Genshin Impact Leak Report: Columbina Banner, Best Sandrone Support Builds, Eluga Details

 


Columbina Release, Sandrone Support Strategy & Eluga Overview — Leak Guide and Builds

The latest wave of leaks for the Luna IV update paints a noisy but fascinating picture: Columbina is poised to headline a banner with a unique mixture of burst-friendly mechanics and team utility; Sandrone, long theorized as a Fatui Harbinger rework or sibling, appears as a specialized support option rather than a main DPS; and Eluga emerges as a character with hybrid utility and niche combo potential. This guide dissects each leak, evaluates viability, proposes team comps and artifact/weapon choices, and gives a practical rollout plan for players deciding whether to pull or save.

Key short takeaways:

  • Columbina looks like a strong banner pick for burst and reaction teams if leaks hold true. Expect high-value synergy with Electro and Hydro setups.

  • Sandrone support appears designed to enable specific core DPS units (especially Hydro and Pyro) rather than carry herself. She’s useful for team S-Rank synergy choices.

  • Eluga seems to offer flexible utility with niche combos; not an auto-pull unless you need her kit for a specific team.

How I used research for this guide

This guide synthesizes recent community leaks and developer hints circulating around the Luna IV patch cycle as well as aggregated design patterns from previous Fatui/Harbinger releases. It integrates mechanics patterns from Hydro and Electro catalyst playstyles, support archetypes, and typical banners to project realistic builds and team roles for Columbina, Sandrone, and Eluga.

What to expect from leaks — reading them critically

Leaks vary in accuracy. Treat this guide as a reasoned projection: I use pattern recognition from previous patches, established balance directions, and plausible synergies to translate raw leak data into practical guidance. Always weigh your account needs and banner pity status before pulling.


Columbina — leak summary and role prediction

Leaked core points (reworded and synthesized):

  • Elemental type: Expected Electro/Hydro affinity interactions; often shown as a Hydro-catalyst user with a strong reaction focus.

  • Kit themes: Burst-scaling damage, field-control utility, and passive bonuses to allied reaction outputs. Her kit reportedly boosts teamwide damage when specific conditions are met (timed bursts or triggers).

  • Playstyle: Hybrid burst support who can also act as a sub-DPS; excels in enabling Electro-Charged or Overload chains and smoothing elemental rotations.

Predicted role: Flex sub-DPS / reaction enabler. Columbina appears to bridge reaction teams and catalyst-led AoE burst windows. She’s unlikely to be a pure sustained main DPS but will be extremely valuable where burst windows and reaction timing matter.

Columbina — kit breakdown (interpreted)

  • Normal Attack / Charged Attack: Standard catalyst animations; charged attack likely modifies field of effect or applies a persistent debuff to enemies.

  • Elemental Skill: Deploys a device or zone that alters elemental behavior in its radius (e.g., increases reaction damage, primes Hydro/Electro ticks). This is likely how she enables other units.

  • Elemental Burst: High-damage multi-tick AoE that scales off the number of reactions triggered while it’s active, rewarding coordinated play and elemental sequencing.

  • Passive(s): May grant a conditional buff to allies (attack or reaction damage) after the burst or skill triggers successfully.

Practical interpretation: Use Columbina to set up timed reaction windows—place skill, swap in Hydro/Electro DPS, trigger burst timing—and exploit burst multipliers.

Columbina — artifact and weapon recommendations

Priority stats:

  • Main stats: HP%/ATK% as the second main depending on whether scaling is reaction or flat damage, and Hydro DMG Bonus / Electro DMG Bonus if she is hybrid; Elemental Mastery if the kit multiplies reaction damage.

  • Substats: EM, Crit Rate, Crit DMG, Energy Recharge (if burst-hungry).

Top artifacts:

  • If reaction-emphasis and EM-scaling: Maiden Beloved + Instructor split or full Wanderer/Thundering Fury depending on exact scaling.

  • If burst damage scales from her personal stats: Nymph’s Dream-style set (Hydro catalyst synergy) or a catalyst-equivalent that increases burst damage.

Weapon choices:

  • High EM or Crit catalyst such as an EM-focused 5-star or a high-ER 4-star for rotation reliability. If she scales off raw burst multipliers, prefer high flat ATK or Crit catalysts.

Columbina — optimal teams and rotation examples

Team archetypes she suits:

  • Electro-Charged Burst: Columbina (support) + Hydro DPS (e.g., top Hydro damage unit) + Electro applicator (fast on-field) + utility (shield/healer).

  • Overload/Swirl Hybrid: Columbina sets zone, Pyro or Anemo comes in to amplify or spread damage.

  • Freeze/Burst pivot: If the skill primes Hydro application consistently, pair with Freeze drivers for control plus burst windows.

Sample rotation (Electro-Charged):

  1. Preload Columbina skill to stage zone.

  2. Swap to Hydro DPS; apply Hydro through quick attacks or skill.

  3. Swap to Electro applicator; trigger electro-charged interactions.

  4. Activate Columbina burst during reaction stack buildup for multiplied burst damage.

Sandrone — leak summary and role prediction

Leaked core points (interpreted):

  • Role: Support-focused rather than main DPS—her kit emphasizes buffs, debuffs, or interaction windows for a teammate.

  • Mechanics: Likely uses puppetry/construct mechanics (the Fatui Harbinger vibe), placing constructs that either absorb damage, apply periodic buffs to an ally, or manipulate enemy behavior.

  • Element: Possibly Cryo or Anemo adjacent mechanics given the Harbinger's past themes, but rumors suggest Hydro synergy with specialized support tools for catalysts and polearm DPS.

Predicted role: A niche but high-impact support that enables or amplifies one designated DPS rather than providing broad teamwide boosts.

Sandrone — kit breakdown (interpreted)

  • Elemental Skill: Deploys a 'puppet' or gadget that attaches to an allied character, applying buffs like increased damage, attack speed, or reaction potency. The puppet likely has a timed duration and scales with Sandrone’s EM or skill level.

  • Elemental Burst: Creates a larger field that enhances the targeted ally's damage while slightly impairing enemies (e.g., increased damage taken or reduced resistance).

  • Passive(s): Could reduce cooldowns of supported allies or convert part of damage into healing/shields, making her a sustain-support in longer fights.

Practical interpretation: Sandrone will be pulled for team compositions with a clear, single DPS carry that benefits from percentage buffs and rotation smoothing (e.g., main DPS who relies on reaction windows or large burst cycles). She is less valuable in broad-scaling teams without a fixed carry.

Sandrone — artifact and weapon suggestions

Priority stats:

  • Main stats: Energy Recharge to maintain puppet uptime; Elemental Mastery if buffs scale EM-based; HP%/DEF% only if passive scales off survivability.

  • Substats: ER, EM, Healing Bonus (if she provides sustain).

Top artifacts:

  • Nymph’s Dream or Emblem of Severed Fate could work if her burst scales with ER. Tenacity of the Millelith if she provides teamwide ATK buffs or shield support.

Weapon choices:

  • Support catalysts that provide ER or party-wide utility (4-star burst-augmentation catalysts). If her kit awards significant conditional damage, favor weapons that boost team damage indirectly.

Sandrone — best partners and team synergies

Ideal partners:

  • Single-target main DPS: characters who run long burst windows or require amplified burst (e.g., a Hydro or Pyro carry who benefits from consistent buff uptime).

  • Energy battery: a character that can quickly generate energy to ensure Sandrone’s puppets are always active.

  • Healer/shielder: to preserve the puppet’s uptime in high-damage encounters.

Rotation example:

  1. Activate Sandrone skill and attach puppet to the main DPS.

  2. Swap to DPS; execute normal DPS rotation.

  3. Use Sandrone burst during the DPS’s highest-damage window to capitalize on added buffs.

Eluga — leak summary and role prediction

Leaked core points (interpreted):

  • Element/Weapon: Descriptor hints at a generator/support with on-field persistence—potentially Dendro or Geo-adjacent, though leaks suggest Hydro/Geo hybrid utility.

  • Kit: Combines minor damage with buffs/debuffs, enabling combo setups rather than raw scaling. Eluga seems crafted for creative team-building rather than meta dominance.

Predicted role: Utility/sub-support — valuable for creative players who design niche synergies (e.g., buff stacking or enemy behavior manipulation) but not an essential pull for everyone.

Eluga — kit breakdown (interpreted)

  • Elemental Skill: Summons an object or applies a field that alters attack animation or grants a small DoT.

  • Elemental Burst: Grants partywide stat boosts for a short window and may interact with enemy resistances for temporary advantage.

  • Passive(s): Small scaling with party composition or with number of elements present.

Practical interpretation: Consider Eluga when building themed teams or when you need a small permanent utility slot (e.g., niche Spiral Abyss floors where her debuffs matter).

Eluga — artifacts and weapon choices

Priority stats:

  • Utility-focused stats like ER, EM, or HP% depending on passive scaling.

  • Substats emphasizing Energy Recharge and EM if her effects scale with reactions.

Top artifacts:

  • Nymph’s Dream for Hydro utility or mixed support sets that boost team buffs.

  • Scholar/Exile mixes if her role is more about uptime and utility.

Weapons:

  • Support catalysts that improve team stats or provide ER.


Comparative assessment — when to pull, when to save

  • Pull Columbina if: You run reaction teams, need a burst enabler, or have high pity and want a new flexible sub-DPS/support hybrid. She offers high-value utility in many compositions and could be a lasting meta pick.

  • Pull Sandrone if: You have a specific DPS who benefits from constant, targeted buffs and you enjoy optimizing single-DPS comps. She’s niche but powerful in the right setup.

  • Pull Eluga if: You’re a collector or you chase specific niche utility needs for Abyss floors or themed teams. Not recommended solely for meta reasons unless her kit aligns closely with your roster.

Budget strategy:

  1. Prioritize Columbina for broader impact.

  2. Consider Sandrone only if your roster has a DPS that receives meaningful benefit.

  3. Skip Eluga unless you enjoy collecting or need unique utility.

Banner timing, pity and value — practical advice

  • Banner timing: Leaks suggest alignment with the Luna IV cycle; expect a limited-time banner sequence similar to past updates. Prepare by checking your current pity levels and whether the banner overlaps with other targets.

  • Value assessment: Evaluate whether each character increases your team clear speed or content access. Columbina likely has the highest cross-account value; Sandrone and Eluga are more roster-dependent.

Saving tips:

  • If you plan multiple pulls, aim to secure Columbina early if she’s your priority.

  • Use soft-pity windows to stretch resources—wait for 50/75 pity where feasible.

Advanced build recipes and artifact stat pages

Columbina — advanced recipe:

  • Weapon: High-ER or EM catalyst (opt for Crit/EM balance).

  • Artifacts: 2-piece Thundering Fury + 2-piece Nymph’s Dream (if reaction-based) OR 4-piece hybrid set if you want single-target burst.

  • Substats priority: Crit Rate > Crit DMG > EM > ER (adjust to whether her kit favors EM).

Sandrone — advanced recipe:

  • Weapon: 4-star ER catalyst that smooths uptime.

  • Artifacts: 4-piece Tenacity of the Millelith (if she’s buffing ATK) or 2-piece ER + 2-piece EM if puppet scales with mastery.

  • Substats priority: ER > EM > HP (if puppet scales on survivability).

Eluga — advanced recipe:

  • Weapon: Support catalyst with ER or team utility.

  • Artifacts: 2-piece EM + 2-piece ER or full 4-piece support set if available.

  • Substats priority: ER > EM > Recharge.

Best domains and farm targets

  • Prioritize EM and ER substat rolls across all three characters if leaks about reaction scaling and burst uptime hold. Specific domain choices depend on regional artifact drops in the upcoming patch; target domains that drop catalyst-friendly sets and high-EM rolls.

Spiral Abyss and boss strategy notes

  • Use Columbina to coordinate timed reaction burst windows on floors with clustered mobs or when you need amplified AoE burst damage.

  • Sandrone shines on single-target bosses that benefit from long buff uptimes; use puppets to flatten DPS cycles and reduce the need for frequent swaps.

  • Eluga can be a niche counter to buffs/resistance mechanics—assess floors individually.

Playstyle tips and quick tricks

  • Stagger swaps intentionally: activate Columbina’s skill first, then layer elemental applications to maximize reaction stacks before bursting.

  • For Sandrone, always attach the puppet to the intended carry pre-fight; a misapplied puppet is lost uptime.

  • For Eluga, treat her as a slot-fill for specific mechanics: use her when your team lacks a required debuff or small stat bump.

Pull planner checklist

  • Confirm current pity and any featured reruns.

  • Calculate resource needs: how many pulls to reach 50/90 pity.

  • Decide priority: Columbina > Sandrone > Eluga, and set budget accordingly.

  • If you’re chasing a single unit, plan to stop once pity secures them unless you want duplicates for constellations.

Community reaction expectations and meta impact

If leaks are accurate:

  • Columbina will shape short-term meta by bumping reaction-based teams, particularly Hydro/Electro compositions.

  • Sandrone will spark creative single-DPS comps and niche team builds that leverage her puppet mechanics.

  • Eluga will provoke experimentation but likely remain off-meta for standard play.

Expect a spike in community theorycrafting: guides, rotation videos, and artifact templates will appear rapidly after the banner drops.

Frequently Asked Questions (FAQ)

What element is Columbina and is she a catalyst user?

Leaks point to Columbina functioning as a catalyst-like user who specializes in reaction windows; her element appears tied to Hydro/Electro interactions and she’s optimized for enabling Electro-Charged and similar chains.

Is Sandrone better as a support than a DPS?

Yes. Leaks strongly indicate Sandrone is intended as a support who attaches buffs or puppets to a primary DPS. She’s best paired with a single carry rather than expected to solo carry a team.

Should I pull on Columbina banner if I have a strong Hydro carry?

If your Hydro carry benefits from timed burst windows and reaction multipliers, yes—Columbina is likely to increase clear speed and burst potency for Hydro/Electro teams.

Is Eluga worth pulling for the long term?

Eluga seems niche. Pull her if you enjoy unique utilities or need a specific debuff. For meta-centric collectors, she’s lower priority compared to Columbina.

What artifacts should I focus on farming first for these characters?

Aim for artifact rolls that maximize Elemental Mastery and Energy Recharge for Columbina and Sandrone respectively. These two stats are the most consistently valuable given leak interpretations.

When will the banner likely drop?

Leaks are aligned with the Luna IV cycle; expect the banner to appear within the ensuing patch rotation. Exact timing requires official confirmation from the dev schedule.

How do I maximize value from a pity system when chasing these units?

Prioritize Columbina if you want broad utility. Set a resource cap for Sandrone and Eluga—they are more specialized. Consider saving for a guaranteed 5-star if you want to minimize risk.


Closing verdict and actionable next steps

  • If you want immediate, broad usefulness across content: prepare to pull for Columbina. She offers the most general team upgrading potential.

  • If you enjoy crafting tight single-DPS metas and have a favorite carry who benefits from targeted uptime buffs, Sandrone is a strong niche pick.

  • If you prioritize collection or niche content optimization, Eluga can be considered once you secure main targets.

Actionable to-dos:

  1. Check current pity and calculate pull budget.

  2. Farm artifact domains that give EM and ER ahead of the banner.

  3. Test potential team synergies in practice domains or Spiral Abyss when the banner hits.

  4. Track community builds after release and refine artifacts to match live kit numbers.
