I'm still not convinced, to say the least...
I only count 7-8 bolts on that CBS. It could just be a low lvl trap that's easily negated with absorb. What was the Sorc wearing in both the "with" and "without" videos? What was the damage on the trap in both the "with" and "without" vidoes?
Regarding the Guided Arrow video, I see no significant difference in the amount of damage she takes between the "with" and "without" segments. The arrows occasionally miss in both, so what exactly are you proving? Guided may be ITD, but it still goes through the chance to hit formula, which depends on clvl. What lvl is the Sorc? What lvl is the Zon?
The last two segments are essentially meaningless. Blade Fury goes through the chance to hit formula, so obviously you're going to take less damage with Chilling Armor activated (higher defense). With Orb, you did the first segment with random casts from relatively far away, then you move up into (nearly) the optimal Orb position for the "without" segment, which is just misleading because it does so much more damage from there.
I'm not cynical just for the sake of disagreement. I just find it hard to believe that the cold armors work like that and nobody has documented it.
