Cold Arrow converts a percentage of your physical damage to cold damage, around ({slvl × 2} + 1)%, then tacks additional cold damage on top of that. Like Fire Arrow, the elemental damage of Cold Arrow is based on the total physical damage of the bowazon after modifiers. (Refer to Fire Arrow for more information.)

A solid skill to have because it'll help your bowazon take out big uniques and bosses, mostly by slowing them down. Slowing an target is vital because it takes longer for them to close the gap between your bowazon and them; if they're ranged attackers, their attacks slow as well, which is when D/A/E skills kick in. For the first eighteen levels, count on using cold a lot to widen the gap between your bowazon and your targets.

If you're looking to raise the cold damage of Freezing Arrow yet don't want to raise the mana cost, consider this skill for its synergy.

On a further note, while the description for this skill says that cold arrows only do half their regular damage, this damage penalty was removed in v1.10.
