There are a few things you can do to take advantage of this easter quest;
for example if you get heaven blessing as a prize you can get married for free!!!, and also double EXP when you kill monsters!!!
if you get an easter potion, keep it later to sell it for quite alot as well.
As everytime you talk to a monster you'll get 20 min worth of EXP, as you are only allowed to do this quest 10 times per day, see if you can change your proxy/i.p adress and log in again to do it another 10 times.
Hope these tips help
have fun
and happy easter
