Pulsing

Power is one of the material types from the Kingdom Hearts series used in Item Synthesis. Representing strength, the Power materials remained essentially the same in purpose between Kingdom Hearts and Kingdom Hearts II

Kingdom Hearts
The Power materials, like the other major synthesis materials in the game, came in three forms: Shard, Gem, and Crystal. Like many of the other materials, they also acquired a fourth form, Stone, in Kingdom Hearts: Final Mix.

Drops

 * Power Shard: Bouncywild, Powerwild, White Mushroom (when Stop is the last spell used)
 * Power Stone (Final Mix only): Sniperwild
 * Power Gem: Air Pirate, Battleship, Pirate, White Mushroom (when Stop is the last spell used)
 * Power Crystal: Wyvern

Kingdom Hearts II
Like many of the basic synthesis materials, the Power materials went virtually unchanged between the games; the Stone version was included in the regular game this time. They are also one of the basic eight materials, and so collecting 30 Power Shards, 25 Power Stones, or 20 Power Gems will unlock those items for purchase in the Moogle synthesis shop. Power materials were assigned a dark blue color to distinguish them from the other materials.

Drops

 * Power Shard: Creeper Plant, Large Body
 * Power Stone: Luna Bandit, Silver Rock
 * Power Gem: Aerial Knocker, Shaman
 * Power Crystal: Morning Star

Purchase (when opened)

 * Power Shard: 100 Munny.
 * Power Stone: 200 Munny.
 * Power Gem: 400 Munny.
