Intelligence can now reduce or increase monster point generation in 50%.

Well, it'll never increase in 50% because for that you need Lv 1 and 150 int.
That's impossible as bonus int (e.g. equips and job) aren't counted for this.

However, getting a -50% penalty is perfectly possible if you have 1 int at lv 200.
