once you get to level 100 the money starts rolling in, recipes sell for 15k each, monsters drop more money as well.
arde works so amazingly well since it’s damage applies to every extra hit, so your sacrament double dips, same with fire enchant. if you were another class with active multi hit skills it would apply to all those as well, which explains the increase in price: pretty much every class and build gets a huge damage increase from using arde in the offhand
you always attack with your main hand only, if you are not a corsair, who gets a passive dual wield buff.
