Abyss Teskat

It's a hunting event that is going on until the end of March. The Rift Dragons are free, as long as you can find them. They are all hidden within the main store. You just have to look around for these little, green cubes and follow the clues. You can get the clues by going up to the big, green sign when you first teleport in, and looking up. At the top of the sign, you'll see a floating, green cube. Click that, and it will give you all the information you need to find the dragons. There are 6 Rift Dragon avatars total. Good luck.
