
 * W-Magic: Allows user to cast two magic spells at once.
 * W-Summon: Allows user to cast two summon spells at once.

Debuff
Materias that target enemies but deal negligible or no damage.
 * Manipulate: Allows user to take control of an opponent and use up to three of their battle commands. While manipulated, a target's dexterity falls to negligible levels. Control will be broken as soon as the target takes physical damage. This is the only way to learn several Enemy Skills, though it does not work on all enemies.
 * Morph: Causes physical damage with reduced attack power on equipped weapon below 500 points. If the attack kills the enemy, the enemy becomes an item.
 * Sense: Allows user to see the stats (lvl., HP, MP, etc.) of a target. Not all enemies can be scanned.
 * Steal: Has the following abilities:
 * 1) Steal: Attempt to steal an item from a single target.
 * Mug: Takes the place of Steal of the command list when matured. Causes physical damage to a single target when attempting to steal an item.

Attack
Materias that deal damage to enemies.
 * Deathblow: Either kills enemy (dealing double damage) or misses. Effective on weakened enemies only.
 * Double Cut: Has the following abilities:
 * 1) 2x Cut: Attacks one target twice in a single round.
 * 2) 4x Cut: Takes the place of 2x Cut on command list when matured. Attacks four enemies in succession.
 * Slash-All: Has the following abilities:
 * 1) Slash-All: Attacks all enemies simultaneously. Attack is reduced to approximately 2/3 of normal and back row defenses still apply.
 * 2) Flash: Replaces Slash All on command list when matured. When successful, causes Death to all enemies.
 * Throw: Has the following abilities:
 * 1) Throw: Throws an item from inventory at a single target for damage.
