Pokémon Mystery Dungeon: Explorers of Time Tips

Multiple Use of Gummies
1. Get something that will give you Pierce status (Pierce Orb, Pierce Band, the Pierce Thrower IQ skill, etc.) but only have one item for Pierce.
2. Have a Pokemon you don't need to raise the IQ of have the Pierce item.
3. Fill the rest of your inventory with Gummies (works best with 6-page inventory).
4. Go to Beach Cave.
5. Have the 3 Pokemon who you want to raise the IQ of in a straight line behind you and give yourself Pierce status.
6. Finally throw the Gummies through your 3 allies to increase their IQ all at once, if it doesn't miss one of them.
