Clock Tower pressure-plate boss. Drops the King's Gate relic. Killing him as Soma Cruz unlocks Yoko Belnades.
notasuccubusAbaddon is a Castlevania crossover boss in the Ode to Castlevania DLC. He is a contact-damage pressure-plate boss with 240 base HP scaling by player level, no projectile attacks, and a generous suite of resistances.
Abaddon is a Castlevania crossover boss added to Vampire Survivors on October 31, 2024. He shipped as part of the Ode to Castlevania DLC, the fifth and largest expansion the game has shipped.
He occupies bestiary slot 322 and is classified as a normal Ode to Castlevania enemy with the HP x Level skill. That skill multiplies his health pool by the player's character level at the moment he spawns.
His base health value of 240 is one of the lower numbers among the gate-key bosses. Once the multiplier applies, a level-50 character fights an Abaddon with 12,000 effective HP, while a level-100 mage faces one with 24,000.
The character originates from Castlevania: Dawn of Sorrow. He was the penultimate boss of The Abyss, a man-locust dressed like an orchestra conductor who summoned swarms with sweeping baton motions.
The Vampire Survivors version reuses the sprite directly but strips away the locust-summoning attack pattern. According to the Ars Gouda bestiary entry and confirmed enemy data on the wiki, this Abaddon has no projectile attack at all.
He is a contact-damage boss with knockback immunity and a generous suite of resistances. Mechanically he behaves like a tankier version of a standard Ode to Castlevania boss spawn.
He walks toward the player at 140 movespeed and deals 10 damage on touch. He cannot be frozen reliably, ignores knockback entirely, and resists most debuff effects. The fight is structured around survival and DPS, not dodging. Builds that already cleared 
Eligor or 
Galamoth will recognise the shape of the encounter.
| Stat | Value | What It Means |
|---|---|---|
| Bestiary # | 322 | Position in the in-game Ars Gouda bestiary, between Treant (321) and Menace (323) |
| Internal ID | TP_BOSS_ABBADON | The TP prefix is the data label for Tower-area Pressure-plate bosses |
| HP (base) | 240 | Multiplied by player level at the instant of spawn, locked thereafter |
| Power | 10 | Damage dealt on contact, before Armor reduction |
| Move Speed | 140 | Same as a standard wave enemy, faster than most gate bosses |
| Knockback Max | 0 (0) | Fully knockback immune, items like Stone Mask provide no displacement |
| Freeze Resistance | 1.1 | Requires Freeze chance above 1.1 to actually freeze him, most builds will not reach this |
| Rosary Resistant | Yes | Rosary cannot one-shot him through screen clear |
| Debuff Resistant | Yes | Curse, Defang, and similar debuffs do not apply |
| Defang Resistant | Yes | Cannot have his damage reduced by Defang procs |
| XP Drop | 3 | Modest experience reward, intended as a milestone not a farm target |
The Castlevania Wiki and most search aggregators use Abaddon (Hebrew origin, meaning "destroyer"). The Weirdgloop Vampire Survivors wiki uses Abbadon, which appears to be a spelling variant carried into the game data.
Searching the wiki for the spelling most players type returns a redirect or no result. As of April 2026, the canonical wiki page lives at the Abbadon spelling.
Abaddon spawns in an enclosed northern room of the Clock Tower biome, past the Zephyr rune. The room is gated behind the Capra Gate. Step on the skull pressure plate to summon him.
Abaddon does not appear on a wave timer like 
Malphas, 
Death, or the Reaper. He is a pressure-plate boss, summoned only when a specific player walks over the skull-symbol rune in his enclosed room.
That room sits behind the Zephyr rune, in the northern arm of the Clock Tower biome. The room is accessible only after the Capra Gate is open.
The walk in matters because Ode to Castlevania is a single connected map. Upstream content has to be cleared first.
Below is the route from a fresh run with no warp rooms unlocked. Players with the Capra Gate already active can skip to step 4.
Giant Bat to claim the Stallion Gate. This unlocks the first warp room and lets Heart Refresh items start dropping.
Zephyr rune, which drops the Gale Force weapon when defeated.One quirk worth knowing: the Clock Tower also contains the Stella and Loretta rune, just south of Abaddon's position. Death's rune sits there too, accessible only with Richter Belmont. Stacking these into one trip is possible on an unlock-all run. Abaddon is the only one of the three that progresses the gate chain.
Cast notasuccubus in the Forbidden Scrolls of Morbane menu to unlock Yoko Belnades instantly. The spell skips the achievement and does not drop the King's Gate relic.
Forbidden Scrolls ShortcutThe Soma + Abaddon path can be skipped entirely by casting notasuccubus in the Forbidden Scrolls of Morbane menu. This unlocks Yoko Belnades immediately, with the same starting Fulgur spell and Tragic Princess Arcana.
The tradeoff: the achievement that the boss-kill path grants is not earned. Abaddon still has to be defeated separately to add the King's Gate relic to the collection.
The spell name is a Castlevania: Dawn of Sorrow reference. In that game, Succubus enemies disguised themselves as Yoko before attacking Soma in the underground caverns.
Casting "notasuccubus" is essentially Soma confirming this Yoko is real. Players who care about lore tend to do the Abaddon kill first and use the spell only as a safety net.
The spell shortcut does not unlock 
Soma Cruz himself. Soma comes from defeating 
Gergoth as Julius Belmont, or casting the separate technicallynotavampire spell. Both the boss-kill chain and the spell list are catalogued in the Forbidden Box spell menu reference.
Abaddon drops the King's Gate relic, the fourth of six Gate Keys in Ode to Castlevania. The pickup unlocks a Clock Tower warp room, opens the King's Gate door, and adds Neutron Bombs to the random pickup pool.
Defeating Abaddon causes him to drop a guaranteed relic chest containing the King's Gate. This is the fourth of six total Gate Keys in Ode to Castlevania.
The standard progression order is: Stallion, Scorpion, Capra, King's, Serpent, Beast. Picking up the relic triggers three things at once.
| Effect | What Unlocks | Why It Matters |
|---|---|---|
| Warp Room | Mid-Clock Tower teleporter | Teleport to the room just east of the Abaddon arena at run start, no walk-up required |
| Item Pool | Neutron Bombs drops enabled | A new high-damage AoE pickup begins appearing in light sources after the gate is open |
| Map Access | King's Gate door opens permanently | Path to the upper Clock Tower and the routes leading to Doppelganger and the final tower section |
The Neutron Bombs unlock is the biggest practical payoff. Until this gate is cracked, the bombs do not appear in the random pickup pool at all.
That means any character building toward an explosive-heavy setup is gated by Abaddon. The full list of relics, including the other five Gate Keys, sits in the complete Vampire Survivors relics catalogue with the optimal collection order.
Soma Cruz needs Hand Grenade evolved into The RPG, plus stacked Area passives. Soul Steal triggers automatically on fatal damage as a built-in revive. Run him with Capra Gate active and warp directly into the Clock Tower.
The combined unlock chain is the reason most players come to this fight. Yoko requires playing as Soma Cruz, walking to the Abaddon plate, and finishing him off.
Soma is not a beginner character. He starts with the Hand Grenade weapon and a passive set focused on coin economy rather than survival.
Soma himself is a separate unlock. Earn him by defeating Gergoth as Julius Belmont (pictured) inside the Library biome, or use the technicallynotavampire spell to skip the boss kill.
| Stat or Effect | Value |
|---|---|
| Starting Weapon | Hand Grenade (evolves to The RPG with max Candelabrador) |
| Move Speed | +20% |
| Greed | +50% |
| Reroll / Skip / Banish | +5 each |
| Per-Level Growth | +1% Might per level (uncapped) |
| Health Drain Immunity | Yes (shared with vampire characters despite Soma not being one) |
| Soul Steal Trigger | Once per life, on fatal damage, screen-wide damage that converts enemies to hearts |
Soma's 
Soul Steal revival is the safety net that makes the Abaddon walk-up forgiving. The optimal opener is Hand Grenade to max early, then Candelabrador to evolve into The RPG by minute 10.
The Capra Gate warp is the fastest route to the Clock Tower with at least 30 minutes of run time remaining. Area items should stack aggressively because The RPG's damage output is gated almost entirely by AoE size.
Health-drain combinations like Pummarola plus a Garlic-build Soul Eater are wasted slots. Soma's drain immunity is a hard immunity, not a percent reduction, so the drain ticks do nothing.
Better picks for those slots: Spinach for raw Might, or Empty Tome for cooldown reduction. By the time Abaddon spawns, a player at level 80 to 110 should have a stat pool that can handle 30,000-plus effective HP.
Soul Steal InsuranceSoma's once-per-life Soul Steal trigger fires automatically when he takes fatal damage. The screen-wide hit converts surrounding enemies into hearts, which restore HP on pickup.
In an Abaddon fight where DPS is borderline, taking the hit deliberately is a viable backup plan: the screen-wide damage often closes the kill, and the heart drops top up health for the post-fight walk back.
Yoko starts with Fulgur (evolves to Tenebris Tonitrus with max Duplicator) plus the Tragic Princess (III) Arcana that reduces cooldowns while moving. +40% Move Speed makes her one of the fastest characters in the game.
Yoko Belnades is the Soma + Abaddon unlock payoff. She is a high-mobility witch character whose entire kit pivots around movement.
Her starting weapon is the 
Fulgur, an azure magic circle that teleports between screen edges. Her starting Arcana is Tragic Princess (III), which reduces the cooldown of certain weapons whenever the player is moving.
| Attribute | Value |
|---|---|
| Starting Weapon | Fulgur (evolves to Tenebris Tonitrus with max Duplicator) |
| Starting Arcana | Tragic Princess (III) |
| Move Speed | +40% |
| Speed (Projectile) | +40% |
| Magnet | +50% |
| Reroll / Skip / Banish | +10 each |
| Pickup Bonus | Can find special Castlevania pickups (Wall Chicken, etc.) from light sources |
The Tragic Princess Arcana is the under-discussed half of Yoko's kit. It reduces cooldowns on Garlic, Soul Eater, Santa Water, La Borra, Lightning Ring, Thunder Loop, Santa Javelin, Seraphic Cry, Carrello, Fulgur, Tenebris Tonitrus, and Keremet Bubbles whenever the player is in motion.
The faster the player moves, the larger the cooldown reduction. Yoko's +40% Move Speed feeds this directly.
Practical implication: Yoko is one of the only characters where Wings becomes a near-mandatory pickup. Move Speed becomes a damage stat, not just a positioning tool.
The mobility-driven cooldown stack pairs naturally with Limit Break weapons. The Seventh Trumpet relic and its Limit Break unlocks push the Arcana further by letting Fulgur and Tenebris Tonitrus level past their normal cap.
Abaddon is a Hebrew word meaning "destroyer." His Castlevania origin is Dawn of Sorrow, where he summoned locust swarms as the penultimate boss of The Abyss. The Vampire Survivors version drops the locust attack pattern.
The Ars Gouda bestiary entry for Abaddon describes him as a swarm-summoning conductor. The text calls out the orchestra-leader pose carried over from Castlevania: Dawn of Sorrow.
The character's name comes from the Hebrew word avadon, meaning "perish" or transitively "destroy." He is referenced in the Book of Revelation as the angel of the abyss who commands a plague of locusts.
The Castlevania Wiki notes that Abaddon's in-game sprite differs from his original concept artwork in two ways. The official art shows him predominantly green with a scorpion-like tail.
The in-game and Vampire Survivors sprites depict him as predominantly blue with no tail. Series director Shutaro "Curry" Iida has stated in a Reddit AMA that Abaddon is his favorite Castlevania boss from a design standpoint.
Koji Igarashi has called him his favorite gameplay-wise because of the locust-dodging puzzle in Dawn of Sorrow.
Abaddon sits at #322 in the Ars Gouda book, between 
Treant (321) and 
Menace (323). Both flanking entries are also Ode to Castlevania pressure-plate bosses.
That makes the trio a natural sequence to clean up while filling out the bestiary. All three can be done on the same Soma run if the build can handle it, then a separate Richter run handles Death and the upper Clock Tower bosses.
There are 15 pressure-plate bosses in Ode to Castlevania, separate from the wave-timer bosses. Each drops either a Gate Key relic or a unique weapon. Abaddon is one of six Gate Key bosses.
Abaddon is one of fifteen pressure-plate-summoned bosses in Ode to Castlevania. That count is in addition to the wave-timer bosses like Malphas, Death, and the Reaper.
Each pressure-plate boss either drops a Gate Key relic that progresses the map, or drops a unique weapon. The neighbours along Abaddon's route are listed below.
| Boss | Location | Drop |
|---|---|---|
| Treant (#321) | South of King's Gate | Wood Carving Stone |
| Menace (#323) | Catacombs | Serpent Gate relic |
| Eligor | Dining Hall | Beast Gate relic |
| Galamoth | Past the Serpent Gate maze | Standard chest |
| Zephyr | Halfway up Clock Tower | Gale Force weapon |
 Beelzebub | Past the Capra Gate | Pile of Secrets relic |

| Date | Build | Change |
|---|---|---|
| 31 October 2024 | Ode to Castlevania DLC launch | Abaddon added to game at bestiary slot 322 with the boss kit and stats described above |
| 28 October 2025 | Update 1.14 (Ode expansion) | No direct Abaddon changes, but the broader DLC expansion added new characters and adventure content tied to the same map |
| 4 December 2025 | Steam beta 52172286R | Updated Ode to Castlevania enemy hitboxes, Abaddon included in the pass |
The December 2025 hitbox pass affected all Ode to Castlevania bosses, not just Abaddon. The wiki update history confirms Abaddon was included in the pass but does not specify the hitbox change shape.
Players running outranged-DPS builds against him on the current beta should expect the kill geometry to differ from the 1.13 release.
Abaddon's location in Vampire Survivors is the enclosed northern room in the Clock Tower biome of the Ode to Castlevania stage map. He spawns from a skull-symbol pressure plate that sits past the Zephyr rune, about halfway up the tower, and is only reachable after the Capra Gate is open.
Defeat Abaddon by stepping on his skull-symbol pressure plate to spawn him, then dealing damage with whatever build is active. He has no projectile attack in Vampire Survivors, only contact damage at 140 movespeed and 10 power, so the fight is a DPS race against his HP x Level scaling.
On the Ode to Castlevania map, Abaddon's room sits in the upper Clock Tower, north of the Zephyr rune. The fastest map route is to use the Capra Gate warp to skip the early stage walk, then head east into the Clock Tower and north past Zephyr into the enclosed pressure-plate room.
Walk into the enclosed Clock Tower room past the Zephyr rune and step on the skull-marked pressure plate in the center. There are no time gates and no character requirements for the spawn itself. The character requirement only applies to what unlocks when he dies.
He always drops the King's Gate relic, the fourth Gate Key in the standard Ode progression. Picking it up unlocks a Clock Tower warp room, opens the King's Gate door, and adds Neutron Bombs to the random pickup pool.
Killing Abaddon as Soma Cruz unlocks Yoko Belnades. The character requirement is a hard check tied to the boss death, not to who summoned him. If a different character lands the killing blow, the Yoko unlock does not trigger even if Soma is in a co-op party.
Yes. Casting notasuccubus in the Forbidden Scrolls of Morbane menu unlocks Yoko Belnades immediately, with no Abaddon fight required. Abaddon still has to be defeated separately for the King's Gate relic and the Neutron Bombs item pool unlock.
The Castlevania source material uses Abaddon with two D's, from the Hebrew word for destroyer. The Vampire Survivors wiki and game data use Abbadon with two B's, which appears to be a spelling variant carried into the game files. Most search traffic uses Abaddon.
