Starlight Billy

Nekomata's signature but Billy's top option — Physical DMG% plus 25% bonus DMG when attacking from behind. Rewards staying at range and consistently hitting from behind targets.

Billy's own signature. 57.5% Physical DMG buff for 8s upon hitting an enemy from 6+ meters away with Basic or Dash Attacks — easily and permanently maintained, making it one of the strongest options for ranged Physical DPS.

Unconditional massive CRIT Rate and CRIT DMG with no management required — great stat stick for any Attack agent.

Near-permanent 20% CRIT Rate, always-active 45% CRIT DMG, and high Base ATK. Solid all-around option.

Good for Basic Attack-heavy rotations. Each stack has its own duration and only 1 can be gained every 0.5s — maintaining max stacks requires constant Basic Attacks.

Best F2P option. 25% unconditional ATK + 19.2% Combat ATK after Dodge Counter or Quick Assist. Easy to maintain with a support character on the team.

Decent burst option — effectively 72% Ultimate DMG against bosses where you can guarantee 3 Chains per stun. Falls behind in standard rotations without Ultimate ready.

Consistent but expensive to acquire. The on-CRIT proc deals Physical DMG that can't CRIT itself — non-Physical characters lose all elemental DMG% on that damage, limiting its value.
