Emblem

Cosette

Cosette is the staple support for any Umbra team at the moment due to the consistent high Umbra DMG Taken debuff and ATK% buffs that she is able to provide.

★ Key Notes:
• Phantom Mark is preferred over Abyssal Mark as it allows Cosette to be on field longer.
• Dark: Mirage is a very good potential to take as the 4th option if used against a single enemy. If used on multiple enemies, it will negatively affect Dark: Afterglow and Dark: Demon Mark's uptime.
• Charge Efficiency from her emblem is only relevant if you have Nether Blaze on your Record.

Skill

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

Abyssal Hunter (Support Skill) is the only skill that matters here as it scales the Umbra DMG Taken debuff inflicted based on the level of the skill.

Emblem

Otoha - Laser Build

Otoha's laser build pales in comparison with her skill build when it comes to providing buffs and debuffs. However, what it brings is the ability to be used against bosses that are mobile.

★ Key Notes:
• Solitary Lantern, along with Night-Walker, are the main potentials that enable her to do damage.
• Having a +1 level of Solitary Lantern on your emblem is a big priority for this build as its Ultimate Crit Rate buff gets doubled at Lv 7.
• Devouring Shadow provides a unique DEF PEN buff that requires Otoha to be in an all-Umbra team to work.
• Ensure that her Support Skill is on cooldown before using her Ultimate to take advantage of the buff from Without A Trace.
• Hollow Steps synergizes with Night-Walker and Solitary Lantern as it consistently increase her personal Ultimate Crit Rate and Crit DMG.

Otoha - Weeping Sky Build

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.
