Blizzard has announced that a new Switch amiibo will be sold at Gamestop starting in December for $15.99. The Loot Goblin is the first-ever Blizzard amiibo, but at this point, we don't have any idea what it will do. According to Gamestop, it "opens up a portal in game". It's possible it will function similarly to Goblins that currently exist in the game that can occasionally open a Treasure Portal that can yield serious gold and items.
Diablo III: The Eternal Collection officially releases today.
