I'm a bit more of an investor. I don't like the undercutting involved in raw materials and scroll selling, so I've taken to making gear and enchanting/enhancing them. My payoff is a bit slower, I sometimes lose equipment or fuck up the durability too much, but its usually pretty high. This method requires patience, but the payoff is huge - about 50 to 100M depending on the items you're selling, sometimes higher.
I run a bot pretty much 24/7 in two moons to fuel the elixirs (and impending scrolls).
I run a bot in fruitful or regrets... too late for valor and bloodlust scrolls (go for blood if I have tons of valor in stock).
I run a bot in Ruins of Sanctity for enduring scrolls for half a day, and then switch him to Rocktune's Cabin for Masters scrolls.
I run a bot farming the runs I need equipment from. This guy is the real time limiter, and I've been writing my own bots to farm specific missions, I often convert my other bots to help farm these runs.
I'm currently working on a new mining bot, my old one used to rely on map reload commands, but those are broken at the moment.
Almost all of these runs provide empowered enhancement stones.
I use AutoIt scripts, and will probably release them some day when I perfect this art, but I'm still fairly new to the scene.
I also have 299 goldsmithing on my main account, and I sometimes make 3 star accessories (from botted mats) then enchant them (with botted scrolls), but this technique costs unbind pots and I don't want people to get suspicious if I sold too many at once.
This method is basically how legit players make money, enhanced with botting so that I don't pay the material/time costs they do.
