Mayan crowns

Mayan crowns may only be used to buy artefacts sold at Merentesh's Shop of Wonders in Delos. Crowns are awarded for reaching various milestones in credit purchases from the official market: one crown at the 100 credit mark; two each at the 300 and 500 marks; five more at the 1000 mark; and 10 more at 2000. The maximum amount of crowns one may accrue via this method is 20, and crowns are currently available for a limited time only. Mayan crowns were introduced in Ero, 476 AF.
