Crown Tundra · one save, one giant
How to get Regidrago
Regidrago is a Crown Tundra encounter. Catch Regirock, Regice, and Registeel, walk them into the Split-Decision Ruins, and light the dragon pattern. That save file can catch only one of the two at these ruins; trade or HOME can still bring in the other.
Crown Tundra Legendary Giants: Regieleki and Regidrago. The player stays empty until you press Play.
Where to play
There is no browser build of this encounter. Pokémon GO is the phone app. Sword and Shield plus the Expansion Pass are Switch games. The three doors I trust are the store pages themselves:
The Crown Tundra release date on the encyclopedia page is 23 October 2020. That date is one source. The Expansion Pass is required; the base game does not contain the ruins.
The three titans, then the pass
Bulbapedia and IGN agree on the gate: catch Regirock at Rock Peak Ruins, Regice at Iceberg Ruins, and Registeel at Iron Ruins, then lead them to the Split-Decision Ruins at Three-Point Pass so the door reacts. IGN’s walking route, which I am treating as one source, starts at the bottom of Giant’s Bed, follows the riverside path into the cave, crosses to the Frigid Sea, lands on the small beach, and turns left at Three-Point Pass.
| Row | Left | Middle | Right |
|---|---|---|---|
| Top | Lit | Lit | Lit |
| Middle | Lit | Dark | Lit |
| Bottom | Dark | Lit (middle pair) | Dark |
After the statue wakes
The encyclopedia page says the pattern cannot be reset once you interact with the statue, and it lists the encounter at level 70. Both of those lines are one source. Regieleki’s pattern is the other drawing: the left column and the right column fully lit, plus the third cell up the center. Light the dragon if you want Regidrago. The same save cannot catch both in the ruins, but can hold both after trade or HOME transfer. Two community guides describe a second Switch profile, a fresh adventure, and a Pokémon HOME move if you want the pair. I mark that rescue as 2 community sources, not as a Nintendo tutorial.
German queries for a Tauschcode are asking for a link-trade password between two players. There is no official Regidrago redeem code, and I will not publish a made-up four-digit stand-in. Scarlet and Violet only receive it through HOME, one encyclopedia line. Legends: Z-A is listed unobtainable on that same page, so this guide does not invent a wild location there.
Questions people actually ask
Where is Regidrago in Sword and Shield?
Split-Decision Ruins in the Crown Tundra, after the three original titans are caught and in the party.
What symbol do you light?
IGN: all three top lights, the two outer lights of the middle row, and the bottom two in the middle column. One written source. The statue locks the pattern.
Can one save get both Regidrago and Regieleki?
The ruins provide only one encounter choice per save. You can still own both through a trade or Pokémon HOME transfer from a compatible second save.
