I thought my comment is deleted that's why I'm posting again.You dev team,money suckers.I've spent abt 100 or more and your system sucks.I've spent almost all of my gems to get a single 7stars quest in tarven.I've rolled a single quest for only 10 gems and yes it's almost consumed all of my gems but the quest never appeared.For the starter who want to try don't even give a try cuz they always look for the ways to suck out your precious money.I want to give zero star if possible.
