Chill Attack

Chill Attack is a gem effect in Xenoblade Chronicles and Future Connected. It grants a percentage chance that the user's will inflict chill for 10 seconds, dealing extra  every 2 seconds (for a total of 5 extra hits). Unlike the debuff's normal effect, the damage done is equal to the gem's value, rather than based on the initial damage dealt.

Overview
Chill Attack is just an extra source of damage; it can be placed on anyone who wants to deal more damage without having to worry about extra aggro (as it's a debuff). Unfortunately, it is entirely outclassed by Blaze Attack, which does more damage at all ranks; as a result, there's very few situations where Chill Attack is the better choice.

In the original version, Chill Attack works against Mechon armour, dealing its full damage. In the Definitive Edition, it does not trigger at all.
