Potion Making, you can farm 500 Uosis/30 Min with thauma in Raskoy Lake, and turn into SP Potion(you need Dilgele to make HP Potions, you can grow it in Guild Tower, its a bit more expensive, but you can get some profit), or other usefull potion(not at all i guess, AoE and Block Potions are nice, but not worth to make it all the time, and Movement Speed Potion you can get from Uphill).
1 Uosis = 5 Potion
1 Potion = 1k Silver (SA Price, sometimes you can get 1,5k per potion, Depends on the demand and
market opportunities to increase your profit)
Shop (Gem roasting, better now thanks to Uphill, and Awakening Shops) when you are playing w/ other char.
the only real problem with this is, each potion(5) take 20 seconds to make(500 or even more take hours, special potion are made 1 by 1) so, leave the character make than, and do other stuff, like read a book/blog/novel, watch a video/movie, etc. In the end, you can make 2,5/3 Million in 2/3 hours a day (from my personal results, thats is way better than any shop).
