The Chosen Ones

1)Can you lower the price for potions and foods?
Its a pain to buy like for example, 6 Small Mana pot for 120 gold you see.
Worse, the gold I earned from killing and quest were not sufficient for me to invest in item recipe.
Or, you just want us to buy some (MUST buy) items like Azureus, Margarath, Archeon's stuff and not other expensive things like recipes, other equipment items (health/mana belt, Jade Ring or items to make synthesis weapon)

Or, you want us to save so that we can buy it later in Chapter 5 or 7?

Or, is there any alternative ways in earning gold excluding killing and doing quest?

2) Stealing is hard -,-
I'm so frustrated trying to steal from Voldro and the Centaur Boss,
Can you tell me the stealing chance? And where to find any items which can increase steal chance?
Or can you increase the steal chance slightly?

Look, in the early chapters you can forget synthesis, since you can't miss some set items. Later you get some from bosses that provide you with a good amount of bounty when you sell them.
About that stealing chance in chapter 2, try to get the item from Black Merchant first, it helps a lot.

About those highly cost items, they are calculated correctly and the prices of them should be about what they currently are. The idea behind this is that they are actually for Elite and Epic Bosses. You don't need to have them to finish the chapters. They however make you a lot stronger.
