So currently in the gemstore, a package containing the Phoenix Glider appeared. It goes for 1360 gems, which is quite a handful.
The contents are:
700 gem Costume
500 gem Glider
??? gem 5x Dye's
600 gem Staff
350 Makeover Kit
Totalling at 2100+ gems being sold at a base of 1600 and a 15% discount bringing it to 1360 gems.
Already owning one of the items should allow you to remove item from the total price
I already got the costume, which by itself is 700 gems, which would make the base price 900 - 15% = 765 gems
