The very manifestation of that peaceful foreboding feeling before a huge storm hits the coast. She may be cute and somewhat innocent, but don’t underestimate the power that’s building up behind her.
The Calm Before The Storm is interesting for the fact that he power grows over time. The longer she goes without attacking the more powerful her next attack will be. In this way she ends up being a great late game sweeper coming in behind her allies and wiping out anything left that may have survived. She’s also great for causing chaos with her Debilitating Mist ability which blinds enemies in the area it affects.
Just like a real storm she brings forth destruction and confusion everywhere all with a cute little smile on her face.
