Calculates exp with level difference

[mehdy11]

Hello, I want find the function to calcule the exp with the level difference.
I made some test on the dander lvl 1 (base exp is 180) and the exp change when the level difference is > 5.

One table :

But the exp of Reborn Devil (lvl 75 in LoD) is 40000 and on a level 92 I win 4729 when I kill one and it is far from my function found with this table.
All your ideas are well come.

Sorry if I explain wrong.
