I've heard people argue that money is incredibly easy to come by in this game, and candles selling at 50g per may have been contributing to some of those reports. Nobody ever seems interested in talking about how all that money is being made, though (which is odd for an alpha/beta testing situation). Who knows if this had anything to do with it; perhaps there are other items like the candles out there that someone is intentionally not bringing up (which is disappointing, in my opinion).
Paintings sell for around 450g each, and there's plenty to steal in Cyseal.
Without these, though, I have no idea how I could make the money to buy skills or gear upgrades.
