How to Defeat Red Death Reaper and Unlock Mask of the Red Death

Defeating
The Reaper at the 30:00 mark in Vampire Survivors requires evolving Clock Lancet into Infinite Corridor and Laurel into Crimson Shroud to withstand 65,535 touch damage while rapidly halving boss health.
The Reaper Spawn Mechanics and Scaled Health Formula
When the standard stage timer reaches 30:00, The Reaper appears to end the survival run. The health pool of The Reaper is precisely 65,535 multiplied by the character level reached upon spawn. Reaching the final minute at level 100 creates an entity with 6,553,500 health, while an early level 2 encounter produces 131,070 health. Additionally, The Reaper inflicts 65,535 damage per hit alongside a swift 1,200 movement speed, instantly eliminating any player lacking defensive barriers. Subsequent reapers spawn every additional minute, making quick target neutralization essential. Prepare for late mob swarms by reading our Cappella Magna stage guide.

Core Evolutions: Infinite Corridor and Crimson Shroud
Slaying The Reaper without relying on unintended map geometry requires two specific weapon evolutions, covered in our all weapon evolutions guide:
First, Infinite Corridor evolves from a fully leveled level 7 Clock Lancet combined with maxed level 9
Silver Ring and
Gold Ring. While Clock Lancet shoots freezing beams in clockwise directions, Infinite Corridor creates a 12-point clock aura culminating in a rotating frost wave. Each pulse strips exactly 50% of current health from every enemy on screen. Against The Reaper, repeated activation rapidly cuts millions of health down into manageable amounts.
Second, Crimson Shroud evolves from level 7 Laurel paired with maxed level 9
Metaglio Left and
Metaglio Right. While Laurel generates temporary shield barriers, Crimson Shroud limits all incoming damage to a maximum threshold of 10, which armor further reduces down to 1. Furthermore, whenever an attack hits the shield charge, Crimson Shroud retaliates with an explosive shockwave dealing direct percentage counter damage to The Reaper.

| Base Weapon | Evolved Weapon | Required Passives | Primary Combat Function |
|---|---|---|---|
| Silver Ring, Gold Ring | Halves all enemy current health by 50% with rotating frost bursts | ||
| Metaglio Left, Metaglio Right | Caps incoming damage to 10 and retaliates with explosive counter hits |
White Hand Encounter and Unlocking Mask of the Red Death
Once The Reaper is vanquished through the combined power of Infinite Corridor and Crimson Shroud, the boss dissolves and drops five Golden Eggs. Slaying The Reaper in any fashion completes the unlock requirement for
Mask of the Red Death. Immediately following the defeat, a gray entity named White Hand descends from above the screen. White Hand deals inexorable damage, bypassing all shield invulnerability and revival charges to conclude the run. Upon returning to the main menu, Mask of the Red Death becomes available for purchase, featuring 255 health, +100% movement speed, +20% damage, and the evolved scythe weapon.
