Research steps
Limit Bursts
Fill up a character’s limit gauge to unleash a
powerful attack called a Limit Burst.
This takes time, but with enough sheer force to
turn the tide of a battle, these attacks are worth
the wait.
Level 2 Limit Bursts
You have obtained a more powerful Limit Burst.
Level 2 Limit Bursts require a higher limit gauge fill,
but boast more powerful effects in return.
Characters who have learned a level 2 Limit Burst will
have two limit gauges, allowing them to charge up
to 200%.
