This may sound boring to you but farming for fossils pieces in CZ is a great way to farm.....I have a clan member who over the years was hacked twice.....once before the OTP system came into effect....while he was waiting on his restoration to his account.....he was able to go out daily and farm fossils pieces.....he managed to gear himself right back up before his restorations came in.....mind you at the time each piece of his krowaz was 950m for each piece and this was not including his accessories or weapons....and you never need to use any pots on the fossils which can safe you money.....Farming ancients, treants for those enhancements scrolls are another good way to make cash.....and if your are anything like me ...I farmed them mostly for Monster Stones, and killing bosses for drops is another good way to make coins.....I have a lot of farming tips where you can still earned exp along the way, or making fast cash another way.
And as what my Dear Old Friend Steve said is also great way to make noahs.....You be surprised as to how many noahs a player deletes their unwanted loot daily......an average player when they deleted their unwanted items are throwing away nearly 10m daily....so this gives you a lot to think on.
