Rule Ten Buy Items in Bulk. Cheaper items are still effective if used correctly. Buy lots (max is 255 per slot I think) and they'll last you several days at a fraction of the price of several of the stronger items
Example Stanching herb - heals 20 external wounds. Sells for 10 9 dragons gold each
255 X 10 = 2550 Does that NOT save you time and money?
you can stay out in the field and gather more thing before needing to return to town. thus higher income rate and less time wasted of running back and forth to buy more of those expensive herbs that cost a bundle every time you do it.
I did that purchase I was out for at least 12 hours each for two days before I had to go back and buy more. Took me quite awhile and I was fighting those nasty little red foxes that hit criticals 1/3 times they attack.
>>Sidenote<< The higher your wound count (100 and up) the % of the price you pay is around 50%. 400 wounds = 200 9 dragons gold. Just incase you didnt stay on top of managing your wounds while in the field.

The final Rule Technically its the 11th but this applies to everything including real life so its not exactly part of the ten rules.
Be patient! evetually your patience will be rewarded for your hard work. In game your character will not only have the best weapons at the point also have cash to spare in case of an emergency not to mention your skills will be very high. This cant be beat. Granted you got to resist hurting someone so have a sibiling around to pummle or even better multitask like watching tv every 20 min so you dont get bored!
