Columbina's main role is an off-field Sub-DPS and Lunar Reaction buffer. Her stats scale with HP, so reaching her HP threshold is a priority — aim for around 30,000 to 35,000 HP.

Since Lunar Reactions can CRIT, investing in CRIT stats is also important. For CRIT Rate, target somewhere between 60% and 80%, but avoid exceeding 85% as Columbina's passive already provides an additional 15% CRIT Rate. For CRIT DMG, aim for 200% or higher. As for Energy Recharge, around 150% should be sufficient to keep her Burst available every rotation.

Artifact Selection

Her best-in-slot artifact set depends on your team composition. If Columbina is the only Moonsign character on your team, Silken Moon's Serenade is the recommended choice, as it offers better team utility and energy management.

However, if your team includes other Moonsign characters such as Ineffa, Flins, or Lauma, Aubade of Morningstar and Moon becomes available and is generally considered her best-in-slot for maximizing personal off-field damage. Do keep in mind that this set requires her to remain off-field, so it's not ideal if you prefer to play her as an on-field unit.
