Too much material such as half blood idol to make stuff and it's hard to find them, i haven't seen anyone can collect all of them :( why not drop per monster? No parents will allow their child sitting at monitor too much and my eyes are hurt because of spending 2 hours to collect essence @.@ I think you should make it drop 2 essence every 100 mana and each eye remain in 1 hour. If the admin team can do that i don't have to waste so much time on collecting and my mom will stop yelling at me more often "> Thank you very much ">
