Ruxandra is the Sangrael vampire lair's alchemist. She treats vampirism as a chemical and biological system, and her route develops as your Vampire stat rises.

Finding Ruxandra

Ruxandra is always present in the Vampire Laboratory. From the Vampire Lair's main room, choose Vampire Laboratory.

There are two ways into the lair:

Dungeon route

Dungeon Floor 23 uses a special Vampire Castle layout. Stepping onto its Castle tile transfers you to the Vampire Lair. The lair's Return to Dungeon portal returns you to the stored Floor 23 position and map.

This route does not require Story Beat 61.

Story route

Complete Story Beat 61: A Vampire's Proposal. It triggers at the City Library from 20:00-22:00 after Story Beat 60. Completion unlocks the route:

City Library → Library Basement → Dark Corridor → Vampire Lair → Vampire Laboratory

This gives you a convenient present-era entrance without navigating Floor 23 again. See the Complete Story Beats Guide for the full prerequisite chain.

First Meeting

Entering the Vampire Laboratory for the first time automatically triggers Magistra Ruxandra.

Reward Amount
Base Ruxandra relationship +5
Caring response +3
Funny response +2
Flirty response +3

The best introduction therefore awards +8 relationship.

Relationship Mechanics

Ruxandra uses the universal relationship stages, but her implemented personal content is based mainly on the Vampire stat rather than relationship-stage gates.

Favorite checks

Favorite Threshold
Vampire 50
Mystic 80
Intelligence 95
Special skill Alchemy

These checks interact with the universal relationship-point modifier system. Ruxandra is Evil-aligned, so your current alignment axis can also alter relationship gains.

Repeatable action

Action Requirement Time Base gain Limit
Talk to Ruxandra Stranger+ 20 min +1 5/day

She has no favorite gift or dedicated gift action in the current implementation. She also has no current heart-to-heart, date, apartment visit, resort route, brothel-worker route, or Soul Stone bonding action.

Vampire Lore Route

Ruxandra's six lore scenes trigger automatically in the Laboratory. They must be completed in order.

Order Vampire required Plot Base reward Best choice bonus
1 10 Blood As Data +5 +3
2 20 The Obedient Prison +5 +3
3 30 The Negotiating Body +5 +3
4 40 Sunlight Is An Insult +5 +3
5 50 The Vanishing Problem +5 +3
6 60 The Second Nutrient +5 +3

For each scene, the nice and flirty choices are both registered at +3; the funny choice is +2. A best-choice completion awards +8 Ruxandra relationship per lore scene, or +48 across all six.

If you already have a high Vampire stat when you first meet her, only the next eligible scene will trigger at a time. Leave and re-enter the Laboratory to advance through the chain.

The Causal Window

Ruxandra has one cross-character plot with Torea.

Requirement Value
Location Vampire Laboratory
Ruxandra prerequisite Magistra Ruxandra introduction complete
Torea relationship Acquaintance+
Trigger Automatic, once
Base rewards +8 Ruxandra, +5 Torea

The choices distribute additional points between Ruxandra and Torea. This plot is independent of the six-step lore order; it does not require a particular Vampire threshold.

Blood Orbs

Blood Orbs have two competing uses:

  1. Use one from inventory: gain +1 base Vampire, up to 999, and fully restore Health, Energy, Calm, and Satiation.
  2. Spend them at Blood Alchemy: buy permanent artifacts or repeatable upgrades.

Because the shop itself requires effective Vampire 25, early Orbs may need to be consumed to reach the unlock. After that, decide whether the full restore and Vampire point are more valuable than saving toward an artifact.

Reliable farming information

  • Vampire enemies on Dungeon Floors 21-25 have a 15% Blood Orb drop roll after victory unless their data marks a guaranteed drop.
  • Blood Orb drops are separate from the normal pickaxe drop roll.
  • Vampire-themed random scenarios on Floors 21-25 can award, trade, consume, or otherwise involve Blood Orbs.
  • The Goblin Blood Orb scenario offers one Blood Orb for 5 Dragon Coins.
  • Some external reward systems can grant Orbs, but dungeon combat is the repeatable baseline source.

The dungeon's vampire-scenario priority check has a 50% chance to select from its vampire-specific scenario pool on Floors 21-25 when a random scenario fires. Anti-repeat tracking prevents the same small subset from appearing continuously.

Blood Alchemy Shop

The Blood Alchemy action appears in the Vampire Laboratory at effective Vampire 25. Opening it costs no time or money. Every shop item currently has the same Vampire 25 visibility requirement.

One-time artifacts

Item Blood Orbs Exact current effect
Vampire Fangs 55 Physical Attack, Quick Attack, Stormslash, and Power Strike have a 15% proc that bypasses enemy defense and adds Vampire-based damage. Vampirism raises the proc to 18% and strengthens the damage roll.
Hypnotic Gaze 50 Adds +10 percentage points to Sleep success after floor resistance; raises the normal Hypnotic-Gaze cap and raises base boss Sleep chance from 13% to 20%.
Nocturnal Cloak 50 Adds +1 effective armor level for damage reduction.
Eye of Batman 60 Adds +50 maximum Health, +50 maximum Energy, and +50 maximum Calm.
Draculas Ring 70 Adds +1 to the maximum relationship-point roll when your alignment axis matches the NPC's.
Vampire Grimoire 80 Offensive magic has a 15% proc to bypass enemy damage reduction, resistance, absorption, and strong-element resistance while preserving weakness bonuses; Vampirism raises the proc to 18% and strengthens its Vampire damage.

Buying all six unique artifacts costs 365 Blood Orbs. Owned artifacts remain owned and cannot be repurchased.

The in-game key is spelled Draculas Ring without an apostrophe; that exact spelling matters in save data and effect checks.

Repeatable refinements

Item Blood Orbs Requirement Exact current effect
Blood Exchange 10 Vampire 25 Permanently adds +1 maximum Energy.
Crimson Grail 20 Vampire 25 and own Elemental Stone Adds +1 Elemental Stone level.

Both refinements can be purchased repeatedly. Crimson Grail is hidden until the Elemental Stone is in your key items, and it raises the Stone's level without consuming it.

Artifact Buying Priorities

There is no universal best order, but these routes minimize wasted Orbs:

General-purpose build

  1. Eye of Batman for +50 to all three main combat pools.
  2. Nocturnal Cloak for always-on physical damage reduction.
  3. Choose Fangs or Grimoire based on your main offense.
  4. Add Hypnotic Gaze if Sleep is part of your control plan.

Physical build

  1. Vampire Fangs
  2. Eye of Batman
  3. Nocturnal Cloak
  4. Hypnotic Gaze or Draculas Ring to taste
  5. Vampire Grimoire last if you rarely cast offensive magic

Magic build

  1. Vampire Grimoire
  2. Hypnotic Gaze if you use Sleep
  3. Eye of Batman
  4. Nocturnal Cloak
  5. Vampire Fangs when physical backup attacks become relevant

Relationship-focused build

Draculas Ring only improves the top end of a relationship gain when your alignment axis matches the NPC's. It is valuable across many characters if you maintain a stable Good, Neutral, or Evil axis, but it does nothing while the alignment system treats you as Unaligned and does not soften opposite-alignment penalties.

  1. Reach the vampire depths and enter the Floor 23 castle.
  2. Meet Ruxandra in the Laboratory and choose Caring or Flirty for the best introduction bonus.
  3. Farm Blood Orbs from vampire enemies on Floors 21-25.
  4. Consume enough Orbs to reach effective Vampire 25 if necessary; remember that every consumed Orb is one less shop currency.
  5. Re-enter the Laboratory at Vampire 10 and 20 to clear the first two lore scenes.
  6. At Vampire 25, buy the artifacts most useful to your build.
  7. Continue the lore chain at Vampire 30, 40, 50, and 60.
  8. Raise Torea to Acquaintance and enter the Laboratory for The Causal Window.
  9. Complete Story Beat 61 when available to unlock the convenient City Library route.
  10. After buying the unique artifacts you want, direct surplus Orbs into Blood Exchange or Crimson Grail.

Troubleshooting

Ruxandra is not in the laboratory

She is scheduled there all day, every day. Confirm that you are in Vampire Laboratory, not Carmilla's Chamber or the Vampire Lounge. From the main lair, choose the Laboratory travel action.

The Floor 23 castle did not remain as a map shortcut

The floor route returns you to the stored dungeon tile through the lair portal. Story Beat 61 separately unlocks a permanent present-era route through the City Library basement.

Blood Alchemy is missing

The action requires effective Vampire 25. It does not require Ruxandra relationship progress or completion of a particular lore scene.

Crimson Grail is missing

You must be Vampire 25 and already own the Elemental Stone.

A lore scene will not trigger

  • Complete Ruxandra's introduction.
  • Reach the required Vampire value.
  • Complete the previous lore scene.
  • Leave and re-enter the Vampire Laboratory after another automatic plot finishes.

I used all my Blood Orbs raising Vampire

This is not a dead end. Continue fighting vampire enemies on Floors 21-25 and explore their scenario tiles. The shop is designed around repeatable Orb acquisition.

Current Content Boundary

The Second Nutrient at Vampire 60 is Ruxandra's current final personal lore scene. Relationship points can continue increasing through daily talks and universal modifiers, but no higher-stage Ruxandra romance scene, heart-to-heart, date, or apartment content is currently registered.
