This system actually took me quite some time to understand, having read it for over 10 times. Well, here’s a short introduction to this system. If you are working or schooling or simply don’t have the time to sit down and play Forsaken World for a few hours straight and eventually get left behind in terms of character levels, this feature will certainly delight you. So how does it actually work?
For every period of time (hours, days) you are not in the game, a certain amount of EXP will be allocated to your character, like a compensation. Once you logged in, you will need to pay Soul Currency via a new window to buyout the EXP. The amount will depend on how much EXP you are buying out. And yes, you can accumulate this EXP, although there will be a max capacity before it stops. This EXP will not be affected by 2x EXP coupons etc.
So, how do players use this bonus EXP? As seen below, the bonus EXP will appear in the form of a green bar. This bonus EXP will be slowly used when players kill mobs, complete quests etc. For example, you are supposed to get 50 EXP after killing a rat. If you have purchased the bonus EXP, it will be used and you will get like 55 EXP (just an example, exact calculations not given). Once the bonus EXP is used up, the green bar will have been covered up by the blue bar (normal EXP). If you do want to know, the white words mean the amount of EXP needed to hit the next level.
