If uw and FoW arnt ur style i highly recommend the following.
Choosing an easy place to farm tons of things in HM can be very profitable, too.
An ss Necro zehlun run in hard mode takes 2-3min(lets go with 3 for merchanting/load times/etc)
Thats 20 run an hour. Each run you get anywhere from 100g, to an elite ranger tome, or a nice gold.(I got a req 8 brute sword once :P)
I would say on average you get at least 1-2k each run. Some runs you will get nothing or few drops, while others youll get normal tomes or an elite tome or a nice gold. I find that between merchanting crap and selling tomes i make about 1-2k an hour.(selling time for tomes varies) I usually just stock up on tomes and bulk sale on guru or if i see someone buying in kamadan. I dont waste time spamming **WTS: Ranger Tomes**.
With 1-2k a run on average you make around 20k-40k an hour. But getting more is very possible. Most i ever make was 80k an hour.(Got 6 Elite tomes, and 16, lots of merch crap and 100g drops.)
Whats also pretty important when farming is to set up a schedule(i know it sound cheasy but bear with me)
Lets say you make a commitment to farm 30min each weekday and 1 hour on one weekend day and 1 hour 30min the other weekend day. This should be very doable for many people.
Thats a total of 5hours of farming a week. With something such as the Zehlun farming from above Thats 20k-40k an hour you would be getting about
150k a week. But with a nice gold drop could be way more.
600k a month is not that bad.
The only Counter to this farming style is "Anti-farming code" which most people believe still exsist. So switching farming spot and/or doin missions and quests might have to be done too.
Anyway, this defiantly isnt he best way to make money out there, but it is a good start for beginner farmers.
