If somehow, you have missed out on catching the Regi trio the last few times they were in the game, now is your time to have another go at it as Niantic announce the special Raid event.
The three Legendary Pokemon Regirock, Regice, and Registeel will be coming back for a limited time. Starting from the 1st of November until the 4th of November, players will find the Pokemon in the five-star Raids all over the map.
Also, Pokemon that are more effective against the trio will also be appearing on the map for often now so you can try to capture them and use them to take on the titans. Pokemon like Geodude, Swinub, Speal, Aron and more will be appearing more frequently now.
Niantic is also preparing to bring Regigigas into the game for the first time in EX Raids or you can purchase the event ticket and get a chance to encounter it earlier on the 2nd of November.
