Rock Peak Ruins (Sinnoh)

The Rock Peak Ruins are a special cave in Route 228, in the middle. If the player heads down, there’s a hidden cave by a rock. If the player enters with Regigigas in the party, then the player will go to a new cave instead of the empty one with Nevermeltice in it. Here, the player needs to step on the dot pattern on the floor, then walk up to the statue, Regirock will attack, it is at level 30.
