[Lagarto]

Im willing to buy something like a costume or mount, but nothing currently there appeals to me. How often does it update?

There is new items comming at least once a month. Here is the showcase for what will come this month

crown store update usually once a month, and before each update they will list what will they sell on crown store on certain date for that month
