Act Bosses, Super Unique monsters, Champion monsters, and other players cannot be frozen; they will, instead, be Chilled.
Chance of freeze / chill is ( 50 + (AttackerLevel + (B*4) - DefenderLevel) * 5 )%
B = item bonus (usually is 1). If you use freezing in ranged attack, then AL is decreasing by 6 and chance divides by 3. Duration = (chance - roll) * 2 + 25 frames, Durability ranges from 25 frames (1 second) to maximum of 250 frames (10 seconds).
