When Dahlia debuted in version 4.X, she immediately shifted Genshin Impact’s support meta. This four-star Hydro sword wielder offers massive HP-scaled shields, a partywide attack-speed buff, and a unique “Mystery Mist” Hydro field that both damages foes and propels allies for aerial combos. In a game where Freeze and Vaporize comps battle the clock in the Spiral Abyss, Dahlia’s toolkit feels like a true paradigm shift. Read on for clear breakdowns of her skills, builds, team setups, and matchup advice.
1. Core Abilities
1.1 Elemental Skill – Psautier Radieux
Psautier Radieux conjures a protective barrier around Dahlia and nearby teammates. The shield scales with her Max HP and grants a brief party attack-speed boost when it lands. Its uptime hinges on cooldown management and Energy support, making Energy Recharge and reaction synergies critical.
1.2 Elemental Burst – Mystery Mist
Mystery Mist consumes Energy to create a Hydro zone that persists for a set duration. Enemies inside sustain continuous Hydro damage based on Dahlia’s HP, while allies are lofted every few seconds—ideal for chaining plunging and aerial hits in high-combo lineups.
1.3 Passive Talents
- Graceful Current: Increases movement speed during daytime when Dahlia’s shield is active, aiding exploration and kiting.
- Sacrament Accumulation: Grants reduced cooldowns and Energy restoration when triggering Freeze reactions, enhancing uptime in reaction-focused comps.
2. Constellations
Dahlia’s early constellations yield immediate benefits, while higher ones unlock niche utilities for dedicated players.
- C1 – Aquatic Preservation: Shields generate bonus Energy.
- C2 – Diversionary Veil: Boosts shield absorption.
- C4 – Fluid Momentum: Strengthens the partywide attack-speed buff.
- C6 – Sanctuary Restored: Provides an emergency full revive and team buff on a long cooldown.
3. Artifacts & Stat Priorities
Dahlia thrives on high HP for shield potency, but balancing Energy Recharge and Elemental Mastery ensures consistent uptime and reaction support.
3.1 Main Stats
- Sands: HP% or Energy Recharge, depending on your current ER total.
- Goblet: HP% for pure shielding or Hydro DMG Bonus in off-meta DPS builds.
- Circlet: HP% is most reliable; Crit stats if your team provides ample reaction damage.
3.2 Recommended Sets
- 4× Tenacity of the Millelith: Maximizes shield synergy and grants additional team buffs.
- 2× Tenacity + 2× Noblesse Oblige: Balances durability with burst damage.
- 2× Noblesse + 2× Heart of Depth: Enhances Hydro application for Vaporize setups.
4. Team Compositions & Synergy
4.1 Freeze Comp
Combine Dahlia with a Cryo DPS like Eula, a reaction enabler, and an EM buffer. Her shields keep the party safe while Freeze procs amplify damage.
4.2 Vaporize Rush
Pair her with Xiangling, Bennett, and an EM support for near-constant Vaporize under the protection of her barrier.
4.3 Overload Shield Bait
Use Dahlia’s barrier to bait Overload explosions, clustering foes for your Electro DPS units to capitalize on.
4.4 Geo Niche
In Geo-heavy challenges, her shield pairs well with stone constructs, granting breathing room for high-damage Geo carry characters.
5. Matchup Advice & Abyss Benchmarks
Test Dahlia’s HP-based shield against each Abyss floor’s key mechanics to map barrier thresholds. Adjust HP and Energy stats to cover burst and sustained hits.
6. Talent Priority & Banner Tips
Leveling: Prioritize Skill for consistent shielding, then Burst for extended Hydro coverage, and lastly normal attacks. Banners: She performs well at C0, with C2 as a sweet spot for shield strength and Energy Recharge. Higher constellations are niche but valuable for speedrunners or co-op boss rushes.
7. Conclusion
Dahlia reshapes the four-star support archetype with formidable HP-based shields, teamwide attack-speed buffs, and versatile Hydro zoning. Properly built and synergized, she can rival many five-star supports in both defense and damage assistance.
