More on the Break/Toppled/Dazed System. Once an enemy is Toppled/Dazed they are knocked down and can no longer attack. Unless Toppled/Dazed again, they will only be down for a few seconds. It is possible to stack/chain Topple and Daze attacks to increase the length of the down status. There are certain gems that boost Break/Topple/ Daze effects which can increase activation rates and the damage done while using the system.
In the image, the green arrow in a circle represents the Topple status. Break is represented by two squiggly pink lines that can also be seen in the image and Daze is represented by a yellow star. Break makes the enemy vulnerable to the system, Topple knocks the enemy down, and Daze keeps the enemy down longer. It may sound confusing but you'll get it after a bit of practice.
