half freeze duration

[Ruvanal]

As Jarulf noted the freeze/chill durations are adjusted by the flag of item_halffreezeduration (duration/2) and then an adjustment by the resistance rating of the target (note this is done only with freeze/chill, not with poison durations). In LavCat's case, assuming that the base chill duration is 2 seconds (50 Frames), the half-freeze duraation would cut this to 25 frames and a 90% resitance would further reduce this to (25*(1-.9)=) 2 frames (0.08 seconds) or "just an instant" as LavCat puts it. Compare this to effect of cannot be frozen where the character will not even turn blue for what the apparent difference would be.

I'm not the code-cracker typus, but isn't there an entry of its own I think in monstats.txt which defines how intensely monsters are affected by chilling? By example the Frenzytaurs in the Worldstone Keep, they have no resistance to cold at all, but they are hardly freezeable, and at the Throne Room they aren't freezeable at all.

Yes there are such entries in the monsters.txt files, but it is for how much of an action rate slow down they will be effected by from the chilling effect; not the duration itself.

In this case the main question was concerning the effect on a character who is not listed there.
