The Box Method
This is a golden oldie: you buy an equipment box or a book box or an enchant box or some other box, open it up, and sell the result. As of this writing, a shogun equipment box is selling for 240,000 gold. And yet a ghost warrior heavy armor, which can be found in the box, sells for nearly 4 times as much!
For the uninitiated, you might be saying what, what, what, what, people are dumb! but it's a rather simple economic principle. The more processed a good is, the more money it will sell for. Take raw shrimp, for example. I'm a cooking elitist, I like to make everything from scratch and so a bag of fresh raw shrimp might cost me $5. But on Tuesdays I become exceptionally lazy, so let's process it some more, let's say it's been de-shelled, de-veined, and pre-cooked. Now that same bag is $7. Let's go the extra mile and say on top of being de-shelled, de-veined, and pre-cooked, it's also been spiced up with Chef de Gustave's famous cocktail spice mix. Now the bag is $8.
The box method works on basically the same principle. Someone is paying you for having the fortune of finding the specific piece of equipment they wanted.
Though often touted as a source of experience, quest resets can also be good money makers. In early levels, your options are limited, but there remain several good opportunities. Mercenary recruitment quests can be repeated to obtain the summoning marbles or other goodies (like the small marionettes in the Witch quest). At the 80-90 level range, inventor and necropolis ring quests can net you an extra nickel to buy some soda pop at the store.
Once you get into the higher ranges, though, many veterans suggest that the repetition of certain quests becomes a necessity. This starts, at least in my experience, with Knud, found in the Frozen Adlivun. For a relatively minor number of steps, you'll get a whole bunch of experience and gold and a final reward of 3 Freezing Boxes. Once you've so thoroughly exhausted Knud, such that if you ever see a Chimera again you're liable to vomit, you can move on to James the Pretender, whose final reward is 3 Divine Boxes. Plenty of other quests will do, though the above two are some of the most popular.
And, since Ndoors recently increased the maximum number of quest resets from 50 to 100, you can enjoy double the Chimeras!
Ah, vice. Nearest and dearest to my heart. If ever there was a MMO in which gambling was an option, it would be Atlantica Online. The game's very lifeblood, its item mall, is based upon the gambler's addiction: just one more Hercules box for a hydra!
I hesitate to include gambling as a method for making gold as, nine times out of ten, you'll end up short, but... what am I saying?! Everyone loves to shoot for the big score! Just be careful you don't end up gambling away the armor off your back. Here are just a few of the options for gambling in AO:
Box-opening: many high-end nation or guild dungeons reward expensive boxes that contain items needed to recruit the game's best mercenaries. Evil Protector Boxes, which come from the guild dungeon Valley of Oblivion, have a rare chance of containing a Crystal Ball of Harmony (aka a cboh) which will be worth at least 1 billion and probably much more, depending on your server's economy. Others include Nimrod Boxes, Prison Safes, and Pirates Chests. The boxes are quite expensive, though, and can result in you throwing your computer out the window after you get your millionth mandragora.
Medici's Gold Box: a newly implemented feature, and obviously a gambling gold sink, where you spend 1 million gold for boxes that contain mostly experience books but have a chance of containing a rare weapon such an Officer's Shotgun or a Stormbringer. I've only seen a single rare weapon pop-up on Delphi, but there you are.
Arena: Every 4 hours (3, 7, 11, etc. EST, or GMT-5), 8 mercenary heroes and one of their several pre-set formations are randomly placed in a tournament against each other. Using the game's sometimes frustrating AI, they battle it off until one is the champion. Either remotely or through Maximus in person, you can place bets on the winner, the 1st/2nd match-ups, and the final rounds.
Going into the full ins and outs of successfully gambling on arena is an article in and of itself (I have a suspicion that it will be coming soon), but I can offer a few easy tips. Learn to recognize the strong formations: any formation with several Red-tooths (Red-teeth?), Alexandra with lots of spears, Hasard with a back row of gunners, etc. Likewise learn to recognize the weak formations: any formation with Raphael or Alkinarpay, archer heavy builds (excepting when combined with Guan Chang), or other bad mix-ups. Keep an eye out for high-dividends. When I was first getting into arena, I would often put minimum (10k) bets on high dividend 1st/2nd or final round match-ups because, even though they had a low chance of winning, you can never be certain with the arena AI.
In short, don't despair about inflation. Sure, it's tough to see everything going up in price, but one of the major draws of Atlantica Online is that the market has everything. When that's the case, you end up with a complex economy, where every little change can cause far-reaching and sometimes unintended consequences. And, call me crazy, I think that's really cool.
