how to get edana coins quickly and save water :
1. prepare 3 accounts with cp equivalent to your main account
2. make sure your main account is in oasis
3. kill every monster that is near the altar with the second account (do not take the altar)
4. take the edana coins at the altar with the main account

note : I've never tried this,but i think its a great idea
