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 IX). These are powerful skills that have a chance to appear every time you do an action or take damage. Each Special skill is unique to each class, and when used in a pinch, they could potentially save a failing fight into a winning one. When a Special skill is available, "Special/ひっさつ" will appear in blue at the top of your command menu.

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.
