Summon Night Vampire Survivors Guide

Patch v1.13 / Legacy of the Moonspell DLC

Spawns claws from the top of the screen. Area scales how far down they reach.

Base damage: 10Cooldown: 3.0sEvolves: Echo Night (Duplicator)

Summon Night drops claws from the top of the screen rather than firing from the character. The wiki effects block specifies the spawn axis directly: claws emerge above the player and leave a lingering dark-cloud damage zone behind them. Area scales how far DOWN those claws reach, which is the inverse of how Area works on most other weapons.

The second buried mechanic is the Ignores Speed tag. According to the wiki, Summon Night ignores Speed entirely, so Bracer's Projectile Speed component does nothing on this weapon. Duration scaling is fine, however, which extends how long the dark-cloud damage zones persist between claw drops.

Build context. Summon Night is Syuuto Moonspell's starting weapon in the Legacy of the Moonspell DLC, unlocked by surviving 15 minutes as Syuuto. The evolution into Echo Night gates on a max-level Duplicator, AND evolving the weapon unlocks Babi-Onna as a playable character through the LotM unlock chain.

This guide covers the top-down spawn mechanic, the Area-extends-downward scaling rule, the Echo Night evolution that gates on Duplicator, the Babi-Onna unlock that drops out of the same evolution chest, and the best Syuuto Moonspell build.

• What it is Summon Night, Syuuto Moonspell's Legacy of the Moonspell starter. Claws fall from above with lingering damage clouds.
• Evolves into Echo Night at max level with a max-level Duplicator. Unlocks Babi-Onna.
• Best with Duplicator, Empty Tome, and Spinach. Skip Bracer.
• Skip when the build leans on Projectile Speed (Bracer) for other weapons. Summon Night ignores Speed and wastes the slot on this side.

How Summon Night Works

Summon Night summons claws from the top of the screen above the character. The wiki effects block specifies the spawn axis as fixed: claws come from above, not from the player. After impact, each claw leaves a lingering dark-cloud damage zone that ticks damage for the Duration window. Area extends how far down the claws reach, which is functionally a vertical range slider.

Damage starts at 10 and climbs to 20 at level 8 (+10 over the track). Amount climbs from 1 to 4 (+3), which adds more claws per cycle. Duration scales from 1.0 second to 1.5 seconds (+0.5), extending the damage-zone persistence. Per the wiki, the weapon ignores Speed entirely, which makes Bracer's Projectile Speed component dead on Summon Night.

The Hitbox Delay of 0.45 seconds matters in actual play. When a claw spawns, there is a brief delay before the hitbox activates, then the lingering cloud takes over. According to the wiki, the Projectile Interval is 0 seconds, so all claws in a cycle spawn simultaneously rather than in sequence. The level-up Amount track is what makes the screen-coverage curve grow.

Stats and Mechanics

Per the wiki, Limit Break scales Summon Night with Might, Area, Duration, and Amount increments. The downward-reach property still applies under Limit Break, so stacked Area extends the vertical range further rather than the horizontal width. In actual play, this is the biggest screen-coverage scaler available to the weapon.

Echo Night Evolution and the Duplicator Gate

Summon Night evolves into Echo Night at max level with a max-level Duplicator in the inventory at minute 11 or later. The wiki specifies Duplicator as the single passive gate, which is the cleanest evolution pattern in the Legacy of the Moonspell DLC. The evolution chest also unlocks Babi-Onna as a playable character, which gives Duplicator a double purpose on Syuuto runs.

According to the wiki, Echo Night retains the top-down claw spawn pattern with faster fire rate, more claws per cycle, and longer damage-cloud Duration. The Babi-Onna unlock fires the moment the evolution proc completes, so the run does not need to continue past that point to lock in both rewards.

Best Syuuto Moonspell Build for Summon Night

Syuuto Moonspell's kit pairs the Summon Night starter with bonus Curse and a Might increase per level. The build below front-loads Duplicator for the evolution gate, then layers Spinach and Candelabrador for the damage and reach curves, finishing with defensive coverage since Syuuto has limited innate survival tooling.

Character Syuuto Moonspell (LotM lead; Curse and Might per level)

Passive 1 Duplicator (evolution gate + extra claws; first pick, every run)

Passive 2 Empty Tome (Cooldown reduces the 3.0-second cycle)

Passive 3 Spinach (Might scales the +10 damage track and the cloud ticks)

Passive 4 Crown (Growth speeds the climb to max Duplicator)

Passive 5 Mirage Robe (post-Babi-Onna unlock) (LotM companion weapon once the evolution lands)

Passive 6 Gale Force (LotM secondary; covers horizontal sweep that Summon Night misses)

Across multiple runs, this build is online around minute 11 once Duplicator reaches max and Echo Night fires. The Babi-Onna unlock drops at the same chest, so subsequent runs can swap to the Babi-Onna kit with the Mirage Robe starter. In actual play, the dark-cloud damage zones cover most of the screen height by minute 18 with stacked Area scaling.

Synergies and Arcanas

The wiki Combos table flags Duplicator, Empty Tome, Spinach, and Candelabrador as green-check picks. Candelabrador deserves special note here: Area on Summon Night extends the downward reach of the claws rather than the cloud size, so every +Area tick pushes the spawn coverage further down toward the bottom of the screen. The wiki specifies this directly in the effects block.

For arcana picks, Twilight Requiem (II) is a strong pair with the lingering cloud mechanic, since the arcana adds an echo to weapon casts. Per the wiki, the echo effect benefits weapons with Duration zones particularly well. Game Killer (0) is the safety pick when the run wants protection while the cloud zones establish coverage.

In real runs, Summon Night pairs cleanly with horizontal-sweep weapons that cover what the vertical claw drops miss. The wiki notes that LotM characters like Menya Moonspell and Babi-Onna run kits that pair vertical and horizontal coverage naturally. Once the Babi-Onna unlock fires from the Echo Night evolution, the natural follow-up build pivots to Mirage Robe on subsequent runs.

Summon Night Versus Song of Mana

Summon Night and Song of Mana are both vertical-axis AoE weapons but they fire from opposite directions. Per the wiki, Song of Mana fires a column above AND below the character, while Summon Night drops claws from the top of the screen downward only. Song of Mana ignores Amount and Speed; Summon Night only ignores Speed, so Duplicator is core to Summon Night and dead on Song of Mana.

Pick Summon Night when the build can support Duplicator for the Echo Night gate and the run wants the top-down spawn pattern. Pick Song of Mana when the build can run Skull O'Maniac and prefers the centered-column profile. In practice, the two cover overlapping screen zones, so most builds pick one rather than both unless the run has slots for two vertical-axis weapons.

Common Summon Night Mistakes

1. Skipping Duplicator early. Per the wiki, Duplicator is the single passive gate for Echo Night. The evolution chest also unlocks Babi-Onna. Defer Duplicator past the first three pick screens and the gate becomes uncertain by minute 11, which costs both the evolution AND the character unlock.
2. Stacking Bracer for Projectile Speed. Summon Night ignores Speed entirely. Bracer's Projectile Speed component goes to zero on this weapon, so a Bracer slot is wasted unless the run has a second Speed-scaling weapon online.
3. Misreading Area as horizontal scaling. Per the wiki, Area on Summon Night extends how far DOWN the claws reach, not how wide the cloud zones are. Players coming from other Area-scaled weapons sometimes overstack Area expecting wider coverage and get vertical reach instead.
4. Forgetting the Babi-Onna unlock chain. Per the wiki, evolving Summon Night into Echo Night unlocks Babi-Onna as a playable character. Stopping at the evolution chest without committing to the full Syuuto run wastes the second unlock.
5. Treating it as a stationary-spawn weapon. The claws drop from above the screen but they target where the character is at spawn time. Moving while the Hitbox Delay ticks (0.45 seconds) lets the player position the cloud zones for the next wave rather than where the spawn started.
