I always I wondered how this server could manage to keep things at a lower price, and always I do fear that everything just skyrockets when money is put in circulation but then, I remember about the Shugo vending machine and I say.. why we couldn't bring back the shugo machine but adapted to our version?
The machine would sell stuff at Kinah only, I was thinking like some sort of "loot book" , divided intro diferent values for example:
100.000 Kinah box: Gold medal, minor AP icon, enchantment stone (max lv 50)
500.000 Kinah box: Platinum medall, AP icon lower to big, manastones lv 40
2.000.000 Kinah box: Chance of ceranium medall, in case of fail, 2 broken ceranium, enchantment stone max lv 90, ap icon small to grandiose, tiny chance of serum or feather.
The vending machine would not have shop items or stuff that does afect much game economy, of course what I worte is an example, but I am sure that well done it might help remove some kinah from circulation if need.
