You may check attribute price on this site (select your class first):
https://tos.neet.tv/attributes?cls=Char3_16&f=1
Example:
dont ask how can i make this,my hands is killing me 
THANK YOU MAN!
I made a fool of myself
Also the cost increse by 7% each lv (From the previous lv)
But yeah … Just use the attribut calculator … Way faster/easier !
Does that calculator have the correct prices? Because IMC apparently secretly reduced the prices with the last patch.
Just multiply to 0.8 and it’s preety accurate.
It’s important to note that the cumulative price of each attribute pretty much doubles every 10 points
ie: if your multi shot cost you 5m to be lvled from 0 to 90, it’ll cost around 10m to go from 90 to 100
So don’t focus on only one attribute
