BEST S0 Augusta Guide & Build [Best Echoes, Weapons & Teams] - Wuthering Waves 2.6

Augusta is a 5‑star Electro Broadblade resonator. Her Ascension page shows that at Lv 90 she has 10300 HP, 463 ATK and 1112 DEF and that she wields a Broadblade. She uses the Electro element and gains additional stats when ascending/levelling her talents (e.g., Crit‑Rate +1.20% / 2.80% and ATK +1.80% / 4.20%). Her kit revolves around building Prowess and Majesty to unleash chain‑attack combos and Resonance Liberation forms.

Her Inherent Skills provide survivability and crit buffs:

1. Glory’s Favor – When Augusta deals damage, she gains a shield equal to 2.5 % + 350 of her max HP for five seconds; the shield can trigger every 0.5 s and does not stack.
2. Blazing Valor – When out of combat for 4 s, she restores a stack of Majesty and fully restores Crown of Wills, providing quicker access to her empowered states.

Her Resonance Liberation (Sunward Conquest) has two forms: Sword of Eternal Oath and Sublime is the Sun. The latter gives access to a Sworn Allegiance state where her heavy‑attack combos (e.g., Thunderous Backstep, Spin‑slash and Uppercut) gain Electro DMG and she can walk on water without using stamina. Ruler’s Realm (part of her Forte Circuit) lasts 30 s and grants the other resonator in the team a shield equal to 5 % + 650 of Augusta’s max HP when they use their Intro Skill; this cannot stack. The Forte also builds Majesty whenever allies cast their Outro Skills during Augusta’s Outro Skill. Her Outro Skill – Battlesong of the Unyielding increases the next resonator’s DMG amplification for all attributes by 15 % and grants one stack of Majesty and Crown of Wills to Augusta when she leaves the field.

Crown of Wills is a stacking buff that significantly enhances her offensive stats. The Resonance chain shows that:

1. With Stained in Scorched Earth, Crown of Wills caps at two stacks and each stack increases Crit DMG by 5 %.
2. Cleansed in Crimson War modifies Crown of Wills so that each stack increases Crit DMG by 20 %; additionally, every 1 % of crit‑rate above 100 % adds 2 % Crit DMG (up to 100 %).
3. Engraved in Radiant Light raises the cap to four stacks and each stack grants an extra 5 % Electro DMG bonus; performing her heavy attacks or uppercut during Sworn Allegiance grants a stack of Crown of Wills.

These mechanics make Augusta an on‑field heavy‑attack DPS that rewards aggressive play. High crit rate and crit damage increase the value of her Crown of Wills buffs, while staying on field allows her to maintain Majesty and perform long combo sequences.

Augusta’s kit scales from ATK, Crit Rate/Crit DMG and Electro / Heavy‑attack damage. The Resonance chain emphasises boosting crit and electro damage through Crown of Wills, while the Forte circuit and the weapon synergy emphasise heavy attacks. Therefore the best Echo sets for Augusta are:

1. 5‑piece Heavy‑Attack / Electro DMG set (Void Thunder) – look for echo sets whose 5‑piece effect increases Heavy‑Attack DMG or Electro DMG. Augusta’s heavy attacks (Spin‑slash, Thunderroar Uppercut and Backstep) deal Electro damage, so a set that increases heavy‑attack damage amplifies her primary damage source. If there is a set that boosts Electro DMG when using Resonance Liberation, it will also synergise with her Crown of Wills stacking buff.
2. Alternative 5‑piece ATK or DMG amplification set – if a heavy‑attack set is unavailable, use a set that provides a flat ATK% bonus and increases damage after casting Intro or Resonance Skills. Augusta spends much time in Sworn Allegiance, and such sets will provide consistent damage.

Based on the stat bonuses listed on her ascension page (Crit‑Rate +1.20%/2.80% and ATK +1.80%/4.20%), the recommended main stats for Echoes are:

1. Crit Rate → Crit DMG – build enough crit rate to reach or exceed 100% so that Cleansed in Crimson War converts excess crit rate into crit damage. Afterwards prioritise crit damage.
2. ATK% – her damage scaling is ATK‑based.
3. Electro DMG% or Heavy‑Attack DMG% – these further amplify the damage from her skills.
4. Energy Regeneration– additional energy helps re‑enter Sublime is the Sun quickly and maintain high uptime.

Because Crown of Wills and her resonance chain strongly reward crit rate and crit damage, Augusta should aim for the following approximate stat distribution:

1. ATK%: At least 90–100% from Echo main stats and substats; the high base ATK (463) and weapon ATK will scale well.
2. Crit Rate: Aim for ~100% so that excess crit rate is converted into crit damage via Cleansed in Crimson War.
3. Crit DMG: 150% or higher once crit rate is sufficient; Crown of Wills adds up to 20 % crit damage per stack and extra crit damage from high crit rate.
4. Electro DMG Bonus: 30% or higher from echo main stats and resonance chain; Engraved in Radiant Light grants 5% per stack of Crown of Wills (up to 20%).
5. Energy Regen: Enough to comfortably enter Resonance Liberation (Sublime is the Sun) whenever the buff window ends.

Augusta can function either as a main heavy‑attack DPS or as an off‑field buffer via her Outro Skill. Since the game emphasises synergy rather than strict roles, the following team archetypes work well:

Heavy‑Attack DPS team (Augusta on‑field)

1. Augusta (Main DPS) – stays on field, builds Prowess and Majesty, uses Sworn Allegiance to perform chains of Heavy Attacks and maintain Crown of Wills stacks. She benefits from other resonators’ Intro/Outro buffs and can provide a shield via Ruler’s Realm when they cast their Intro Skills.
2. Off‑field support/driver – choose a resonator whose Intro Skill deals off‑field damage or applies a debuff (e.g., elements that complement Electro) and whose Outro Skill buffs ATK or Electro DMG. Since Augusta’s Outro Skill gives the next resonator a 15 % DMG amplification buff, this resonator should have strong burst damage.
3. Defensive/healing support – a resonator that provides healing or additional shielding so Augusta can stay on field and continue heavy attacks. Although Glory’s Favor gives a self‑shield, her long combos may leave her open to interruption.

Buffer / burst‑support team (Augusta off‑field)

1. Primary DPS – a resonator with high burst damage who benefits from Augusta’s Battlesong of the Unyielding; when Augusta exits the field, the DPS receives 15 % DMG amplification for all attributes.
2. Augusta (Sub‑DPS/Buffer) – enters the field to build Crown of Wills and apply Ruler’s Realm; when she leaves, she grants DMG amplification and provides Crown of Wills stacks for her next rotation.
3. Utility support – a resonator providing healing/shields or energy regeneration. During Augusta’s downtime, this support can use their Outro Skill to build Majesty for Augusta.

Thunderflare Dominion:

1. Stats – At Lv 90 the Broadblade has 675 ATK and 12.2% crit rate, providing a high offensive baseline.
2. Syntonize effect (Thunderblaze Eminence) – Increases ATK by 12%. Casting Intro or Resonance Skills increases Heavy‑Attack DMG by 20 % for 15 s, and obtaining a shield allows Heavy‑attack DMG to ignore 7.2 % of the target’s DEF for 7 s (stacking up to five times). Augusta’s kit frequently uses Intro skills to enter her Stride of Goldenflare state and generates shields via Glory’s Favor, so she can maintain the heavy‑attack and DEF‑ignore buffs with little downtime.

Given these synergistic bonuses, Thunderflare Dominion is the most suitable Broadblade for Augusta. Its heavy‑attack damage bonus and DEF penetration complement her heavy‑attack‑centric playstyle, while the high ATK and crit‑rate stat scales with her Crown of Wills buffs. Other Broadblades should ideally provide crit‑rate, ATK% or Electro‑damage bonuses and have effects that trigger on Intro/Resonance Skills; however, the weapon page shows only Thunderflare Dominion, so it is recommended as her best option.
