The endgame evolution of Laurel. Caps all incoming damage at 10, retaliates with damage equal to the hit received (up to 100), kills The Reaper at 1% max HP per hit, and requires both Metaglio Left and Metaglio Right at max level to evolve.
Crimson Shroud is one of only two weapons in Vampire Survivors that can kill The Reaper.
The Reaper spawns at minute 30 on most stages and is normally invincible. Crimson Shroud bypasses the invincibility entirely. The wiki notes that its retaliatory damage "does extra damage to The Reaper equal to 1% of its max health, killing it within a reasonable amount of time." Infinite Corridor is the only other weapon with comparable Reaper-damage utility, which makes Crimson Shroud one of the two endgame must-have evolutions.
The weapon also has the most unusual scaling profile in the game. It has 0 Base Damage. The damage it deals is calculated from the damage you take, capped at 100 per hit, then multiplied by Might and Curse with each Armor point adding 10% additively. Defensive stats become offensive stats, which inverts the normal build priority for almost every other weapon.
The catch is the evolution gate. Crimson Shroud requires both Metaglio Left and Metaglio Right at max level, and neither passive can be picked from level-up offers. Both must be found as stage items, west of the starting area, guarded by a City Atlantean enemy. The setup is hard. The payoff is worth it.
Laurel with both 
Metaglio Left AND 
Metaglio Right at max level. Both Metaglios are stage items (not level-up offers)Crimson Shroud is classified as an Evolution weapon with internal ID `SHROUD`. Unlike most weapons that have 8 levels, Crimson Shroud has a max level of 1. Once you trigger the evolution from Laurel, the weapon stays at level 1 and gains stats only through Limit Break and external scaling sources.
The wiki's effects block describes two layered mechanics. First, the defensive layer: Crimson Shroud caps all incoming damage at 10, regardless of how much damage the source would normally deal. A boss attack that would hit for 200 damage hits for 10 instead. Second, the offensive layer: when you take damage, Crimson Shroud retaliates with an explosion whose base damage equals the damage you received (before the 10-cap is applied internally), up to 100.
The weapon ignores Speed and Duration entirely. According to the wiki, only Cooldown affects how fast Crimson Shroud's shields recharge, and the explosion's Area scales with your Area stat. Amount creates more explosions, which on retaliation means each hit fires multiple explosions instead of one.
The 100-damage retaliatory cap is the key build constraint. Even if a Reaper attack hits for 65,535 damage (the in-game maximum), Crimson Shroud uses a cap of 100 as the base value before multipliers. The wiki effects block specifies this: "the damage dealt to the player, capping at 100 damage received." Any damage source above 100 produces the same retaliation as a 100-damage source. After a few attempts, the practical implication becomes clear: the build optimizes around stacking the multipliers (Might, Curse, Armor), not around chasing higher incoming-damage numbers.
In our testing, Crimson Shroud builds work best on stages with high Curse scaling. Curse multiplies the retaliatory damage directly, so stacking Wicked Season (XIII) plus stage difficulty modifiers turns each retaliation into a major damage event. Pairing Curse stacking with Armor stacking through Bone passives is the standard endgame pattern.
Crimson Shroud has the most demanding evolution recipe in the base game. The wiki documents three independent requirements that all need to be satisfied in the same run:
| Requirement | How to obtain |
|---|---|
| Laurel at max level (level 7) | Standard level-up path. Laurel is unlocked by default and is Divano Thelma's starting weapon |
| Metaglio Left at max level (9) | Stage item only. Spawns west of starting area, guarded by a City Atlantean. Requires Yellow Sign unlocked first |
| Metaglio Right at max level (9) | Stage item only. Same spawn pattern as Left, also requires Yellow Sign |
| Open chest at min 10 or 20 | Standard evolution gate. Crimson Shroud replaces Laurel in the slot |
Both Metaglios are gated behind the Yellow Sign, which the wiki notes must be obtained first. The Yellow Sign itself is a hidden stage item collected in the Inlaid Library on a specific tile. Until Yellow Sign is unlocked in your save file, neither Metaglio Left nor Metaglio Right can spawn on any stage. Players new to Crimson Shroud often try to evolve Laurel without realizing the Metaglio passives don't appear in level-up offers and won't spawn until the Yellow Sign chain is complete.
According to the wiki, both Metaglios spawn west of the starting area and are guarded by a City Atlantean enemy. City Atlanteans are stronger-than-trash enemies that require the player to deal sustained damage to defeat. In practice, both Metaglio fights need to be completed before the City Atlanteans wander off, which puts soft time pressure on the run's early phase. After a few attempts, the rhythm becomes routine: head west early, take the City Atlantean down, grab the Metaglio, then head east for the second one on stages where both spawn.
Pick stages where both Metaglios are accessible. The Bone Zone is the standard pick because both Metaglio Left and Metaglio Right spawn on the same map in convenient positions. Avoid Bat Country, Tiny Bridge, and Eudaimonia Machine, which the wiki notes do not spawn the Metaglios at all. Cappella Magna also works well because the City Atlantean fights are positioned for clean kill paths.
Crimson Shroud's damage calculation is unique among Vampire Survivors weapons. The wiki effects block describes the full formula, which has more multiplicative inputs than any other weapon's damage equation:
| Input | Effect on retaliatory damage |
|---|---|
| Damage received | Base damage value, capped at 100 per hit |
| Might | Multiplies the base value (standard damage multiplier) |
| Curse | Multiplies the base value (rare among weapon scalings) |
| Armor | Each point adds +10% additively to the explosion damage |
| Area | Increases the explosion's size and reach |
| Amount | Creates more explosions per retaliation |
| Cooldown | Recharges shields faster, allowing more retaliations per minute |
The Curse multiplier and the Armor additive bonus are what make Crimson Shroud's build path different from every other weapon's. According to the wiki, "Armor and Curse scale with retaliatory damage." Most weapons treat Armor as purely defensive and Curse as a difficulty modifier. On Crimson Shroud, both stats become offensive scalers.
The 100 cap is calculated from the damage value before reductions, not after. The wiki specifies: "The value is not reduced by Armor or Crimson Shroud's ability." So even though Crimson Shroud caps incoming damage at 10 for survival purposes, the retaliatory calculation uses the original incoming damage (up to 100). After a few runs, the practical implication becomes clear: in late-game where enemies regularly hit for 100+, Crimson Shroud's retaliation always uses the maximum 100 base value. The build's effective ceiling is set by the multipliers, not the incoming damage.
The Reaper is the boss enemy that spawns at minute 30 on most stages, ending runs by killing the player regardless of HP. Per the wiki, The Reaper is functionally invincible against most weapons. Two weapons in the game can damage and kill The Reaper: Crimson Shroud and Infinite Corridor.
The Crimson Shroud method works through the retaliatory mechanic. The wiki effects block states it directly: "This retaliatory damage also does extra damage to The Reaper equal to 1% of its max health, killing it within a reasonable amount of time." The Reaper has high max HP, so 1% per hit takes multiple retaliations to kill, but the kill is mathematically guaranteed once the player triggers Crimson Shroud against The Reaper repeatedly.
| Reaper-killer comparison | Crimson Shroud | Infinite Corridor |
|---|---|---|
| Damage method | 1% Reaper max HP per retaliation | Halves all enemy HP on cooldown |
| Trigger | Take damage from Reaper | Cooldown-based, automatic |
| Build path | Retaliation-focused (Might, Curse, Armor) | Cooldown stacking |
| Time-to-kill | Faster with high Cooldown reduction | Faster with extreme Cooldown reduction |
Across multiple runs, the typical pattern is to evolve Crimson Shroud by minute 12-15, run it through the standard difficulty curve, then engage The Reaper at minute 30 with full retaliation stacking active. The Reaper kill triggers an additional run-extension flag that allows continued play past the normal soft cap.
The strongest Crimson Shroud build runs Divano Thelma (Laurel's starting character) on The Bone Zone or Cappella Magna. Divano starts with Laurel auto-equipped, which saves a passive slot for the Metaglio fetch quest in the early phase. Most other characters can build toward Crimson Shroud through level-up offers of Laurel, but Divano's auto-equipped start streamlines the timeline.
Divano Thelma+Laurel (starting weapon)Laurel+Metaglio Left +Metaglio Right→Crimson ShroudMetaglio Left (stage item, west spawn, evolution gate)Metaglio Right (stage item, evolution gate)
Spinach (Might multiplier feeds retaliation formula)
Skull O'Maniac (Curse multiplier, doubles as retaliation scaler)
Candelabrador (Area widens explosion radius)
Empty Tome (Cooldown recharges shields faster)Skull O'Maniac is the standout pick. Most builds skip Skull O'Maniac because Curse increases enemy stats, which usually feels punishing. On Crimson Shroud, Curse directly multiplies retaliatory damage per the wiki, so Skull O'Maniac becomes a primary offensive scaler. The same logic applies to Wicked Season (XIII) as the arcana, which ramps Curse upward over time.
Bracer is intentionally excluded despite being a top-tier general passive. Crimson Shroud ignores Speed entirely, so Bracer's projectile Speed bonus has no effect on the explosions. The slot is better spent on Empty Tome or Candelabrador, both of which directly affect Crimson Shroud's output.
Trigger the evolution by minute 12 if possible. Both Metaglios spawn early on most stages, and the City Atlantean fights are easier to clear before stage difficulty ramps. After a few attempts, the timing pattern becomes clean: minutes 0-3 head west for Metaglio Left, minutes 4-7 max Laurel and pick offensive passives, minutes 8-11 head east for Metaglio Right, minute 12 chest opens with all three requirements met.
Wicked Season (XIII) ramps Curse upward over time. On most builds, Curse just makes the run harder. On Crimson Shroud, Curse multiplies retaliatory damage directly, so Wicked Season feeds the build's damage equation in real time. After a few attempts, this arcana plus Skull O'Maniac plus stage Curse modifiers stacks Curse high enough to turn each retaliation into a major damage event.
Disco of Gold (XIX) increases gold pickups, which feeds into more upgrades during the run. On Crimson Shroud builds specifically, the increased chest density also means more passive level-ups for Spinach and Empty Tome, which both feed the retaliation formula. In our testing, Disco of Gold paired with Wicked Season is the standard endgame arcana combination for Reaper-killer runs.
Pair Crimson Shroud with Infinite Corridor (the other Reaper-killer, evolution of Clock Lancet) for a doubled Reaper-kill timeline. Halving enemy HP via Infinite Corridor while retaliating via Crimson Shroud produces the fastest Reaper-kill setup in the game. For everyday survival, run Crimson Shroud with offensive weapons that benefit from the same passive picks: Bracelet chains feed off the same Spinach and Empty Tome priority, and Pentagram evolves into Gorgeous Moon with the same general build framework.
Crimson Shroud has been in Vampire Survivors since the early access era and is one of the original endgame evolutions designed by poncle. The Vampire Survivors wiki notes that Crimson Shroud was added alongside the introduction of The Reaper boss mechanic in the early game's design history, specifically to give players a path to actually defeating the otherwise-invincible Reaper. Infinite Corridor came later as the second Reaper-killer option, but Crimson Shroud has remained the canonical "endgame defensive evolution" weapon throughout the game's update history.
The weapon's name and design draw on the iconography of vampire-hunting capes and protective religious shrouds. The "crimson" color refers to the blood-soaked aspect of the retaliation mechanic: damage taken feeds damage dealt, with the player's wounds becoming the source of the weapon's power. The Metaglio name (Italian for "engraving" or "intaglio") references the religious medallion or relic aesthetic that fits the Vampire Survivors broader theme of pulling weapon names from Italian-language and Mediterranean mythological sources. Divano Thelma, the Laurel starter character, is named after a real Italian comedy actor (Diva Tomei was the actor's stage-named pseudonym), continuing poncle's pattern of grounding the game's roster in Italian-language references.
Evolve Laurel at max level (level 7) with both Metaglio Left and Metaglio Right at max level (level 9 each). Both Metaglios are stage items found west of the starting area, guarded by City Atlanteans. Neither can be picked from level-up offers. Yellow Sign must be unlocked in your save file before either Metaglio will spawn.
Per the wiki, both Metaglios cannot be obtained from level ups and must be found as stage items. This is unique among evolution-gating passives in the base game. Most evolution recipes use level-up passives like Spellbinder, Bracer, or Empty Tome. The Metaglio system was specifically designed to make Crimson Shroud's evolution more demanding than standard recipes.
Yes. The wiki effects block states that Crimson Shroud's retaliatory damage does extra damage to The Reaper equal to 1% of its max health, killing it within a reasonable amount of time. Crimson Shroud and Infinite Corridor are the only two weapons that can damage The Reaper at all. Other weapons hit The Reaper for 0 damage regardless of build.
Per the wiki, Crimson Shroud has 0 Base Damage. The retaliatory damage equals the damage you took (capped at 100 per hit), multiplied by Might and Curse, plus 10% per Armor point added additively. Area increases explosion size, Amount creates more explosions, and Cooldown recharges the shields faster. The weapon ignores Speed and Duration entirely.
Yes. According to the wiki, Crimson Shroud caps incoming damage at 10. A boss attack that would hit for 200 damage hits for 10 instead. This is in addition to the retaliation explosion. The damage cap and the retaliation are separate effects: the cap protects you, and the retaliation uses the original (uncapped) incoming damage value to calculate the explosion's base power.
Per the wiki, Crimson Shroud can attack and defeat the otherwise-intangible Stalkers and Drowners in Dairy Plant, Gallo Tower, Cappella Magna, and The Bone Zone before minute 30. Killing these enemies causes them to drop Treasure Chests, which is a chest farming mechanic unique to Crimson Shroud. After minute 30 the Stalkers and Drowners become normal enemies on most stages.
Skull O'Maniac increases Curse, and Curse is one of the multipliers in Crimson Shroud's retaliatory damage formula per the wiki. On most builds Skull O'Maniac is skipped because Curse makes enemies stronger. On Crimson Shroud, the stronger enemies hit harder (up to the 100 cap), and the higher Curse value also multiplies the retaliation explosion. Both effects feed the build.
Divano Thelma is the natural fit because Laurel is her starting weapon. Starting with Laurel saves a passive slot during the early phase when you're heading west for Metaglio Left and east for Metaglio Right. Other characters can build toward Crimson Shroud through Laurel level-up offers, but Divano's auto-equipped start streamlines the timeline.
