At higher levels, the time between levels can start to feel tiresome. The Skill EXP system divides each level into nine parts, and grants a small power increase as you complete each part, making progression smoother.
Leveling up is still a major event, though, so you’ll receive a bigger power boost than the other parts when finally reaching a new level
Experience penalties from death are also adjusted accordingly.
Items which revive you in place will also recover lost bonuses from Skill EXP
If you receive the death penalty because the character died, the level proficiency is also adjusted according to the EXP of after resurrection.
If you recover EXP with Friggs Healing Potion and such, the level proficiency is also recovered.
