Moderate Expand mp problem

My player is LV139 Corsair and my clear int is 60,and added buff and int eq my int is 142
When I level up,I clicked mp props for expand my mp value.
My mp value only expand 17 and 18(clicked 2 times).

I not actully know the data about expand mp.
if use clear int count:
It should be at least expand 16+(60*0.1)int mp

if use buff and eq int count
It should be at least expand 16+(142*0.1)int mp

Why my mp only expand 17 or 18

 

Equipping int gear only allow u to gain more mp when u level up, only base int helps in ‘mp wash’.

It just work this way, not a bug.

 

My base int is 60
Why my mp wash value is 17 not 22
16+(60*0.1)=22mp

 

If u put fresh ap into hp/mp there is always a slight variation. I believe it should be somewhere around 12+6 instead of 16+6.

 

Buccs and sairs gain less mp out of mp washing if i remember correctly, they gain mp like the mp from level up but -5. All other classes lose on 1 mp compared to their lvl up
