With Polar Star:
SUPPORT
A Bow user providing off-field Dendro application and supplementary damage.
Weapon Choices
Polar Star maximizes personal damage, but Elegy for the End’s teamwide buff typically yields greater value. Sacrificial Bow requires at least Refinement 4 to be effective.
Artifact Sets
Tenacity of the Millelith (4): Sprout counts as Skill damage, letting the set’s buff persist through key damage windows. An alternative to Noblesse Oblige (4) or Deepwood Memories (4) when both are already in the team.
Gilded Dreams (4): Only used in teams where she triggers reactions, such as Bloom or Burning.
