No the CM doesn't determine the money you get.
It's the value of the objects you're selling making profits from 1 till 433 per item.
It works as follows.
I usually buy everything that a trader has to offer. (except for the weapons) The trick i used works with the travelling traders.
I stocked up with will potions , health potions , red meat and the gems i talked about earlier.
When i get my home i'll post a screenshot of the items that are best for selling and buying. I have about 200 emeralds. These can be found with the travelling traders in the darkwood regions. If i'm not mistaking the always sell 4xtofu and 22x emerald. These are your guys.
You need some guile points (3 or 4 should let you make small money profits).
Just put all your skill and general experience in guile at the beginning.This way you can max out all your skills very early in the game.
Now make sure you have around 50 of the same item. Go to a trader and buy everything he's got. This means he's completely empty. Thanks to your guile you'll be able to sell the same stuff for more money then you originally bought it for.
If you buy everything back now you'll get a cheaper price since the trader has a lot of the same items. In my case i sold 200 emeralds (worth 700 i think ) = profit 433 for 1 emerald making a smack of money. If you buy them back you'll pay around 250 per emerald. Make the maths and get filthy rich.
1 important thing , use the SELL ALL and BUY ALL buttons.
If you kill some bandits first you should be able to get a combat multiplier of 15-20. Since we are using our tradingSKILLS you'll be rewarded with lots of skill points for each buy/sell cycle. I got over 200000 points when i was finished buying/selling thx to my combat multiplier.
If you buy everything and you hotkey red meat , fish and carrots (you'll have a ****load of these anyway after a few hours) then you'll experience up very fast with a high multiplier.
I restarted and i have to kill twinblade. I'm already maxed out in skills and strentgh. It's pure ownage
Anywayz i hope you understand what i'm trying to explain. Feedback is well appreciated.
Have fun owning the game.
