There is one, but it's just being a hunter
If you're asking how to maximize profit at lvl 5/6 for luan maybe or max money, then what you will be doing is hunt only on rainy, and all the other time, you would just do prof. With a steady increase in exp, you will still max the chances of money with ee/skulls sold + profession.
Example: i'm a herb/alch, and say i do rainy on lvl 5. Roughly in 2 hrs i should kill 3 zombies in 2 min, and so in 2 hrs that's 180 zombies. that's a good pace and good chance for ee. Also, doing prof, say... making giants, i make say 200 giants, that's roughly 10g also. If you really think, at lvl 5 you can gain a huge amount of money just by doing hunting ONLY on rainy and the other times just doing prof. That's all i can say so far. It will be same on lvl 6 but you can make more money because of the whole new array of prof things which are in great demand as well as that ee/skull drop rates can be almost similar as lvl 5, maybe a bit less.
