Darkanas are not "dark mirror" arcanas the way most players assume. Per the official patch notes for v1.11, "the only difference between Arcanas and Darkanas is their theme; functionally they are exactly the same." The 12 Darkanas just appear in the same Arcana Chest pool as base arcanas, share Roman numerals with their thematic counterparts, and stack with regular arcanas in the same run.
Two-step unlock: type forbiddenbox in the Secrets menu to access Room 1665, then complete the 1665-kill challenge to collect the Darkasso relic. The Darkasso unlocks the Darkana system plus the first darkana, Moonlight Bolero (VI). Other darkanas unlock via specific character/condition combos.
Per the official Vampire Survivors Wiki, Room 1665 is the ONLY hidden stage in the game where the spell unlock IS the canonical method. Most spell shortcuts bypass an alternative unlock path; the forbiddenbox spell is the intended unlock for Room 1665, and this is reflected in the achievement description which explicitly tells players to "Dare to cast the spell forbiddenbox."
| Step | Action |
|---|---|
| 1 | Open the Secrets menu (after collecting the Forbidden Scrolls of Morbane in The Bone Zone, OR temporarily by clicking the Yellow Sign relic icon 7 times in the Collection) |
| 2 | Type forbiddenbox letter by letter (each letter must be typed within 30 seconds of the last). The spell unlocks Room 1665 and the EXTRA: Room 1665 achievement |
| 3 | Start a Room 1665 run. Defeat 1665 enemies to progress through the 16 rooms. The Darkasso relic sits in the center of the final room |
| 4 | Walk into the Darkasso. Collection animation plays automatically. Moonlight Bolero (VI) is granted as the first free Darkana |
| 5 | Spell shortcut: type darkassami in the Secrets menu to skip Room 1665 entirely; grants Darkasso + Moonlight Bolero (VI) immediately |
Room 1665 is structured as 16 sealed chambers. Each room unlocks at kill milestones: 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, and finally 1665 (NOT 1500). All modifiers except Arcanas and Limit Break are disabled at the start. The stage gets progressively darker until the final room lights up entirely on opening.
Per the official wiki, Room 1665 is uniquely structured. The player starts in a small locked chamber with limited movement space. There is no arcana selection at run start. Defeating 100 enemies opens the next room. Pair with our Curse stat reference for density math (although Curse is NOT recommended in Room 1665). Each subsequent room unlocks at the next 100-kill milestone EXCEPT the final room, which unlocks at 1665 kills instead of 1500. The stage explicitly subverts the expectation that "Room 1665" refers to a year or location and instead refers to the unlock condition.
| Character | Why It Works |
|---|---|
| Miang Moonspell | High base damage; community testing identifies her as the easiest character for the Darkasso run |
| Queen Sigma | Maxed stats and weapon flexibility; can adapt to whatever weapons spawn from chests |
| Christine Davain | Pentagram starter screen-clears every chamber transition |
| Avatar Infernas | Heart of Fire (XIX) baked-in arcana provides AOE damage even without arcana picks |
Per the official wiki and community guides, the recommended Room 1665 loadout includes Pummarola, Garlic, Runetracer, Armor, Pentacle, and Crown. The combination provides recovery sustain (Pummarola), constant AOE damage (Garlic, Runetracer), defensive scaling (Armor, Pentacle), and accelerated leveling (Crown) for fast room transitions. Boss enemies in Room 1665 have less health than non-boss enemies, so stacking Curse to spawn more enemies is counterproductive. See our bosses guide for general boss-fighting strategy.

Moonlight BoleroHidden AnathemaHail Future| Tier | Darkanas | Why |
|---|---|---|
| S | Moonlight Bolero (VI), Hidden Anathema (III), Hail from the Future (X) | Universal value; drop multipliers and stat scaling |
| A | Crystal Cries (XII), Heir of Fate (XIX), Sapphire Mist (I) | Strong build enablers with specific synergies |
| B | Victorian Horror (XVIII), Call of a Mad Moon (XIII), Pale Diamond Incursion (V), Edge of the Earth (VIII), Wandering the Jet Black (XXI) | Situational; depend heavily on character or build pairing |
| C | Stake to Your Heart (0) | Niche; XP-locked builds only, like the Game Killer arcana |
VSDirect answer: Moonlight Bolero for chest farming and arcana stacking; Hidden Anathema for Gazebo or food-pickup-heavy stages.
Moonlight Bolero (VI) spawns an extra treasure boss every minute, which means a 30-minute run yields 30 extra bosses with chest drops. Some of these chests contain arcanas, weapons, or relics, so the darkana is the single most efficient method for stacking arcanas in a run beyond the standard 3. Hidden Anathema (III) is more situational; it requires food pickups (Floor Chicken, Wall Chicken, Sorbetto, Nduja Fritta Tanto) to scale, so its value is highest on The Coop, Lake Foscari, or stages where Gazebo-style food density is naturally high.
Each Darkana shares a Roman numeral with a corresponding base Arcana. The artwork on the cards depicts the same two figures, just thematically darker. Per the official wiki, this is the only confirmed relationship; the patch notes explicitly state Darkanas and Arcanas are functionally identical in mechanics.
| Roman Numeral | Arcana | Darkana |
|---|---|---|
| I |  Gemini | Sapphire Mist |
| VI | Sarabande of Healing | Moonlight Bolero |
| VIII |  Mad Groove | Edge of the Earth |
| XVIII |  Boogaloo of Illusions | Victorian Horror |
| XIX |  Heart of Fire | Heir of Fate |
Per the official wiki, the Darkana names reference Castlevania music tracks (mirroring the original Arcana naming convention). See our passive items hub for the full Castlevania-inspired item reference. For example, Hidden Anathema (III) references The Hidden Curse (Forest of Doom theme); Victorian Horror (XVIII) references Victorian Fear (City of Haze theme); Call of a Mad Moon (XIII) references Invitation of a Crazed Moon (Entrance theme), all from Castlevania: Portrait of Ruin.
Once the player has unlocked 23 or more total Arcanas + Darkanas combined, every Arcana Chest opens with 6 random options instead of 4 AND grants one free Reroll. The threshold requires unlocking at least one Darkana, since 22 base arcanas alone cannot reach 23.
Per the official wiki, the 23+ threshold is one of the most underrated mechanics in Vampire Survivors. The bonus options and free Reroll dramatically improve the odds of finding a desired arcana in a chest, especially when the player has 25+ unlocked arcanas. This is a significant practical reason to unlock at least one or two Darkanas beyond Moonlight Bolero, even for players who do not enjoy the Darkana mechanics themselves. Compare with our Empty Tome guide for the Cooldown stat scaling that compounds with Sapphire Mist.
| Total Arcanas Unlocked | Chest Options | Free Reroll |
|---|---|---|
| 1 to 22 (Arcanas only, no Darkanas) | 4 random uncollected | No (must spend Reroll stat) |
| 23+ (Darkanas required) | 6 random uncollected | Yes, one free Reroll per chest |
Picking Moonlight Bolero (VI) at run start triples the effective arcana pool because the extra treasure bosses drop chests that can contain more arcanas. Combine with Hidden Anathema (III) on food-rich stages and Hail from the Future (X) on level-up-heavy builds for compounding scaling.
| Build | Pick 1 (Start) | Pick 2 (11:00) | Pick 3 (21:00) |
|---|---|---|---|
| Arcana Stacker | Moonlight Bolero (VI) | Hidden Anathema (III) or Mad Groove (VIII) | Hail from the Future (X) or Sarabande (VI) |
| Stat Scaler | Hidden Anathema (III) | Hail from the Future (X) | Crystal Cries (XII) or Sarabande (VI) |
| Damage Maximize | Sapphire Mist (I) | Heir of Fate (XIX) or Heart of Fire (XIX) | Moonlight Bolero (VI) |
| Extreme No-Weapon | Victorian Horror (XVIII) | Sarabande of Healing (VI) | Awake (IV) or Hidden Anathema (III) |
Players new to the Darkana system run into these recurring problems:
There are 12 Darkanas total. They are numbered 0 (Stake to Your Heart), I (Sapphire Mist), III (Hidden Anathema), V (Pale Diamond Incursion), VI (Moonlight Bolero), VIII (Edge of the Earth), X (Hail from the Future), XII (Crystal Cries), XIII (Call of a Mad Moon), XVIII (Victorian Horror), XIX (Heir of Fate), and XXI (Wandering the Jet Black). Each Darkana shares a Roman numeral with a corresponding base Arcana.
Type forbiddenbox in the Secrets menu to unlock the Room 1665 stage. Then start a Room 1665 run and defeat 1665 enemies to progress through 16 sealed rooms. The Darkasso relic sits in the center of the final room. Walking near it triggers the auto-collect animation. Spell shortcut: type darkassami in the Secrets menu to skip Room 1665 entirely.
Per the v1.11 patch notes, Darkanas are functionally identical to Arcanas. The patch notes explicitly state that the only difference is theme. Darkanas appear in the same Arcana Chest pool, count toward the 23+ unlock threshold (which gives 6-card chests with free Reroll), and stack with regular arcanas in the same run with no special interaction rules.
Moonlight Bolero (VI) is universally S-tier because it spawns an extra treasure boss every minute, which means 30 extra bosses per 30-minute run. Many of these bosses drop Arcana Chests, weapons, or relics. Hidden Anathema (III) and Hail from the Future (X) round out the top three because they provide compounding stat scaling.
Per the official wiki, the stage has 16 sealed rooms. Each unlocks at a kill milestone (100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, and finally 1665, NOT 1500). The stage name reflects the unique 1665-kill threshold for the final room. The number is a thematic reference and the canonical unlock requirement, not a year or location.
Yes. Typing darkassami in the Secrets menu unlocks the Darkasso relic and Moonlight Bolero (VI) immediately. Per the official wiki's standard rule for spell shortcuts, the spell does NOT trigger the EXTRA: Darkasso achievement. Players chasing in-game 100% completion still need to manually complete Room 1665 with the forbiddenbox spell to register the achievement.
Each Darkana has its own unlock condition. Sapphire Mist (I) requires -85% Cooldown with Space Dude. Hidden Anathema (III) requires reaching Gazebo's stat cap. Hail from the Future (X) requires triggering Weird Souls Purifier with Santa Ladonna. Each unlock typically requires a specific character + condition combo. See the All 12 Darkanas table above for the complete list.
The 23+ threshold. Once the player has 23 or more total Arcanas + Darkanas combined, every Arcana Chest opens with 6 random options instead of 4 AND grants one free Reroll. Since 22 base arcanas alone cannot reach 23, unlocking at least one Darkana is required to access this dramatically improved chest experience for the rest of the playthrough.
Darkana mechanics, all 12 unlock conditions, Room 1665 stage layout, and the 23+ chest threshold cross-referenced against the official Vampire Survivors Wiki on Weirdgloop and the Vampire Survivors Fandom Wiki, including patch v1.11 release notes that introduced Darkanas and patch v1.14 Ante Chamber DLC notes that added Pale Diamond Incursion and Heir of Fate. In our experience, the wiki Arcanas page and Category:Darkanas page are the definitive single references for the full Darkana list and unlock conditions.
