Octopath Traveler has some fantastic illustrations so why stop at one cover? Well now everyone can chose between eight more covers thanks to Nintendo. One for each main character. Print them on actual size on letter-sized (8.5 x 11 in.) paper. Nintendo recommends using gloss text-type papers.
Here’s the catch, you need to spend 50 platinum points to get them and available until 1/1/2019 at 2 am ET and redeem only once. These points are easy to get but not everyone has those amount of coins. Thankfully, Reddit user sparkthedarkness has uploaded the files (see first comment) for everyone to download, bypassing anyone using their coins to pick up the covers. If you are thinking of downloading them, do it.
Additionally, Nintendo Rewards has the Octopath Traveler desktop and mobile wallpapers which costs you 50 premium coins. This is also available until 1/1/2019 at 2 am ET.
Octopath Traveler is available exclusively for the Nintendo Switch.
