Split-Decision Ruins Regieleki

After the player captures Regirock, Regice and Registeel at their individual ruins in the Crown Tundra, the player can go to the Split-Decision Ruins and choose to encounter either Regieleki or Regidrago. The choice is made by illuminating the floor tiles to match the design of the dots on the wanted golem's face. Once the choice has been made, the decision cannot be undone, even if the chosen Regi has yet to be caught.

In order to open the door to enter the ruins, the first requirement is to have players capture Regirock, Regice and Registeel on that save. The second requirement is for Regirock, Regice and Registeel to be in the player's party while interacting with the door. These 3 can be of any origin (doesn't matter if transferred from HOME or caught in Crown Tundra).
