Best buy has an exclusive set of armor too.
Oh, I had no idea! I never buy from Best Buy really, so I missed out on hearing about this one. The info:
Gathelatio Costume Set DLC which includes Planeswarden Garb, Chompette's Coat, Sagittarius Garb,United Garb
Anyone who preordered on Best Buy's website - did you already receive a code?
Also, I was just looking it up, but someone on another site mentioned that all these costumes are purchasable with in-game currency but could possibly be fairly expensive, so it's more like endgame grinding purchases. Additionally, these are all probably aesthetic-only outfits, offering no other benefits. Good to know in case you choose to not preorder.
