Valor generally goes for 350k - 400k.
The supply of Valor has gone up noticeably lately; there are probably hackers farming this now. But with the new content and gear, it seems that the market demand can still hold the price for now.
I noticed that the price for Zeal is really nice too. A lot of people would offer 300k and Zeal scrolls sell really fast. I tried to buy one from marketplace forum and it took me 2 days to get one because of the insanely high demand -_-.
And I would not recommend you to farm Bloodlust. Although it's worth about 3 mil, the drop rate is WAY lower than Valor. I botted Regret for a whole night, maybe around 6 hours...and I got one, where as I can get 6-7 Valor easily within a couple hours.
You can try to bot Bloodlord hero mode if you just want to make gold.
I do it when I'm lazy to sell scrolls on the forum.
The gold it gives is decent, and you'll get a lot of empowered stones which are in really high demand right now because those rich people are trying to enchant their weapon to 10+. Each stone sell for more than 20k. And you can end up with 100+ stones in a night of botting.
