Maybe a "who wants to be a millionaire" quiz based on Epic PW,
Idea daily event give one duty badge at any elder, to get questioner, if we answer 5 multiple choice questions based on Epic PW correctly in a row within 10 minutes we get 1 EC, while each question should repeat once a month at random order.
we need 5*30=150 questions about PWI in a mounth.
And you can replace question once in 2 months.
A example
1. What is the name of last boss in Frost covered city?
a Holeen
b Hoolen
c Helloween
d Oceania
