To get Regice you will have to beat the game-you will also need a fire x3 ability, a cross ability, and a break x2 ability.
First go to Fall City. Then go down into the cave. From the entrance follow the path until you get to some Jynx. Then go follow the path more until you get to two Golems. Then use fire x3 on the bottom ice cube and go inside. Then use break x2 on the right rock and go down. Use cross to the left side and then go through the giant doors. Regice will be there.
