Bleed Attack

Bleed Attack is a gem effect in Xenoblade Chronicles. It grants a percentage chance that the user's auto-attack will inflict bleed 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
Bleed 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). Compared to, Bleed Attack gems are individually stronger, but the total cap is significantly lower.

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