Unsure how to modify stats formula in database settings

I have been looking all over the internet and can't find anything on how to modify the formula of the stats and leveling up stats at all. I want to make chances to the way I want my server to be like. As it will be low rates, but I want characters to be more powerful then they normally would be.

To get more of an understanding here's a few examples.
I'll use the knight for the example.

When leveling up, the knight gets 2 Max HP and 0.5 Max MP... I want to change this to 4 HP and 1 MP.
also when leveling up, they gain an extra 5 atk rate, i want this to become 10.

Strength,
normally the knight gains 1 min dmg every 7 points, I want this to be 6, for max dmg it is 4 points, but that will remain the same.

Agility,
every 15 points you gain 1 atk speed, I want this to be 12 points instead


So, I think you get the idea? I want to modify every little detail with the stat points and level up.
If anyone knows how I can do this please help! :)

This should be on server side settings, so if your files doesn't support this options, you will have to use different server files or use OllyDbg and edit GS/GSCS manually.

what do you mean by side settings?
I have downloaded OllyDbg then opened gameserver but it is too mind boggling for me :(
I'm using 97d+99 if that helps.

I mean, if you don't have this configs in your config files, than you will have to search for related offsets in gs/gscs. But this is only for experienced developers, so better for you will be find server files with this configs.

I don't think I do, I've done a lot of searching with no luck and this kind of thing is too advanced for me unfortunately :(
