Scriptable weapons? (maybe?!) Options

[pasco95]

I don't have PS:T but I read somewhere that Dakkon Zerths sword increased its damage with the characters level, is it possible to have hidden attributes on an item that only become available at a certain level such as increasing the magic resistance an item gives as you increase in level?
I have a tendancy to play paladins and therefore pretty much head straight to windspear hills, do the paladin stronghold quests, kick firkraags butt and grab Carsomyr, then it's an ass kicking spree from then on. This tends to make fights a little too easy though and I was wanting to limit Carsomyrs abilities to reflect your level, i.e. if you do what I do you're only about level 10 when you get Carsomyr and it's much too powerful that early in the game so I was wanting to, say, if you get it at level 10 it only does 1d10+3, doesn't dispel on hit and only gives 15% mr then when you hit lvl 15 say it does 1d10+5 can cast dispel magic 3 times/day and has 30% mr then at lvl20 it has its full abilities.
I know I went on a bit of a ramble then but I hope someone understands what I mean, is this possible?

Can you even script an item? I've got no idea but if this is possible I think it would be a nice tweak so that Carsomyr's still an awesome sword but you aren't hell bent on trying to get it ASAP so you can be a major tank.
Thanks in advance for any help.

You can add script to the game to replace different versions of the item with each other depending on your xp. You need to make as many versions of the Carsomyr sword as you wish (with different abilities) to be replaced with each other automatically via script.

Or you can add script to the game to summon a divine being each time your paladin hits a certain level to ask him whether he wants to replace the sword with its next version or he prefers some other bonus (or anything like that).

The script, however, won't belong to the weapon. The scripting blocks should be added to BALDUR.BCS and BALDUR25.BCS.
