Costs to raise skill and stat levels

The costs for raising primary stats will always be a constant similar to this scale, but this cost scale for raising skills is based on a single class player only. If you are a multiclass player, the normal change will apply:
If you are 2 classes, 3 times the exp
If you are 3 classes, 4 times the exp
If you are all 4 classes, 6 times the exp
