It's for the Steam version, no?
But I could pinpoint the value to four addresses that you have to change at the same time. Works like a charm. Just reloaded after the successful cheat, finding out how it can be made to work is more interesting than playing with the better Crafting.

For everyone who also cannot get the GoG-version to run with the tables or in case a new patch comes out that invalidates the cheat:
You will need more than one Ability Point to spend (3 or 4 works good, but it probably also works with 2).
I. Save your game.
II. Open the game's process in Cheat Engine and search for your current free points. Change the value in the game and APPROVE the change with the green marker (you need to do that). Like buy a point in something you do not need.
III. Scan for that new value in cheat engine.
IV. Go back to the game, move the party a bit, move the screen a bit. Then just do a new scan with the same value like the last scan. That will eliminiate a lot of Values that fit simply by chance.
V. Buy another point in the game, approve, scan for the new Value in Cheat Engine. Repeat until you have no more points to spend. Sometimes it helps if you do IV. again, until no more values can be eliminated.
You should have four addresses, all showing the same value.
VI. Change all four values to whatever points you want in CE.
V. Go back into the game, close all menus, open them up again and you will see your new points to spend.
As this process finds the absolute addresses and not pointers, you'll have to redo this each time you reload. But it works and you might not do it often. This should also work with all kinds of other fields you might want to play with. This is somewhat crude, but quickly done and effective.
