Summon Night is a DLC weapon unlocked by the Shuto character. It generates damaging zones directly above the player in a vertical direction, and those zones linger for a duration after each activation — maintaining an active hitbox that deals damage to enemies passing through. The weapon is described as harder to use early on, requiring familiarity with its vertical-only coverage pattern before it becomes efficient.

• Generates a vertical (upward-direction) damage zone above the player on each activation
• The zone's hitbox lingers for a period after activation — enemies passing through continue to take damage
• Particularly effective against enemies approaching from directly above
• Early-game handling is less intuitive until the vertical-only pattern is internalized
• Duplicator (evolution material) grants Amount +1 — simultaneously increasing the zone count and serving as the evolution item

Hold Duplicator, level Summon Night to MAX, then open a treasure chest after 10:00 (evolved form name to be confirmed).

Duplicator grants Amount +1, directly increasing the number of zones deployed per activation while held as the evolution material — a dual benefit from a single item.

• Lingering vertical zones provide ongoing area denial above the player without requiring continuous activation
• Zones persist after placement — the player can reposition while damage continues in the original zone location
• Duplicator investment multiplies zone count, expanding vertical coverage significantly
• Effective against enemy patterns with strong vertical movement or top-down approach routes

• DLC-exclusive — requires purchasing the relevant DLC content and unlocking Shuto
• Vertical-only attack leaves horizontal and rear approaches completely unaddressed
• Early-game difficulty — the vertical placement pattern takes practice to use efficiently
• Effectiveness varies significantly depending on stage layout and enemy movement patterns

Shuto is the prerequisite character and the most natural fit. Stages with prominent vertical enemy approach routes maximize the weapon's coverage. Duplicator investment expands zone count and stabilizes the weapon's coverage, making it the most reliable configuration.

Summon Night's vertical zones require intentional positioning — place the player so enemy approach paths align with the upward coverage direction. Zones that intercept the route enemies travel from above deal multiple hits as enemies walk through the lingering hitbox.

Use the lingering zones for area denial: deploy a zone and reposition quickly to cover multiple vertical lanes simultaneously. With Duplicator expanding zone count, several vertical approach corridors can be blocked at once.

Supplement with a horizontal or omnidirectional weapon for flank and rear coverage. Summon Night handles the vertical approaches; the companion weapon covers horizontal and rear threats that fall outside the zone's reach.

Q. How do I unlock Shuto? A. Shuto is a DLC-exclusive character available after purchasing the relevant DLC and satisfying the character's specific unlock condition. Unlocking Shuto makes Summon Night available in runs.

Q. What direction is "vertical" exactly? A. The zone extends upward from the player's current position — the screen-up direction. Stages and enemy patterns with heavy north-south movement benefit most from this coverage orientation.

Q. Is Summon Night weak without Duplicator? A. It functions without Duplicator, but zone count is lower and vertical coverage is narrower. Duplicator significantly expands effective coverage — it is the highest-priority passive for maximizing the weapon's area denial capability.
