Please, please do not make a great fantasy that is Pay to wim,
Do it in a way that is possible in all ways to be strong in the game.
Good and regarding the rate of the game, in my opinion would be interesting:]
sprites x10 exp
x10 exp characters
x10 gold for monsters
And I also suggest that you increase the rewards of gold per quest,
as it has been said if you are planning to make a healthy game other than
Pay to Win, quests are a means of making gold in the game and of course,
items like costumes, legacies and combat mounts are more easily acquired in
alchemy. And if possible increase the chance of making items successfully in
sprits, it is ridiculous that a sbk is needed every time you make an item.
