Coup de Grâce

Coup de Grâce is a special battle ability in Dragon Quest IX. Each vocation has a different Coup de Grâce with different effects. The ability becomes available during battle randomly when certain conditions are met. When a character is able to use a Coup de Grâce, a notification is given saying:

[party member] is primed to perform a coup de grâce!

The effects of Coup de Grâce last for only a short period of time. They do not carry over after the battle ends, or if the character dies. If all four party members are primed for a Coup de Grâce, they can together perform a Co-op de Grâce.

List of Coup de Grâce by vocation

Name	Vocation	Effects
Critical Claim	Warrior	This coup de grâce unleashes an attack that always inflicts a Critical Hit.
Roaring Tirade	Martial Artist	Similar to War Cry, except it cannot be resisted. Further, it also increases tension by one level.
Choir of Angels	Priest	Restores 30%~40% of Max HP to allies and cures status effects at once
Rough 'n Tumble	Minstrel	Evasion increases to 50% and the ability to counterattack goes to 25%.
0 Zone	Mage	Reduces MP cost to zero for a short while.
Itemized Kill	Thief	Guaranteed item drop from the enemy it is used on.
Knight Watch	Paladin	Attacks will do nothing for a few turns on the person who used it (not even Disruptive Wave can get through). All of the opponents are enraged to the person who used it.
Brownie Boost	Ranger	Boosts the user's attack, defense, and breath resistance by one level.
Tension Boost	Gladiator	Boosts tension up to 50 or 100 (maximum).

List of Co-op de Grâces

If all four party members are primed for a Coup de Grâce, then upon using them they will perform a Co-op de Grâce, selected from a menu.

Omnipotense	Martial Artist Gladiator	Increases all party members' tension by 3 levels.
Soul Asylum	Priest Paladin	Renders the entire party invincible for a few turns (similar to Knight's Watch).
Cast Away	Mage Sage	Reduces the party's MP cost to zero for a few turns.
Haulellujah	Armamentalist Thief	Chance to earn extra exp., gold, and items. Exp and gold multiplier is 1.5~3.0
