Charged Attack
Performs a more precise Aimed Shot with increased DMG.
While aiming, the power of Hydro will continually accumulate on the arrow. After fully charging, Sigewinne will periodically fire slow-moving Mini-Stration Bubbles toward the target, dealingHydro DMG. When released, an arrow imbued with torrential energy will dealHydro DMG to the opponent hit.

Plunging Attack
Fires off a shower of arrows in mid-air before falling and striking the ground, dealing AoE DMG upon impact.

Blows aBolstering Bubblebalm that can stimulate blood flow and help patients drift off to sleep using a bubblegun specially made in the Fortress of Meropide.
Bolstering Bubblebalms will bounce between nearby opponents, dealingHydro DMG based on Sigewinne's max HP to opponents it hits. When it bounces, it willrestore HP to all nearby party members except Sigewinne herself. The amount healed is based on Sigewinne's max HP.
After bouncing 5 times, the Bolstering Bubblebalm will disappear and restore HP to Sigewinne based on her max HP value.
When no opponents are present, the Bolstering Bubblebalm will bounce nearby. Only one Bolstering Bubblebalm created by a Sigewinne may exist at once.
When Held, the Bolstering Bubblebalm can be boosted to an even bigger size.

Hold
Enter Aiming Mode to begin blowing an even bigger, even more breathtaking Bolstering Bubblebalm!
The Bolstering Bubblebalm will grow bigger the longer the skill is Held, until it grows up to two tiers in size. Each tier it grows increases its DMG by 5% and healing by 5%. When a Bolstering Bubblebalm bounces, it will drop down a tier in size, until it returns to being a normal Bolstering Bubblebalm.
After weaker opponents are hit by big Bolstering Bubblebalms, they will be imprisoned and will be unable to move.

In addition, 2Sourcewater Droplets will be created near Sigewinne when she uses this Skill. Each Sourcewater Droplet Sigewinne collects will grant her aBond of Life worth 10% of her Max HP.
