v.128 - Year of the Snake Update Notes

I would claim the reward today if I was you, the event tab thingy says that it ends today and I wouldn't risk waiting.

Well, either I get it today, I can't use it before it expires because of 18 slots, or I risk it out and try it later with same results if I fail. And since I'm a lv 200, the x2 exp is useless on me. So yeah, I'll wait a bit more for now... Unless there's a way to make the 7 day limit go away :p
