Finding Regice in Emerald is a challenging but rewarding task. Regice is a powerful Ice-type Pokemon that can be a valuable asset to any team. To find Regice, you must first obtain the Regirock and Registeel. Once you have these two Pokemon, you can use them to access the Sealed Chamber, where Regice is located.
The Sealed Chamber is located on Route 105. To get there, you must use Surf to cross the river and then use Rock Climb to scale the cliff. Once you are inside the Sealed Chamber, you will find Regice waiting for you. Regice is a powerful opponent, so be sure to come prepared.
