Will 2x boss lix work later

[Crystalwiz]

Can you tell us if the 2x boss lix will work after this week's event.

[Pleasant]

I think it would still work after this week. I don’t see the point in adding the elixir just for one week and taking away our money

They can be used anytime, they're just only sold during the event.
