It can be hard to make enough kamas as a low level but it is definitely possible. You'll typically be between level 30 - 40 before you're able to make profit. At levels before that you'll be spending kamas to build a production base and a client base. Unless you find that production base that no one has filled, you might be end up at level 100 before finding a profit.
As we know, many low level recipes are either not wanted or require huge investments in time and kamas. Here're some methods you can use as a low level player to make some kamas:
We would suggest playing the quests and getting a sidekick. Make whatever equipment you can. Then start doing treasure hunts or dimensional quests. Always be part of a group for XP and drops. Do all that well before making kamas and before seriously upgrading equipment.
There are a couple of things you can do, killing crabs along the river will almost always give you water in the x10 containers, there easy to kill and they come in pretty big groups. Almanax quests sometimes give much more kamas than what it costs to buy the offering for example.
Sell materials and gear to make your money. Check your markets and see whats selling, then go out and either gather or craft it. And if you can, invest in some idols, they really make dropping materials and resources easier.
Obtain perceptor potions - place perceptors in areas taht drop mats needed for perceptor potions - place leftover perc's somewhere else - harvest perc's and craft new potions and also some other stuff - sell a portion of potions and what else you crafted and repeat everything from step 2.
Perceptors allow you to obtain high level materials without actually being high level, but you need to be in a powerful guild.
