Need a level skript! (cause idk how to do)

[Rylen]

i need a level skript for my server which is currently in beta and it is a sky mining server, i will put your credits somewhere where its easy to find. pls send it to me on discord if you get or make one  Rylen#4866

Idea: (make a function)

when you level up it gets harder to level up. (dividing) (on mine)

 

Extras :3 :
Level up message ("

LEVEL UP! [%level_variable%]
(+10000), 

")

(+10000) = amount of coins they get,
coins variable: {dragonstats::coins::%player's uuid%}

anyways if you can do i thanxs you very mooch.
