I use cheatengine for cheating this game, use Ctrl+Esc instead of Alt+Tab.
All value Scan type is String, every value you change must have .0 or the value in the game will change drastically
At the beginning either accept or deny the guide from the old man, but with his help, you can advance some combat skill early and safely.
1/ Edit your money and give yourself a big number since you will need around 500000 to be sufficient.
2/ Look around all the vendors, if you can see a recipe or some expensive item, you are in luck. Buy the recipe or item to increase the exp of the trading skill. Look for the value and sell the recipe to the vendor to change the exp again and you got the Trading Exp, time to look for the Trading skill value, just increase the Trading Exp a bit for the value to change and get it. Once you got those two, proceed to step 3,
3/ Increase the Trading Exp so that you will get a ship point, then change the trading skill value back to 1. Then increase Trading Exp again to get another ship point. Look for the ship point value to edit.
4/ Time to increase personal point. To do this, you will have to increase personal skill. The easiest is luck. Go to tavern and play card or dice once. Same drill as Trading skill.
By now you can increase either the luck or trading skill to max out at 100. But remember, just one of them for now since we still need the other. Proceed to step 5.
5/ This step is for increasing the max energy for your character since you can edit health and max health easily. Look for the Rank exp, increase the Trading or luck Exp a bit, around 1 or 2 k is enough for the Rank exp to increase slightly so to can get it. Increase the Rank exp to 31, your rank will increase by 1. Look for your rank value, change and freeze it at 1, after that, increase your Rank exp to 31 and freeze it. This way your health/max health and energy/max energy will keep increasing, but since your rank is freeze at 1, there will be no problem with quest later on. When you think your max energy is sufficient to your liking, unfreeze the rank and rank exp.
