Blaze Attack

Blaze Attack is a gem effect in Xenoblade Chronicles. It grants a percentage chance that the user's auto-attack will inflict for 10 seconds, dealing extra damage 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
Blaze Attack is just an extra source of damage; it can be placed on anyone who wants to deal more damage. As a debuff, it doesn't generate additional aggro, so there's no need to worry about that.

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