it's totally possible if you follow the event quest list and time what you do accordingly, you won't even have to log in at work. the quest list is the same in every maiden event. i am a free player and i usually can unlock the legendary maiden with two days left in the event. i always stop at quest 29 and by the end of the 7th day i would have accumulated 20k - 22k silver coin. just enough for the "open 1 event" chest" quest and then a 10x draw for 18,000.
