Exlixir at event's close
I'm just guessing of course, but I bet you can use it on walls and junk..... Lol No, seriously, I doubt you will be able to do more than that.

OP, you can wait until near the end and see, but I would guess there won't be anything else offered for this event. Also, when this ends on the 7th, the Halloween event will start immediately after Clash of Clones. So, spend it before the changeover.
