Stagger

Stagger is a in Xenoblade Chronicles X. It is roughly equivalent to Break from other games in the series.

Overview
When a player or enemy is Staggered, they are knocked back, interrupting any actions they would otherwise be taking. Additionally, this status reduces resistance, although it isn't necessary to use Stagger to topple anyone. Instead, it's necessary to inflict Stagger in order for a Skell to inflict on a large enemy.

Levels
There are 5 levels of Stagger, from Stagger I to Stagger V. Each successive level increases the duration of the Stagger debuff.
