During your exploration of the Crown Tundra, you will have the opportunity to catch loads of Legendary Pokemon! Most Legendary Pokemon will be obtained through Dynamax Adventures; however, sixteen Legendary Pokemon, both new and old, can be captured in the Overworld. One of these select few Legendary Pokemon is none other than the brand New Legendary Pokemon known as Glastrier!
Players will have the opportunity to find and capture Glastrier while undertaking Peony's Legendary Clue #1, the same he calls The Sacred Bonds Of Sovereign And Steed, which focuses around the Legendary Pokemon Calyrex. As players progress with the Legendary Clue #1 Story, Calyrex will eventually ask for players to obtain carrot seeds from one of the townspeople in Freezington. With these seeds in hand, Calyrex will tell of two fields where they can be planted in the Crown Tundra. Depending on the field you choose, the Legendary Horse Pokemon Calyrex use to tame will differ.
If you want to eventually obtain Glastrier, you will need to plant the seed in the Snowslide Slope field. After you do, Calyrex will have you harvest a frozen carrot of ice. Later on in The Sacred Bonds Of Sovereign And Steed Story, Calyrex will then tame Glastrier and you will be able to battle (and this time attempt to capture) Calyrex Ice Rider. Should you ultimately capture the "fused" Pair, you can "unfuse" them to obtain Glastrier simply by using the Reins of Unity Key Item and having an empty slot in your party.
