Anomaly Mastery

Though he is a handsome cyborg, he maintains a casual and carefree attitude. He is an ardent fan of the Starlight Knight show and often refers to himself as one of the Starlight Knights, reciting many classic lines from the series. He affectionately calls his pair of custom-made high-caliber revolvers “the girls,” which he received as a gift from an old friend. Despite his seemingly unreliable appearance, once Billy gets serious, he’s more than capable of taking on any challenge.

Billy Premium Team Explanation

Billy’s Role and Team Composition:

Role and Characteristics:

Billy functions as the secondary DPS within the team setup.
His damage output primarily stems from his long-ranged Basic Attacks and high mobility.
Billy’s survivability is enhanced by his ability to maintain a presence on the field through frequent attacks and mobility.

Synergy with Nicole and Zhu Yuan:

Nicole’s energy field reduces enemy DEF by 40% and boosts Ether DMG for the team by 25%.
This synergizes well with Zhu Yuan’s burst-oriented playstyle, known for short but intense bursts of damage.
Billy acts as a consistent damage source between Zhu Yuan’s burst cycles.

Bangboo Selection:

The optimal Bangboo choice for the team is the A Rank Devilboo.

Bangboo Choices:

Team Dynamics

Team Passives Activation:
- Billy and Nekomata: Same faction.
- Corin: Shares the same attribute with both Billy and Nekomata.

Roles and Equipment Adjustments

Billy:

Acts as the on-field character, focusing on Physical Anomaly.
Equipment attributes should emphasize Anomaly Proficiency and Anomaly Mastery to increase the buildup speed of Physical Anomalies.

Nekomata:

Role remains as support and burst damage dealer.
Equipment adjustment:
- New Setup: 4-piece Fanged Metal and 2-piece Woodpecker.
- This setup balances higher small bursts with enhanced Physical Anomaly capability.

Corin:

Role remains as the primary burst damage dealer during the Daze period.

Strategy

Billy’s Playstyle:
- Somewhat unconventional in this setup, requiring focus on Physical Anomaly.
- If a better Physical Anomaly character becomes available in the future, consider replacing Billy immediately due to his lower anomaly efficiency.

This composition ensures all team passives are fully activated and adjusts the equipment to optimize the roles and synergies within the Physical team.
