Seira's Strengths & How to Use

Excellent speed-related effects

Seira has excellent speed-related effects, including the aforementioned Action Gauge increase, and is also excellent at giving speed debuffs to enemies.

It is a powerful move that indirectly contributes to increasing the number of moves for allies, increases the number of actions with your own speed buff, and pulls up allies with special skills, so you want to be conscious of increasing your speed as much as possible.

Be careful of auto behavior

When using Seira in automatic operation, be careful about the target of Special Skill. I'm grateful that Special Skills are prioritized over Ultimate Skills, but the targets of the skills are random, so sometimes the battle doesn't go as planned.

If the difference in strength is marginal, targeting the wrong target with a skill can be fatal, so if you use Seira, you should fight manually.
