Phas3r generates thin horizontal damage zones across the field. Each activation sweeps multiple narrow beam-like strips horizontally, dealing damage to every enemy in their path. The core design is Amount scaling: each additional Amount point multiplies the number of damage zones generated per activation.

• Multiple thin horizontal damage strips sweep across the field on each activation
• Amount increases multiply the zone count directly — high Duplicator value
• Strong horizontal coverage but gaps between zones allow enemies approaching from directly above or below to pass through unharmed
• Empty Tome (cooldown reduction) synergizes naturally as both an evolution material and a stat boost

Hold Empty Tome, level Phas3r to MAX, then open a treasure chest after 10:00 (evolved form name to be confirmed).

Empty Tome's cooldown reduction applies while held, increasing Phas3r's activation frequency before and during the evolution process.

• Outstanding Amount scaling — Duplicator investment multiplies total damage rapidly
• Wide horizontal zone coverage clears enemy rows efficiently
• Empty Tome simultaneously provides evolution material and cooldown reduction synergy
• No manual aiming required; positioning relative to enemy formations is the key skill

• Vertical coverage is weak — enemies approaching from directly above or below slip through zone gaps
• Raw damage per zone is modest; not a high-burst weapon in isolation
• Thin zones miss single isolated enemies frequently
• Unlocking requires reaching level 7 in a run, so the weapon must be found and leveled early

Characters who start with Phas3r or who level up quickly are ideal. Stages where enemies approach in long horizontal formations maximize the zone coverage advantage.

Duplicator is the highest-priority investment: each additional Amount point adds more zones per activation, compounding faster than raw Might increases at high amounts. Multiple Duplicators dramatically change Phas3r's damage ceiling.

To address the vertical weakness, either Candelabrador (wider zones) or a secondary weapon with vertical/orbital coverage (e.g., a rotating weapon) can fill the gap effectively.

Stacking both Empty Tome and Crown achieves a substantial cooldown reduction, making zones appear at very high frequency. High frequency combined with high zone count creates a state where the field is almost continuously covered by damage strips.

Q. Can any character unlock Phas3r at level 7? A. Yes — any character who finds Phas3r during a run and levels it to 7 will unlock it. No specific character is required.

Q. How do I compensate for the vertical weakness? A. Candelabrador (Area) widens the zones to cover more vertical space. Alternatively, a secondary weapon with orbital or radial coverage handles enemies that slip through the horizontal gaps.

Q. Does Empty Tome conflict with King Bible? A. Empty Tome is also the evolution material for King Bible → Unholy Vespers. If running both Phas3r and King Bible, decide early which evolution to prioritize, since only one weapon can use the Empty Tome for evolution per run.
