All W-Engine (Weapon) Guides

Elegant Vanity is the Best for Astra

Elegant Vanity provides a quality-of-life upgrade for Astra thanks to its energy gain and party-wide DMG buffs. You can also make do with other W-Engines that provide ATK or Energy Regen.

Best Astra Yao Drive Discs

Best Drive Discs and Set Bonuses

Drive Disc	Rating and Merits
Astral Voice (4-pc) Swing Jazz (2-pc)	★★★ - Best Set! Astral Voice is Astra's best Drive Disc since her kit revolves around the Quick Assist mechanic. A 2pc. Swing Jazz can help increase Astra's Energy Regen to easily access her EX Special Attack.
Astral Voice (4-pc) Hormone Punk (2-pc)	★★☆ - 2nd Best A 2pc. Hormone Punk also works well with Astra since more ATK means a stronger buff from her Core Skill.

Astra Skill Priority

Astra Talent Priority

Skill	Priority	Explanation
Core Skill	★★★★★	It's important to upgrade Astra's Core Skill first since it increases the DMG buff.
Basic Attack	★★★☆☆	Upgrade this after the high priority ones since it provides the most DMG when Astra is on-field.
Dodge	★★☆☆☆	You can save Astra's Dodge for last since it doesn't contribute much to her kit.
Assist	★★☆☆☆	Astra's Assist also doesn't do much in terms of damage.
Special Attack	★★★★★	Upgrading Astra's Special Attack is just as important as her Core Skill since this increases the DMG buffs during Idyllic Cadenza state.
Chain Attack	★★★★☆	Upgrading Astra's Chain Attack will increase the amount of healing she offers on her Ultimate, so upgrade this after her Core Skill and Special Attack.

Astra's Core Skill and Special Attack are a top priority for the DMG buffs they provide. Astra's Chain Attack should be next in line to increase the healing she provides from her Ultimate.
