Starlight - Billy Kid Best Build

Starlight - Billy Kid build overview

Starlight - Billy Kid is a S-Rank Physical Rupture Agent used as rupture. The build is designed around the Agent's active combat job, Additional Ability requirements and the short damage windows created by Daze, Anomaly buildup or team buffs.

Recommended main stats are DISC 6: HP, DISC 5: Physical DMG or HP, DISC 4: CRIT Rate or CRIT DMG. After equipping the correct main stats, prioritize CRIT Rate, CRIT DMG, HP%. A functional rotation and complete Drive Disc main stats provide more value than forcing perfect substats too early.

Best W-Engines

Starlight Rider Faceplate is the primary W-Engine recommendation because its stats and passive support Starlight - Billy Kid's Rupture mechanics. Other tested options include Starlight Rider Faceplate, Cauldron of Clarity, Radiowave Journey. Check that an alternative matches the Agent's Specialty and that its passive can remain active in the intended rotation.

Drive Discs and stats

The recommended setup is 4× Yunkui Tales with 2× Woodpecker Electro. The four-piece set supports the Agent's main damage, Anomaly, Daze or utility loop, while the two-piece set adds a reliable secondary stat. Strong individual pieces can temporarily outperform a forced complete set when the recommended main stats are missing.

Recommended teams

• Recommended squad: Starlight - Billy Kid (Rupture), Lucia Elowen (Support), Astra Yao (Support). This composition preserves the required damage, Daze, Anomaly or support jobs instead of relying on rarity alone.
• Alternative squad: Pulchra Fellini (Stun), Starlight - Billy Kid (Rupture), Anby Demara (Stun). This composition preserves the required damage, Daze, Anomaly or support jobs instead of relying on rarity alone.

Replace one Agent at a time while maintaining the same squad function. Attack and Rupture carries generally want controlled burst windows, Anomaly Agents need compatible buildup or Disorder partners, Stun Agents create openings, and Support or Defense Agents keep buffs and survivability available.

Skill priority

• Situational priority: Chain Attack.
• Situational priority: Dodge.
• Situational priority: Assist.
• Core priority: Core Skill.
• Damage priority: Basic Attack.
• Damage priority: Special Attack.

Raise the Core Skill and the abilities used during the main field time first. Lower-impact Dodge, Assist or Basic Attack levels can wait when the kit does not rely on them. Guaranteed Agent, W-Engine and important skill levels should be completed before extended Drive Disc farming.

Mindscape and investment

M0 is functional; M2 and M6 are the main investment checkpoints. The base Agent is intended to remain usable without premium Mindscape levels. Compare signature equipment and duplicate copies with new teammates that may improve the complete squad more than a personal damage upgrade.

Frequently asked questions

Does Starlight - Billy Kid need a signature W-Engine?

No. The signature is the premium choice, but a compatible alternative keeps the essential build functional.

What should be upgraded first?

Level the Agent and W-Engine, unlock important Core Skill nodes, equip correct main stats and then improve the abilities used in the main combat sequence.
