Jahoda is an Anemo sub DPS/support character who provides Swirls, periodic elemental application for the absorbed element, healing from Burst that scales with ATK, and minor EM buff to the active healed teammate from her talent.
She is also a Moonsign character who can increase the team's Moonsign level by 1, useful to pair with other Moonsign characters to activate Ascendant Gleam.
