Some questions about Angelic Burster

Ahh, I forgot to include Hyper skills. Thanks!

Unfortunately, Nova class cannot get linked by other classes.

You can still receive the Character Card effects of other classes, however, so you can use a Marksman, or two, for the crit rate if you find it that important. You can get crit rate on like, every equip with additional potential, but a minuscule amount, like 2~3% max, I believe.
