Otoha (Weeping Sky) ✏️

Cosette

Cosette occupies this team's Main slot as she is able to provide high amounts of Umbra DMG Taken debuffs through her potentials and Main Skill.

★ Key Notes:
• If you can, use Cosette's Main Skill within the AA1-AA3 attack sequence to prevent Twilight Wish stacks from expiring.
• You can take Nightshadow Veil to maintain the Umbra DMG buff gained from Those With Ambition's Harmony Skill or to simply have better survivability.

Skill

1/10/1/1 (Main Skill only)

Nocturn Hooks (Main Skill) is the only skill that you should upgrade since it scales the amount of Umbra DMG Taken debuff based on its level.

Potential

This effect can only be triggered 5 times per Skill cast.

Emblem

Otoha

Otoha's skill build relies on the synergy of Ripple of Shadow, Evening Rain, and Rain-Woven Sorrow to bombard a specific area with Sweeping Sky. This works best against enemies who are gathered in one place and bosses that are not mobile.

★ Key Notes:
• Make sure that enemies are within the bombardment area of Sweeping Sky as this is the only way she can deal damage on this build.
• Devouring Shadow provides a unique DEF PEN buff that requires Otoha to be in an all-Umbra team to work.

Skill

1/1/10/1 (Support Skill only)

Shattered Edge (Support Skill) is the only skill to prioritize for Otoha since both Ripple of Shadow and Evening Rain's DMG scales based on this skill's level.

Potential

Priority

Emblem

Mistique

Mistique acts as a sub-DPS and debuffer for the team using her typical minion build plus Solar Absorption.

★ Key Notes:
• If you need crowd control more than her damage output, replace Happy Face and Reality Erosion with Slumber Invitation and Lucky Constitution.

Skill

1/1/10/1 (Support Skill only)

Summoning Circle (Support Skill) is where all of Mistique's DPS comes from. The Minion DMG dealt by her summoned minions scales based on this skill's level.

Emblem

Coronis

If you do not have Mistique, Coronis is the final alternative to take her place. Her role for the team is to provide ATK% and Umbra DMG Taken debuffs and help with depleting enemy Resilience with her Medical Research potential.

★ Key Notes:
• The 5% resilience depletion from Medical Research does not increase further with higher levels.

Skill

1/1/1/1 (Not needed)

Coronis is only used for her Potential kit and none of her skills scale buffs or debuffs so there is no need to waste resources on her.
