Ellesa

I wonder what this potion does?

Ellesa is the celestial of the forests. She guards the blue crystal and delves in the forests west of the Kingdom of Ussork as she harvests and experiments with the crystal's dust to manipulate fauna and flora all around Ussork which makes it a much more dangerous place than it looks.
Ellesa only makes an appearance to the people of Ussork when she's in the mood for it but other times, hermits within the woods south of the high castle from the main capital of Ussork where she vigilantly watches over the blue crystal.
Due to her exposure to the blue crystal's powder constantly, despite being a celestial, something is slowly changing within her but she refuses to acknowledge the unbridled rage boiling and building up within her as she carries on her duties. As such, the people of Ussork are cautious around her whenever they encounter her and thus, have a deep respect and appreciation for the fauna and flora within their kingdom.
Although Ellesa is the celestial of the forests, she boasts chaotic energy around her and as such, when sacrificed is given, she provides buffs to the Ussorks that increases their mobility, strength but sometimes send them into a berserker frenzy that causes them to attack each other.
