Billy Best Builds, Guide, & Review

Billy is a free Agent you receive upon starting the game, and is an Attack Agent. This means that Billy is built as a damage oriented Agent, with teammates to help increase his damage.

As a free character, Billy is meant to be a fairly simple and straightforward character to play. While this is somewhat true, there are techs and moves you can do to maximize Billy's damage.

This mainly has to do with his crouching state, keeping uptime on buffs, etc.

Overall, Billy is able to perform well in endgame content with enough investment, but his output is on the lower end of the DPS Agent spectrum.

1. Core Passive
2. Basic Attack
3. EX Special / Ultimate
4. Dodge / Assist

Limited S-Rank Engines such as Heartstring Nocturne, Zanshin Herb Case, or Severed Innocence are great stat sticks. While the passive may not apply, the amount of Crit stats these Engines give is enough to beat out other options. However, you need to ensure you balance your offensive stats (ATK/Crit Rate/Crit DMG). If you overinvest into 1 or 2 categories, you won't be optimizing your damage.

Starlight Engine Replica is an A-Rank gacha Engine that works great with Billy, and can even be best in slot at max copies [5]. You do need to be aware of keeping up the buff, but it shouldn't be too difficult to maintain with Billy. At lower copies, a F2P option may perform better.

The Brimstone is a Standard S-Rank Engine available in the Signal Shop. It's a solid all around Engine for any Attack Agent. However, we don't recommend purchasing from the Signal Shop, as other F2P options are quite competitive. Marcato Desire was an event exclusive Engine, and Starlight Engine is craftable. Both of these are great options.

Woodpecker Electro is the go to Drive Disc set for Billy. You can use Puffer Electro as more of a Burst DPS style, but it's definitely more niche.

2-Pc is very flexible, simply pick anything with an offensive stat bonus like ATK%, Physical DMG, Pen Ratio, Crit DMG, etc.

Main stats and substats are also pretty straight forward, balance your Crit Rate / Crit DMG / and ATK values.

M1 Dazzling Entrance grants some Energy generation, but it's nothing major. M3 and M5 are also +2 skill level, which will increase Billy's damage, but once again, not a major buff.

M2 Roaming Gunslinger allows Billy to Perfect Dodge while doing Rolling Shot. This will automatically follow up into a Dodge Counter. You can trigger this move and a Defensive Assist at the same time for some extra damage.

M4 Starlight Ballistics grants increased Crit Rate on EX Special the closer Billy is. This is opposite of Replica Starlight Engine, but you simply need to maintain the Engine buff and use EX Special while close to the enemy. Because of M4, you don't want to overinvest into Crit Rate.

M6 Starlight Hero is a solid damage increase that is maintained as long as you are not hit by the enemy.
