Need help! Modding critical hits. Options

[omican]

1.Where is information about weapon critical threat is stored? For example, short sword has 19-20/x2, two-handed axe 20/x3, etc. I can't find it in .ITM files

2. In IWD2 there is Improved Critical feat. I'd like to modify it in way that charachters could take it several times. I found only few 2DA files, containing information about gaining feats on 1st and other levels by different classes. Nothing more about feats

How can i modify feat "mechanics"? Is it possible to modify feats using Near Infinity?

Yes, there are such items. I've found that such "sharp" items gives +1 to critical threat by replacing "normal attack type" by "keen attack type" in the item ability sheet. I don't know, is it possible to modify "keen attack" properties somehow.

I was thinking, that feat "Improved Criticals" works by replacing all attacks with keen attacks, but its cumulates with "sharp" weapons! For example, fighter with only this feat and normal axe has 19-20/x3, without feat and with sharp axe also has 19-20/x3, but with both feat and sharp axe has 18-20/x3.

How heavily feats mechanics is coded? I'm hoping to modify this feat somehow.
