Grace of Letoile

During battles, the character icons are shown on the left-hand side of the screen, and next to them, a range of effects are sometimes displayed.
These are known as Field Effects, and if a character's turn comes while one of those effects is shown next to their icon, the character can gain the benefits of that effect.
However, Field Effects are not always advantageous. There are also disadvantageous effects. Also, effects apply to apply to both enemies and allies. However, by raising the level of the Chronos Gauge to 100% or more, you can launch Interrupt Actions. Whether an advantageous effect is attached to an enemy, or a disadvantageous one to an ally, you can use an Interrupt Action to change the order of the characters' actions, and avoid these unfavorable situations.

The Chronos Gauge is necessary for characters to be able to use the Particular Skills they each have, or to be able to launch Interrupt Actions, with which the order of the characters' actions can be changed. The Gauge has a display like a clock, with the numbers 1 to 12, and at the start of a battle one of the numbers will glow. The glowing number will move clockwise each time an ally or enemy performs an action. At this time, if you use a skill corresponding to the glowing number, a Just Time Bonus will be triggered, and the level of the Gauge will recover by a large amount. Also, the level of the Gauge increases, although only by a little, when enemies are defeated.
The Gauge is shared across all party members, so it's a good idea to pay attention to the level as you use Particular Skills and launch Interrupt Actions!

Somewhere in the world there is an Arena, where you can take part in challenge battles.
You can choose the course that best suits your level. You need to be victorious in each of three battles in order to clear the course.
The first time you clear each course, you will be rewarded with a rare item!
If you want a break while traveling around, or you want to check your abilities, pay a visit to the Arena!
