In the final regi ruin dungeon, there’s a choice. This Regi Ruins Draconic Or Electric Pattern Guide Sword & Shield will tell you both how to make each pattern on the floor so you can challenge the Pokemon type you wish, and details on which Pokemon emerge depending on your choice.
Much like choosing what Carrots to plant, this particular choice as a limited choice that is permanent. Whether you pick the Electric or Dragonic pattern is entirely up to you but it does influence what Pokemon appears and it influences what Pokemon you will get to catch. You do not get to make this choice again, so you can only keep one of the Pokemon.
This pattern above is for the electric Pokemon. The order in which the lights are lit does not matter, simply put the lights in this pattern. Choosing this pattern has you fighting a Regieleki Pokemon. It is electric and goes down really easy, so be careful when hitting it.
Regielki starts with Thunder Cage, Electroweb, Extreme Speed, and Magnet Rise.
This is the second pattern, the Draconic pattern. Much like the Electric, the order does not matter, simply have the same pattern lit to challenge the draconic version of the boss. If you choose to go with the Dragon pattern, you can fight at catch Regidrago.
Regidrago is a Dragon type Pokemon. He is caught at level 70 and starts with Dragon Energy, Dragon Claw, Hammer Arm, and Laser focus.
