Just bear in mind that Freezes Target doesn't always Freeze the target. IIRC, Iceblink has Freezes Target + 1 meaning that if MLvl =< CLvl + 1, then you CAN freeze them otherwise you will NEVER freeze them (only chill). Even if you CAN freeze them, I think there's still a chance you will only chill them.
Still, doesn't stop it from being an excellent armour, though somewhat lacking in resists..
Also, Cold damage from charms and items might add to the freeze duration, but don't quote me on that one.
