Rock Locations:

Color Location When Other Black Kajar 12000 BC Open the water, wind, and fire books (in that order). The Black Rock is in the secret room that will open. Gold Denadoro Mts. 600 AD With Frog in the lead, get hit by the Free Lancer that's throwing rocks. Frog will catch one, and it will become the Gold Rock. Blue Giant's Claw 600 AD Located in Tyrano's Lair, in a chest. White Black Omen 12000 BC 600 AD 1000 AD Silver Laruba Ruins 65000000 BC After saving Crono, talk to the Nu that offers to change the lead character's name. The Nu will just give it to you.

- You can’t use "Dark Eternal" in battle unless Marle, Lucca, or Magus has the Black Rock equipped as an accessory.
- You can’t use "Grand Dream" in battle unless Frog has the Gold Rock equipped as an accessory.
- You can’t use "Omega Flare" in battle unless Lucca, Robo, or Magus has the Blue Rock equipped as an accessory.
- You can’t use "Poyozo Dance" in battle unless Marle, Lucca, or Ayla has the White Rock equipped as an accessory.
- You can’t use "Spin Strike" in battle unless Frog, Robo, or Ayla has the Silver Rock equipped as an accessory.

Other:

- There are many many Magic Tabs that you can come across throughout the game. Using one on a party member will increase their Magic Power by one. This makes their techniques more powerful.
- Ether items restore MP. Have a lot in your inventory if you are going into a big battle, such as against Lavos.
- Crono's "Red Katana" and Frog's "Rune Blade" both have a stat increase of +4 Magic.
- The "Magic Scarf"(+2), "Magic Seal"(+5), and "Magic Ring"(+6) also raise the Magic stat.
- The "SilverStud" accessory makes the party member who has it equipped only have to use half of the required MP for any use. It does not raise or lower your attacks and techniques, it just makes the cost of using any Techniques or Magic decrease by half. Pretty nice thing to have equipped.
- The "Gold Stud" is like the SilverStud except it is more powerful. It decreases the cost of using MP to 3/4. If the Tech normally requires 20 MP to use, it would then only cost 5 MP to use if this nifty little thing is equipped on that party member. I would recommend equipping it on someone who uses up a lot of MP really quickly.
