Sugar cane is a good way if you have a lot with 1 stack selling for 192 coins. Pumpkins are the 2nd best way to make money, with 1 stack selling for 256 coins. Melons sell for the most with 1 stack selling for 576 coins. Way #4(Farms) This is an easy way to get money : This is the best way to get money in a matter of minutes. You usually have to already have lots of money for this way depending on the item. You could buy the materials for around 2.5- 2.9 million from the witch in the potion brewing hut thing and sell the sword for 3 million making a 100k profit(This may vary depending on how many spiders eyes you already have). Way #3(Merchants) This is a medium difficult way to make money: Merchants can be very useful for selling items and making money. This is not recommended for new players as you may lose money. They could also bid a very low amount and you could lose your money(you won't lose any money really if you grind for summoning eyes). If you're lucky some people will want an item so bad they will overbid by a huge amount. People want the best armor they can get for the cheapest amount of money and will pay low amounts to try and get what they want. Now here is the risky part, selling to the Auction House. This can be very useful in getting better stuff/more money for only 1 million coins per book. If you already have a lot of money I recommend at least getting Dragon Hunter I. Once you get you're summoning eyes the loot you get depends on the amount of damage(which will get you places on that leaderboard) you do. You could grind for them which usually takes a very long time or you could buy them like mentioned before. So usually to get something good you need at least 2 eyes. I made a guide on how much each dragon armor set sells for so go check that out for prices. To summon a dragon you need a summoning eye which are typically 400-500k on the auction house.
Now this is a risky way to grind for money but if you're lucky you can make a ton of money. Way #2(Dragon Fights) This is one of the harder ways to get money and is recommended for end game players: Another way to make a ton of money very quickly is dragon fights.
For instance the Pigman Sword, is 1.2 million pork but if you have the recipe you could simply buy the materials with money/trade for them and sell it for more than you bought it for. Minions are useful in this process because they help you get collection points for recipes of important items. Way #1(The Auction House) This is the easiest way for newer players:If you want to make a lot of cash over a couple hours/days you need some minions.
