Dehya's unique kit allows for remarkable build flexibility, enabling her to fill various roles within a team. While initial community perception often highlighted her struggles as a direct damage dealer, optimizing her artifacts and weapons can transform her into a valuable asset, whether she's on-field, off-field, or supporting her allies. As of 2025, careful consideration of her scaling and team needs is paramount. For players who want Dehya to be the main damage dealer, focusing on her Elemental Burst and a balance of ATK and HP is key. * Weapons: * Beacon of the Reed Sea (5-star): Dehya's signature weapon is often her best-in-slot for a DPS role. It provides CRIT Rate substat and increases ATK when Elemental Skill is used or when the character takes damage, and grants HP% if not shielded. This perfectly aligns with her kit. * Wolf's Gravestone (5-star): A strong universal option, providing a high ATK% substat and an ATK buff for the entire party. * Redhorn Stonethresher (5-star): Offers a substantial CRIT DMG bonus, which can be very impactful if other ATK sources are available. * Serpent Spine (4-star): A Battle Pass weapon that provides CRIT Rate and a damage bonus. However, Dehya's damage mitigation can make maintaining stacks difficult due to her HP fluctuating. * Verdict (5-star): Another good CRIT Rate option. * Tidal Shadow (4-star) / Talking Stick (4-star): F2P options that can perform well under specific conditions (healing, consistent Pyro application). * Akuoumaru (4-star): Offers ATK% and Elemental Burst DMG increase. * Artifact Sets: * 4-piece Emblem of Severed Fate: This is often the best choice for a burst-focused Dehya, as it significantly increases Elemental Burst DMG based on Energy Recharge. Given her high Burst cost, building ER is often necessary, making this set highly efficient. * 4-piece Crimson Witch of Flames: Ideal for maximizing Pyro DMG and elemental reaction damage (Overloaded, Burning, Vaporize, Melt). It boosts Pyro DMG and further enhances reaction damage after using an Elemental Skill. * 4-piece Vourukasha's Glow: A strong option that increases Elemental Skill and Burst damage based on HP lost, which synergizes well with Dehya's Redmane's Blood mechanic, especially at C1+. * 4-piece Marechaussee Hunter: Excellent if paired with Furina, as it grants CRIT Rate based on HP fluctuation. * 2-piece mixes: (e.g., Crimson Witch + Noblesse Oblige, Emblem of Severed Fate + Tenacity of the Millelith, or two 18% ATK sets) can be viable if full sets are difficult to obtain with good substats. * Stat Priority: * Sands of Eon: ATK% or Energy Recharge% (if struggling with Burst uptime). * Goblet of Eonothem: Pyro DMG Bonus. * Circlet of Logos: CRIT Rate or CRIT DMG. * Substats: Prioritize CRIT Rate/CRIT DMG, then Energy Recharge (to 180-200% usually), ATK%, and HP%. * Talent Priority: Elemental Burst > Elemental Skill > Normal Attack. This build focuses on maximizing Dehya's defensive utility, making her an excellent choice for teams that need interruption resistance and damage mitigation. * Weapons: * Favonius Greatsword (4-star): A prime choice for energy generation, helping the entire team with their Burst uptime. Requires building some CRIT Rate on Dehya to consistently proc its passive. * The Bell (4-star): Provides HP% substat and a shield, further enhancing her survivability. * Sacrificial Greatsword (4-star): Offers a chance to reset her Elemental Skill cooldown, increasing Fiery Sanctum uptime. * Katsuragikiri Nagamasa (4-star): Provides Energy Recharge and increases Elemental Skill damage. * Artifact Sets: * 4-piece Tenacity of the Millelith: This is often the best choice for support Dehya. It increases HP by 20% (2-piece) and, when an Elemental Skill hits an opponent, increases all party members' ATK by 20% and Shield Strength by 30% for 3 seconds. This can be triggered off-field, providing a consistent team buff. * 2-piece HP% sets: Combinations of Tenacity of the Millelith, Vourukasha's Glow, or other HP% sets for increased survivability. * Stat Priority: * Sands of Eon: HP%. * Goblet of Eonothem: HP%. * Circlet of Logos: HP% or CRIT Rate (for Favonius Greatsword). * Substats: Prioritize HP%, then Energy Recharge, and CRIT Rate. Aim for around 50,000 HP for optimal tanking. * Talent Priority: Elemental Skill > Elemental Burst > Normal Attack. Her skill is paramount for her support capabilities. Dehya's off-field Pyro application from her Elemental Skill can make her a viable trigger for transformative reactions like Burgeon and Overload. * Weapons: * Mailed Flower (4-star): A strong Elemental Mastery weapon that increases ATK and EM when triggering reactions. * Makhaira Aquamarine (4-star): Provides Elemental Mastery and an ATK buff to the team based on the wielder's EM. * Bloodtainted Greatsword (3-star): An accessible EM option. * Rainslasher (4-star): Another EM weapon, particularly good in Vaporize teams. * Artifact Sets: * 4-piece Flower of Paradise Lost: This set directly boosts the damage of Burgeon, Hyperbloom, and Aggravate reactions based on Elemental Mastery. * 4-piece Gilded Dreams: Increases Elemental Mastery and ATK, beneficial for reaction damage. * 2-piece Elemental Mastery sets: Combine sets like Wanderer's Troupe, Gilded Dreams, or Flower of Paradise Lost for raw EM. * Stat Priority: * Sands of Eon: Elemental Mastery. * Goblet of Eonothem: Elemental Mastery or Pyro DMG Bonus. * Circlet of Logos: Elemental Mastery. * Substats: Prioritize Elemental Mastery, then Energy Recharge, HP%, and ATK%. Aim for around 900 Elemental Mastery. * Talent Priority: Elemental Skill. Her Burst is less critical for this role unless specific team needs arise.
