Billy Builds are included in this guide, you can jump to Billy Build Here.
As the only pure ranged character among the beginning characters. Billy can ensure the minimum movement requirement for players. Easy to operate and flexible in action, maintaining a safe distance and pulling with strong enemies forms the core gameplay of Billy.
Crouching Shot
Billy is a physical attribute on-field main DPS. His move set is very special; the second half of the crouching shot can be infinitely extended by holding down Basic Attack. Once you enter the crouching shot and hold it, you can shoot endlessly as long as you don’t plan to stop. Billy’s damage increase mechanism also boosts the damage of this crouching shot. The output logic is simple, but the multiplier of Billy is relatively low when it is compared with other characters. The on-field performance in terms of DPS is even lower than the Corin, not to mention other S-rank characters. This makes Billy a character with a low Maximum DPS ceiling. However, his easy output method, and safe attack distance still make him a reliable character for difficult stages.

For Billy’s best performing W-Engine, the A Rank Starlight Engine Replica is his best choice. Since Billy is a high-mobility agent that most of his damage contributed by Basic Attack, Dash and Dodge, Starlight Engine Replica can provide such advantage, as also he is a ranged, the effect requirement from Starlight Engine Replica can be easily triggered by him.
S Rank Steel Cusion made Billy’s second top choice . This engine increases Physical DMG by 20%, and attacks from behind get an extra 25% boost. Billy is a high-mobility agent who can position himself easily with Dash and Dodge so he can attack enemy from behind most of the time active on the field. Easily achieving this W-Egnine’s 45% increase in attack. Additionally, Steel Cushion boosts Crit Rate.
Alternative W-engines for Billy is Cannon Rotor. This W-Engine provides a high Crit Rate passive and can deal 275% ATK as additional damage when Crit is triggered every 8s. If Billy is equipped with the Cannon Rotor, other of his gear should focus on stacking Crit Rate to ensure he can consistently trigger the W-engine’s effect whenever he is on the field.
For the early game stage, you can use [Lunar] Pleniluna as transitional options. These B Rank weapons provide ATK boosts. [Lunar] Pleniluna increases the damage of Basic Attack, Dash Attack, and Dodge Counter.

Main Stats

Sub Stats
For Disk Drives, it is recommended to equip Billy with 4 pcs Fanged Metal or 4 pcs Hormone Punk with 2 pcs Woodpecker Electro or 2 pcs Hormone Punk.
For Fanged Metal 2 pcs provides a 10% Physical DMG boost, 4pcs allows the team to place a debuff on enemy with an additional 35% damage.
For Hormone Punk you can decide to go for 2 pcs or 4 pcs. Its 2 pcs provides 10% damage buff, while 4 pcs increase 20% damage for 10s when entering combat or switching in, with 20 CD.
The 2 pcs bonus of Woodpecker Electro increases Crit Rate.
For main stats, Slot 4 should be Crit Rate or Crit DMG, Slot 5 is best with Physical DMG Bonus, followed by PEN (Penetration). Slot 6 should have Energy Regen or ATK%, both aiming to increase the single-use damage of Ex Special or the frequency of Ex Special usage. For sub-stats, prioritize Crit Rate and Crit DMG, followed by ATK% and PEN.
Attack
Support
Burst
Billy is the Sub DPS for this team, and as his damage output are mainly sourced from Basic Attacks and Dodges, Billy can be able to survive on field for long time with his long-ranged high frequent attacks and high mobility. Nicole’s energy field grants the enemies ijn the field a 40% reduction in DEF and a 25% boost in Ether DMG to the team, this can align perfectly with Zhu Yuan’s playstyle, known for short-duration but high-intensity bursts. Between them, use Billy as damage filler. For Bangboo, the A Rank Devilboo is the best choice for the team.
Anomaly
Support
Burst
If Zhu Yuan is unavailable, consider replacing her with Nekomata and Corin to form a Pure Physical team. Use Butler and Starterboo as the team’s best choice. Billy and Nekomata belong to the same faction, and Corin shares the same attribute with the other characters, ensuring all team passives are fully activated. Billy’s playstyle here is somewhat unconventional, as he needs to be the on-field character focusing on Physical anomaly. Therefore, equipment attributes should emphasize Anomaly Proficiency and Anomaly Mastery to increase the buildup speed of Physical Anomaly.
Nekomata and Corin’s roles remain largely unchanged as support and burst damage dealers. However, Nekomata’s equipment needs adjustment. Since Billy’s output rhythm shifts from focusing on Daze to balancing Daze and attribute anomalies, Nekomata’s equipment should be changed to 4 pcs Fanged Metal and 2 pcs Woodpecker to achieve both higher small bursts and Physical anomaly capability. Note that Billy’s anomaly efficiency is not particularly high, so if a better Physical Anomaly character appears in future, consider replacing him immediately.
