Bought alongside a Haunted Ghosts Whirly Warrior for 1150 keys (Probably => Everything else matches with others, so keys likely match with the two items)

No sales on the Whirly, just as a "what if" scenario I'll use the outdated price

1150 - 272.5 = ~878 keys

Planning on using this for the Cloudy Moon Killer's Kabuto

Total Sales

680, 878(?), 950, 960

878 uses an outdated price by 2 months

I'll just run with 950 - 960 keys (Unless 880 should be included here?)
