-----

The core script's experience calculation formula reduces the increase in
required experience points as the level increases,
making it easier to gain levels from the mid-game onwards.
This plugin modifies the experience calculation formula so that the increase
in required experience points is less gradual even from the mid-game onwards.
With a base value of 30, a modifier of 20, growth rate A of 30, and growth
rate B of 30, the required experience points at level 50 are 34,886 and the
total experience points are 597,700.
At level 98, the required experience points are 134,401 and the total
experience points are 4,451,685.

@plugindesc 経験値計算式変更
@author NUUN
@version 1.0.0

@help
コアスクリプトの経験値計算式はレベルが高くなるほど必要経験値の上がり方が緩くなるため、
中盤以降レベルが上がりやすくなってしまいます。
このプラグインでは経験値計算式の仕様を変え中盤以降でも必要経験値の上がり方を緩やかにならないように変更します。
基本値３０、補正値２０、増加度A３０、増加度B３０でレベル５０での必要経験値は34886、累計経験値は597700、
レベル９８での必要経験値は134401、累計経験値は4451685です。

利用規約
