Hey Proxies! If you’ve been cruising through New Eridu, you know that style is just as important as skill. And nobody—and I mean nobody—has more style than our favorite cyborg cowboy, Billy Kid. As a member of the Cunning Hares, Billy is your go-to Physical Attack character for clearing waves of Ethereals with flashy, long-range gunplay.

While Billy is a free character, don’t let that fool you. With the right gear, he can outshine even the rarest S-rank pulls. Let’s break down the best W-Engines, Drive Discs, and team comps to make your Billy Kid a legendary “Starlight Knight!”

Billy Kid: Build Overview

To turn Billy into a high-octane DPS machine, you need to focus on his Physical DMG and Crit stats. Here is the quick-reference table for his “God-tier” setup:

FeatureRecommended Selection
Primary AttributePhysical
Best W-EngineSteel Cushion (S-Rank) or Starlight Engine (F2P)
Core Drive Discs4-pc Woodpecker Electro + 2-pc Fanged Metal
Main Stats FocusAttack% / Physical DMG / Crit Rate
Best SynergyAnby Demara & Nicole Demara (Cunning Hares)

Building the Perfect Billy: Step-by-Step

Step 1: Choose the Right W-Engine If you have the resources, Steel Cushion is his best-in-slot weapon, providing a massive boost to Physical DMG and back-attack bonuses. For F2P players, the Starlight Engine is an incredible alternative. It increases your Attack whenever you land a Quick Dash or Dodge Counter—mechanics that are central to Billy’s kit.

Step 2: Optimize Your Drive Discs Drive Discs are where Billy’s damage really scales. We recommend a 4-piece Woodpecker Electro set. This set triggers an Attack buff whenever you land a critical hit with Basic Attacks or EX Special Actions. Pair this with a 2-piece Fanged Metal set for a flat 10% Physical DMG increase. This combo ensures Billy stays lethal throughout the entire fight.

Step 3: Master the Cunning Hares Synergy Billy shines brightest when paired with his teammates. Having Anby on the team helps Stun enemies faster, allowing Billy to deal massive damage during the “Daze” window. Nicole provides essential grouping with her black holes and reduces enemy Defense, making Billy’s ultimate hit like a freight train.
