Special and Chance Skills

Special/Coup de Grace Skills
After completing a vocation's 4th vocation quest, you will unlock that vocation's Special Skill (known as Coup de Grace in Dragon Quest IX). These are powerful skills that have a chance to appear every time you execute an action or take damage. Each Special skill is unique to each class, and when used in a pinch, could potentially turn the tide of battle. When a Special skill is available, "Special/ひっさつ" will appear in blue at the top of your command menu for a short time.

In addition, after completing a certain quest in version 3, you will unlock each vocation's second Special skill. Once unlocked, you are able to use both the first and second Special skills before the command will disappear. However, some of the second Special skills have a charge time.

Chance Skills
After completing a certain quest during version 3, you will unlock the ability to use Chance skills. These will randomly trigger during battle much like Special/Coup de Grace skills, but every vocation is able to use every Chance skill. After a Chance skill is used during battle, it will take some time to recharge before it can be used again in the same battle. When a Chance skill becomes available, "Chance/チャンス" will appear in pink at the top of your command menu.

Triggering Chance Skills
Depending on the type of action that occurs in battle, there is a certain percent chance that your Chance command will become available.

The chance to trigger a Chance command off of an ally's Chance command trigger is called a Chance Chain (チャンス連鎖).
