Lunar Vow

Lunar Vow (LV) is given a Stellar Key weapon in v8.7. With the Stellar Key, she’s protected by Astral Ring.

Traits

Bleed = LV almost constantly deals bleed trauma while attacking. She deals *neither melee nor ranged DMG.

Fast ATK = LV attacks are among the fastest, her ultimate, Stellar Shift, and SO closer deal huge amount of hitcount shields despite stopping timer.

Symbiosis = LV can support other Grail of Infinitude valkyries like Helia PAWS.

During Stellar Outburst, she provides extra SP by using special attacks and ultimate.

Heavenly Shift = LV can support Law of Ascension valkyries like Badum Kiana (FWS).

During Stellar Outburst, she performs a special ATK animation whenever her avatar flashes purple and clicked

Affix

Best for LV:

6 ATK affixes of either:

  1. PSY type or;
  2. Blade, Cross, and Chained Blades
    ⚠️ Critical and Elemental Characters
    Elemental character do NOT deal critical damage.

Best and Worst Use Cases

LV is best used against:

  1. MECH bosses
  2. Bosses that are weak to Lightning and Bleed damage
  3. Bosses with Grail and LoA up weathers if they’re not BIO type
  4. Bosses with high . She is also benefitted from some fast ATK related buffs in ER.
⚠️ AR Specialization Weathers
Having correct AR Attributes help in AR Specialization Weathers. LV, even as leader, could be buffed in LoA up weather by 10% because of her AR Attributes. Having team members with Heavenly Shift buffs further more.

AVOID using LV against:

  1. BIO bosses
  2. Bosses that are resistant/immune to Lightning damage
  3. Bosses with Physical weather

Teams

Lunar Vow (LV) is a valkyrie, so she has to be supported by AR valkyries with Symbiosis trait, otherwise her potentials aren’t fully unlocked. However, using Rite of Oblivion valkyries CAN work until you get Symbiosis valkyries, as they provide general buffs.

As a support, LV can support Grail of Infinitude and valkyries.

Infograph

If you’re having hard time reading the infograph below,

Support Capability

Lunar Vow (LV) is overall a strong Grail and Law of Ascension support, but is particularly good support for AR valkyries, so she’s especially strong Planar Armament: Warped Spacetime (PAWS) support thanks to bonus elemental damage buff for Lightning valkyries.

If you’re having hard time reading the infograph below,

As dps, Lunar Vow (LV) activates her ultimate with high cost so she can start slashing enemies with multiple weapon skills. This is retained in her Stellar Outburst state, the difference is that each slash costs Shining Trace/shared team SP. Being a fast valkyrie, her ultimate, SO Closer, and Stellar Shift all shred hitcount shields in humongous amount despite all three stops time, thus directly competing with Peregrine Sword in terms of hitcount shields shred.
