Magistra Ruxandra Walkthrough and Blood Alchemy Guide
Spoiler warning: This guide covers the vampire depths, late-story vampire access, Ruxandra's lore scenes, Blood Orbs, and every current Blood Alchemy purchase.
This guide expands on Sh1n7's community-created Ruxandra wiki page, used under CC BY-SA 4.0. All requirements, prices, and effects below were rechecked against the current game source.

Overview

Magistra Ruxandra is the vampire laboratory's 260-year-old alchemist in the Present. Her current route contains an introduction, daily Talk, six sequential Vampire-stat encounters, The Causal Window with Torea, and a Blood Alchemy shop that exchanges Blood Orbs for permanent items and upgrades.
This walkthrough lists access, requirements, choices and mechanical rewards. The laboratory's major discoveries and personal story revelations are left to the game.
NB: The walkthrough sometimes refers to "effective" Vampire stat vs. raw Vampire stat (with or without bonus), but to this day, there's no Key Item or Potion buff that awards a Vampire stat bonus (9.8.5).

Quick Stats

Attribute Value
Age / era / alignment 260 / Present / Evil
Favorite relationship bonuses Vampire 50; Mystic 80; Intelligence 95
Special relationship skill Alchemy, doubles her adjusted affection base when learned
Location / schedule Vampire Laboratory; all day, every day
Talk 20 minutes; 1 base; five positive talks daily
Lore progression Effective Vampire 10 → 20 → 30 → 40 → 50 → 60
Blood Alchemy Effective Vampire 25; purchases use Blood Orbs
Ordinary gifts / romance actions None currently configured
Listed relationship rewards are base values. Favorite stats add bonuses when their thresholds are met, and the special relationship skill doubles the adjusted base before the shared random roll. Equipment, buffs and alignment can further change the final reward. Raising affection does not replace quest flags or earlier heart-to-hearts.
Her Alchemy relationship bonus does not mean she teaches Alchemy; no skill-teaching action is configured on her portrait.

Reach the Vampire Laboratory

Two routes reach the laboratory:
Route Requirements and directions
Infinity Dungeon entrance Reach floor 23 and interact with its castle tile to enter Vampire Lair; continue to Vampire Laboratory. This entrance does not require Story Beat 061
City Library passage Complete Story Beat 061, available at City Library, 8–10 PM, after Story Beat 060. Then travel City Library → Library Basement → Dark Corridor → Vampire Lair → Vampire Laboratory
The Dark Corridor action checks Story Beat 061 completion. Simply entering the Library Basement is insufficient to open that passage. The castle route is independent of that story flag and records your dungeon position; Return to Dungeon restores the saved floor and position.
These location transitions have zero configured game-time cost. Ruxandra's laboratory portrait is present at every hour once you can reach the room; it has no additional affection or daily schedule gate.

Suggested Progression

  1. Reach the Vampire Laboratory through either route. The automatic Magistra Ruxandra introduction completes once; Caring or Flirty gives 8 total base, versus Funny's 7.
  2. Use Talk to Ruxandra, up to five positive talks daily. Five talks cost 100 minutes for 5 base, before shared relationship bonuses.
  3. Raise your effective Vampire stat. After the introduction, revisit the laboratory for the six encounters at 10, 20, 30, 40, 50 and 60. Each requires the previous encounter complete.
  4. At effective Vampire 25, use the location action Ruxandra's Blood Alchemy. Carry enough unconsumed Blood Orbs for the desired purchase.
  5. After the introduction and Torea Acquaintance, return to the laboratory for The Causal Window. It is independent of the six lore thresholds and Ruxandra's affection stage.
Only one eligible automatic plot is selected on a location visit. If several are ready, leave and re-enter the laboratory to continue. Raising Ruxandra's affection alone does not satisfy a Vampire-stat requirement.

Daily Talk and Introduction

Interaction Requirements Cost Reward / repeat
Talk to Ruxandra Stranger; Vampire Laboratory, all day 20 minutes 1 base; five positive talks daily
Magistra Ruxandra First laboratory encounter No additional configured resource cost 5 fixed + Caring/Flirty 3 = 8 base; once
The introduction's Funny reply gives 5 fixed + 2 = 7 base. Ordinary Talk beyond the positive daily allowance can trigger the escalating annoyance penalty, up to −5 affection. Counters reset on the game day change.
Ruxandra has no ordinary gift action. Shop purchases, inventory Blood Orb use and lore stat requirements are separate from ordinary affection.

Six Vampire-Stat Encounters

These automatic laboratory encounters complete once each, at any hour. The requirement reads your effective Vampire value, including modifiers. Every encounter requires the introduction, and encounters after the first also require the immediately preceding encounter complete.
Encounter Effective Vampire required Preceding encounter Best Ruxandra base
Blood As Data 10 Introduction 8
The Obedient Prison 20 Blood As Data 8
The Negotiating Body 30 The Obedient Prison 8
Sunlight Is An Insult 40 The Negotiating Body 8
The Vanishing Problem 50 Sunlight Is An Insult 8
The Second Nutrient 60 The Vanishing Problem 8
For every row, choose Nice or Flirty: 3 choice + 5 fixed = 8 base. Funny gives 2 + 5 = 7. The six best replies total 48 base before shared relationship bonuses. There is no configured Ruxandra affection-stage prerequisite, additional clock window, cash/energy cost, stat increase, player Erotic XP or NPC intimacy XP reward for these scenes.
Having Vampire 60 immediately does not skip the chain. Complete the introduction and each earlier encounter, then re-enter for the next eligible scene.

The Causal Window with Torea

Visit the laboratory after Magistra Ruxandra and Torea Acquaintance. This shared encounter completes once, at any hour, without a Ruxandra affection-stage or Vampire-stat prerequisite. Its fixed rewards are 8 Ruxandra / 5 Torea base, plus two choices.
Decision Reply Added Ruxandra / Torea base
First Caring: “Tell me the truth. I will keep up as best I can.” 3 / 1
First Funny: “If I am kicking beakers, I should know which ones explode.” 2 / 2
First Flirty: “For you, Magistra, I can pretend to understand beautifully.” 2 / 3
Second “Bellavia is a person, not just proof.” 2 / 3
Second “I am not sure I enjoy being a math injury.” 3 / 2
Second “Impossible near Torea sounds like a dangerous compliment.” 1 / 3
To maximize Ruxandra, choose Caring → math injury for 14 Ruxandra / 8 Torea total base. To maximize Torea, choose Flirty → person for 12 Ruxandra / 11 Torea, or Flirty → dangerous compliment for 11 / 11. No additional scene time, cash, Energy, Calm or intimacy XP is configured. The scene's explanations and outcomes are omitted here.

Blood Alchemy Shop

For the dedicated shop guide, illustrated interface, purchase instructions, and buying advice, see Ruxandra's Alchemy Shop.
Use Ruxandra's Blood Alchemy in the Vampire Laboratory with effective Vampire 25 or higher. The shop does not require the introduction, a lore encounter, Ruxandra affection, Alchemy skill or a separate supporter flag. Opening it takes zero game time and spends nothing.
All eight entries require effective Vampire 25. Purchases consume the listed Blood Orbs from consumable inventory, with no configured cash, time, Energy, Calm, affection or intimacy XP reward/cost.

Six permanent key items

Each item can be bought once. An owned item cannot be purchased again. Their total cost is 365 Blood Orbs.
Item Blood Orbs Current effect
Vampire Fangs 55 Eligible physical attacks have a 15% vampirism proc that bypasses defense and adds Vampire-based damage; Vampirism skill raises the chance to 18% and strengthens the bonus
Hypnotic Gaze 50 Adds 10 percentage points to ordinary Sleep after floor resistance; its normal success cap rises 70% → 75%. Against bosses, base success rises 13% → 20%, before other modifiers; Sleep immunity still prevents it
Nocturnal Cloak 50 +1 effective armor level for damage reduction
Eye of Batman 60 +50 maximum Health, Energy and Calm each
Draculas Ring 70 When the NPC's alignment matches yours, adds +1 to the maximum of the relationship gain roll; this is not a guaranteed flat affection point on every interaction
Vampire Grimoire 80 Offensive magic has a 15% vampirism proc that bypasses magic defenses and adds Vampire-based damage; 18% with Vampirism skill, with a stronger bonus
Vampire Fangs applies to the ordinary physical attack, Quick Attack, Storm Slash and Power Strike. Vampire Grimoire applies to offensive magic; it is not a Sleep/support-spell enhancement. Its proc bypasses the enemy's floor defense/guard and resistance/absorption or strong-element reduction, while favorable elemental weakness still counts.
The shop sells these items, not the Vampirism skill itself. You do not need Vampirism to buy or benefit from Fangs or Grimoire at their ordinary 15% chance. Hypnotic Gaze and Sleep Spores can both contribute to Sleep; enemy penalties and immunity still apply.

Two repeatable upgrades

Service Blood Orbs per use Requirement / result
Blood Exchange 10 Permanently +1 maximum Energy; repeatable
Crimson Grail 20 Must already own an Elemental Stone; +1 Stone level, repeatable
Crimson Grail is hidden without the Stone. It raises the existing Stone's level rather than creating or consuming a Stone. Blood Exchange raises the maximum; it does not include a configured current-Energy refill.

Obtain and Use Blood Orbs

Blood Orbs are both shop currency and a usable inventory consumable. Spending an orb at the shop does not apply its inventory-use effect.
Source / use Current behavior
Eligible vampire combat, dungeon floors 21–25 Victory has a 15% base chance to add one Blood Orb; drop-affix and Thieves Gloves bonuses can modify the chance, and a guaranteed-drop flag overrides the roll. No pickaxe is required
Goblin Blood Orb random encounter Trade 5 Dragon Coins for one orb, when the encounter appears
Goblin theft alternative Requires Sleight of Hand; the raw Rogue +20 value is checked against a 1–100 roll. Success gives one orb; failure costs 25 Health
Use Blood Orb from inventory Consumes one orb, raises raw Vampire +1 up to 999, and refills Health, Energy, Calm and Satiation to their current maximum values
Eligible combat enemies include the vampire, vampire boss, huntsman, acolyte, ripper, enforcer and stalker families and registered blood enemies. The combat drop's floor 21–25 condition still applies. Random dungeon encounters are not guaranteed on every tile or every visit.
To reach a stat gate, use or otherwise raise Vampire; to pay the shop, keep the required orbs unconsumed. Ruxandra's lore and shop check effective Vampire, whereas the inventory-use increase changes your raw Vampire stat.

Completion and Troubleshooting

  • Library route blocked: complete Story Beat 061; its starting window is City Library 8–10 PM after Story Beat 060. The floor-23 castle remains an independent entrance.
  • Ruxandra absent: reach Vampire Laboratory, rather than stopping in the Vampire Lair. Her laboratory schedule is all day.
  • Lore does not trigger: check introduction completion, effective Vampire, and the previous encounter; leave and re-enter after another eligible scene.
  • High affection does not unlock lore: the six gates use Vampire 10 / 20 / 30 / 40 / 50 / 60, without an ordinary relationship-stage substitute.
  • The Causal Window missing: check Torea Acquaintance and Ruxandra's introduction; the six-scene lore chain is not required.
  • Shop unavailable: check effective Vampire 25 and the laboratory's location actions.
  • Cannot afford a purchase: carry the specified number of Blood Orbs, not cash or Dragon Coins. Inventory use consumes orbs before they can be spent.
  • Crimson Grail missing: already own an Elemental Stone.
  • Unique item cannot be bought again: it remains owned; only Blood Exchange and Crimson Grail are repeatable.
Her implemented completion goals are the introduction, all six Vampire encounters, The Causal Window and the available alchemy services. No heart-to-heart, date, apartment, private movie, Kupie selection, venue invitation, worker recruitment, pregnancy route or NPC intimacy reward-image files are currently configured for Ruxandra.
