Mistique (Minion) ✏️

Cosette

Among the current options for Umbra, Cosette is the best Trekker to placed in the Main Slot for this team. Her only purpose is to provide Umbra-related buffs for Mistique's minions. Due to how peculiar minions are on buff interactions, there are barely any potentials that can reliably be used for this team.

★ Key Notes:
• Only use Cosette's Main Skill within the AA1-AA3 attack sequence to prevent Twilight Wish stacks from expiring.
• Netherworld Touch enables the Umbra DMG taken debuff from Nocturn Mark to have a permanent uptime.
• 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

Priority

Netherworld Touch

After casting Nocturn Hooks (Main Skill), Cosette's Auto Attack is enhanced for 8s, increasing its Attack Range, Auto Attack DMG by 60%, and Attack Speed by 35%. Her Auto Attack can also inflict Umbra Mark: Gloom.

Nocturn Mark

When Cosette inflicts Umbra Mark: Gloom on the same target for the 3rd time, leaves claw marks, dealing 39.3% of ATK as AoE Umbra Skill DMG, increasing the target's Umbra DMG Taken by 32% for 3s, and inflicting Umbra Mark: Gloom. This effect can only be triggered once per second.

When dodging, increases her Attack Speed by 11% for 3s.

Emblem

Mistique

Contrary to other team compositions, Mistique's DPS capability shines when placed in the Support slot. With the combination of The Conjuring and Twin Born potentials, she is able to spawn a sheer amount of minions that deal high amounts of AoE damage.

★ Key Notes:
• Make sure to group up enemies in order to take full advantage of her minions' small range explosions.
• Try to keep enemies within Mistique's circle to benefit from Solar Absorption's debuff.

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

Iris

Iris provides a powerful crowd control effect and high ATK% buffs that Mistique's minions can freely benefit from. Her wide-range Support Skill can pull and lock enemies in place while buffing allied units within its zone. If you have Frozen Shield, her Ultimate will also buff allied units within its vicinity.

★ Key Notes:
• Sneaky Fisher and Prolonged Winter are all you need to make her work for this team composition.
• Despite the fact that Frozen Shield says squadmate on its tooltip, it has been tested and proven that it does work for Mistique's minions.
• Only take Charge Efficiency on her emblems if you have Frozen Shield in your Record.

Skill

1/1/1/1 (Not needed)

Iris is only used for her crowd control capability and buffs from potentials. None of her skills scale buffs or debuffs so there is no need to waste resources on her.

Emblem

Coronis

Coronis is potent against boss fights due to her ability to provide constant Resilience shred with Medical Research.

★ Key Notes:
• Medical Research is the primary reason why Coronis is taken for the team. If your Record does not have it, don't expect her to do much.
• 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.

Emblem

Chixia

Chixia provides a higher ATK% buff ceiling but lesser uptime than Iris, with the additional benefit of providing Crit Rate for Mistique's minions. Keep in mind that majority of her buffs require build-up for maximum effect as she has to summon her dragons gradually.

★ Key Notes:
• Crimson Dragon: Convergence enables Ink Sigil: Horn Call and Ink Sigil: Barrier Construct to provide more buffs.
• Crimson Dragon: Chant allows the uptime of Ink Sigil: Ambush to be more consistent.
• Make sure that Mistique's minions explode within the circle of the Crimson Dragons so they can benefit from the Crit Rate buff.

Skill

1/1/1/1 (Not needed)

Chixia is used for her valuable Potential kit as none of her usable skills scale buffs or debuffs so there is no need to waste skill upgrades on her.

Potential

Priority

Rotation

The goal is to buff Mistique's minions as they are being summoned out of her circle.

General Rotation

With Mistique's Support Skill pre-casting
1. Mistique Supp. Skill
2. Wait until Mistique's Supp. Skill CD reaches 5s
3. Iris Supp. Skill + Cosette Supp. Skill
4. Mistique Supp. Skill
5. Iris Supp. Skill + Cosette Supp. Skill
*Then repeat Step 4 and 5

Without Mistique's Support Skill pre-casting
1. Mistique Supp. Skill
2. Iris Supp. Skill
3. Cosette Supp. Skill

Cosette/Mistique/Coronis
1. Mistique Supp. Skill
2. Cosette Supp. Skill + Coronis Supp Skill

When to use Ultimate?

• Cosette (w/ Nether Blaze): Before using her skill.
• Mistique: Whenever available as long as her skill is not cancelled.
• Iris: When Supp. Skill has 10s CD left to prevent delays.
• Coronis: Preferably when the enemy has resilience bar active.

Tips

• Try to line up Cosette's Main Skill with Iris' Supp. Skill.
• If you are using Coronis, be mindful about the boss locking their Resilience bar since she will not be able to deplete it if it's locked.
