Overview:

S-Rank Light-element Osiris is a support with above-average strength. She can access most of her buffs right from the start of a battle. After her first Ultimate, her buffs are basically continuous, ensuring that all Light-element characters in the team are always fully buffed.

As a specialized support, she is completely qualified. At S-rank with a signature Functor, she can outperform most general supports in most situations. However, the Light element currently lacks a particularly strong main DPS, so Light Osi’s true strength cannot be fully realized. We are waiting for a future top-tier Light DPS.

As a DPS, her strength is not low, but SS-rank with signature Functor is recommended to play her as a DPS. Her strength is even higher at SSS-rank.


Sigil Recommendations:

  • S-Rank support:

    • Slots 1, 3, 5: [Ritual of the Reborn].
    • Slots 2, 4, 6: [Fountain of Youth].
      • This maximizes the buffs from her Aether Codes and signature Functor, but the downside is a loss of damage.
  • SS-Rank support:

    • Slots 1, 3, 5: [Ritual of the Reborn].
    • Slots 2, 4, 6: [Obelisk of Light].
      • This maximizes the main DPS’s damage, but the downside is a loss of Light Osi’s own damage. If a teammate can carry [Obelisk of Light], then the next set is recommended.
  • SS to SSS ranks:

    • Slots 1, 3, 5: [Ritual of the Reborn].

    • Slots 2, 4, 6: [Ambush of the Owl] or [Whole Truth].

      • The advantage is that it allows Light Osi to contribute more damage, suitable for players with good DPS enchants on her. If the enchants are not good or you don’t plan to invest much in them, it is recommended to use the dedicated support set.
  • Omega Support Sigils: Use

    • Slots 1, 5: [Ritual of the Reborn].
    • Slots 2, 3: [Whole Truth]/[Obelisk of Light]/[Vastness of Heaven].
    • Slots 4, 6: [Ambush of the Owl]/[Whole Truth].
  • DPS:

    • Slots 1, 3, 5: [Vastness of Heaven].

    • Slots 2, 4, 6: [Ambush of the Owl] or [Whole Truth].

      • Use [Ambush of the Owl] for Ultimate Skillchains, and [Whole Truth] for solo DPS.
  • Omega DPS Sigils: Use

    • Slots 1, 5: [Vastness of Heaven].

    • Slots 2, 3: [Whole Truth].

    • Slots 4, 6: [Ambush of the Owl].


Sigil Enchants:

For S and SS support, prioritize maxing out 8 [Standing Tall]. The required HP for support is 67,500.

At SS-rank with a transcend 1 Functor and level 100, you only need 7 [Standing Tall].

You can’t just look at the character’s panel HP, as that doesn’t include the bonuses from Aether Codes and the signature Functor. It’s better to check in battle.

The rest are DPS enchants. For DPS, since the signature Functor’s bonus also requires HP, but can only be maxed out at Omega with a transcend 5 Functor and level 100, low-investment builds generally don’t need that many [Standing Tall] as the improvement is not significant. Generally, 4 or 5 levels are enough. At SSS-rank, you can max it out. If you feel you are lacking ultimate energy, you can roll for 1-2 points of [Loopback].


Aether Code Recommendations:

  • Support: Use Blue 3 Aether Code.
  • DPS: Use Red 3 Aether Code.
  • Triple Osi: To support A-Rank Osiris + Ausar, it is recommended to play the Yellow line.

Warp Recommendations:

  • Support:

    • Slots 1 & 2: [Power UP: Melee] + [The Executioner] + [The Judge].

    • Slots 3 & 4: [EM Flux] + [Unfetter].

    • Slots 5 & 6: [Evolution Particle III] + [Armor Breaker] or one [Kinetic Mod].

  • DPS:

    • Slots 1 & 2: [Power UP: Melee] + [The Executioner] + [The Judge].

    • Slots 3 & 4: [Savage] + [Telepathize Forcefield I], can bring one [Unfetter] to increase initial Ultimate speed.

    • Slots 5 & 6: [Evolution Particle III] + [Armor Breaker] or one [Kinetic Mod].

      • With Skuld, you can bring [Current Decay].

Signature Functor (Pharaoh - Menes):

  • The signature Functor provides high base stats and an HP bonus, which is a huge improvement for her support capabilities. It is highly recommended to pull for it. The 2nd tier at SS-rank is more cost-effective than the 1st tier at S-rank, as it allows you to max out the buffs from her Aether Codes. However, the subsequent rank-up bonuses are not high, so it is not recommended to upgrade the Functor further for non-DPS builds.

DPS Rotation:

  • Startup: AAA/dodge - AA11 2 AAA111 2(AAA111 2) 3 loop

    • Use Ultimate when available.

    • See video guide for details.


Stat Boost Priority:

  • 3 > 1 > 2 > Normal Attack > Ultimate Skill
