[Help] WHICH TABLE?

I have four tables, levexp, levexp_0, levexp_1, and levexp_x.
One of them doesnt contain the same tables as the other three, that one being levexp_x.
What I am trying to do is make it harder to level.
I have made adjustments to the column usruplevexp in levexp. I have tried it with high and low numbers, the same and different. When i restart the server, the levelling becomes stupid- Kill 3 madbulls and go up an amazing 97 levels in total.

I have noticed that all three tables, (0, 1 and x) do not have identical entires in the columns they all share.
I hope i am making sense so far?

My questions are-
1- What columns do i need to adjust in order to reduce the levelling?
2- Higher or lower numbers?
3- Do all three/four tables have to be edited to read the same?
4- Am i looking in the wrong place?


ADDITIONAL
CQ_LEVEXP AND REDUCE PERATK.
Thats what i just did and it works. Where the entry was 4 digits, I removed the last one.

First you'll have to check where the actual experience is being received. Check wether its in the monstertype. Like does it have additional experience per kill? Is it attached to an action that awards experience? If its none of those then you can resort to the actual experience table.
