Power Stone

There are two main types of Power Stones: the Mighty Stone (Japanese:パワフルストーン Powerful Stone) and the Sturdy Stone (Japanese:タフネスストーン Toughness Stone). Mighty Stones boost a Pokémon's Attack, while Sturdy Stones increase the Pokémon's HP. Stones which provide greater stat increases can be obtained by defeating stages of greater difficulty.

The Power Stones must be placed in an open socket in the Power Charm to have its effect. A Power Charm has a maximum of nine sockets and these sockets are unlocked as the Pokémon gains levels. Certain sockets can accommodate both Mighty and Sturdy Stones, while other sockets are restricted to one or the other. Each Pokémon have different Power Charms.

There are rare Power Stones that may give extra boosts on top of Attack or HP. These are colored bronze, silver or gold. Bronze Power Stones provide one extra boost, silver Power Stones provide two, while gold Power Stones provide three additional boosts. These boosts include:

• Critical Hit Rate (%)
• Critical Hit Damage (%)
• Natural HP Healing (%)
• Hit Healing (%)
• Healing from K.O. (%)
• Time to Recover (%)
• HP upon Recovery (%)
• Resistant to ↓ Effects (%)
• Resistant to Status Conditions (%)
• Movement Speed (%)

After every 10 successful expeditions, the player will earn an Expedition Bonus. When the bonus is active, the player will earn more rewards from expeditions, including a gold Power Stone. The bonus disappears after one successful expedition.

Power Stones can be recycled to obtain ingredients for cooking. The player is initially able to store up to 20 stones. Stone box expansions can be bought at the Poké Mart for 50 PM Tickets to increase the storage capacity by 20 (max 300).

Move Stones (Japanese: わざストーン Move Stone) are special Power Stones that can increase the performance of certain moves. Each move has 0 to three sockets where a Move Stone can be placed. A Move Stone can only be put in a socket connected to a move that has the same color as the stone. There are six kinds of Move Stones, each with different effects.
