If a Vampirism node says “Drink Vrakhir blood to learn,” ordinary feeding and extra Skill Points will not clear that specific requirement. You need the named Vrakhir-blood route shown by the node: a boss encounter, a blood vial, or a quest reward. After drinking the correct blood, return to the Vampirism tree and read the node again; its skull-marked gate should change, while any remaining displayed requirement still applies.
How to drink Vrakhir blood
- Already have a phial? Open your inventory, select the named blood phial and read its description. Use its displayed consume action; collecting the reward alone is not drinking it. Match the name to the power in the table below. Murohn's Blood is a different item.
- At the end of a boss fight? Choose the blood-drinking option when offered. This route uses the encounter's decision, rather than a bottle you must find afterward.
- After drinking: reopen the Vampirism tree and inspect the intended power. If it is now purchasable, meet the remaining requirements shown there. If the blood condition remains, recheck which blood you used.
Exact inventory shortcuts and controller buttons are unconfirmed here; follow the action displayed for the selected item.
Match the power before choosing a blood source
| Target power | Blood | Open the relevant route | Check after drinking |
|---|---|---|---|
| Scarlet Shield | Ambrus | Post-fight choice in The Gilded Gauntlet, or the Lost Blood phial | The blood restriction on Scarlet Shield changes |
| Shadowstorm | Bakir | Collect from the reliquary in Come Home, or follow Unsavoury Solutions | The correct phial was consumed; inspect any remaining condition |
| Blood Surge | Xanthe | Follow Cathedral Treasury Key, then inspect the Treasury phial | Blood requirement, purchase state and night-time equipment |
Choose the power first, then open its route. A post-boss drinking choice, collecting a phial and consuming it from inventory are different actions. The exact Treasury chest and later branch consequences remain unconfirmed; check that route’s limits before committing.
Looking for Piercing Shriek or Mesmerize?
ATH's five-blood comparison separates these two routes. It associates Piercing Shriek with Brencis blood through Taste of Power or the end of Our Rotten Roots, while Mesmerize comes from Lacra's blood during her late quest and relationship route.
| Power | Required quest action |
|---|---|
| Piercing Shriek | Secure Brencis blood in Taste of Power, or complete Our Rotten Roots. |
| Mandrake Ward | Accept the mandrake in The Night of Horrors. |
| Mesmerize | Follow Lacra’s romance scene, including drinking her blood. |
PowerPyx distinguishes the mandrake perk from the romance blood reward, unlike the earlier PC Gamer summary. Follow The Night of Horrors and Lacra’s relationship choices, then verify the named node.
Read the locked node before starting a hunt
- Open Character Development and select the unavailable Vampirism ability. Read its exact condition instead of assuming every locked vampire ability has the same solution.
- A requirement for Corruption means ordinary feeding is relevant. A requirement for Vrakhir blood is a separate gate, so keep looking for the named blood source rather than farming animals or people.
- Check whether the node also names a parent perk, Skill Point, time cost, or quest. Drinking Vrakhir blood can clear its own condition, but it does not erase every other requirement displayed on that node.
The practical check is the icon and wording in your own tree. Do not use a boss name from a guide as proof that it is the source for a different locked ability.
Keep ordinary Corruption separate from Vrakhir blood
- Use ordinary blood feeding to raise regular Corruption for the Vampirism path. Bandai Namco confirms that feeding and embracing Coen's vampiric nature unlocks progressively stronger vampire abilities.
- Treat Vrakhir blood as a specific acquisition requirement for skull-marked abilities. It can also raise Corruption, but a higher regular Corruption value does not by itself satisfy a node that still explicitly asks for Vrakhir blood.
- When the game shows a new Vampiric Powers notification, return to a Shrine or the development menu and inspect which nodes changed. This is more reliable than guessing from the blood source or the size of the meter.
Keeping the two checks apart prevents the usual dead end: repeatedly feeding to solve a requirement that actually asks for a named Vrakhir source.
If the missing requirement is ordinary Corruption
At night, enter Focus Mode, locate highlighted wildlife, approach and use the feeding prompt. Check the Corruption display afterward; gaining health alone is not the unlock check. ATH also reports that feeding at full health still increases Corruption.
For an Overfeed attempt, first inspect Hastened Corruption: your learned rank must include that effect. Feed at full vampiric health, then check whether the buff appears. If injured, restore health first. Exact rank costs and speed bonuses remain unconfirmed here.
ATH describes biting a living pack animal, retreating until combat ends, then returning. If trying this, check bite availability and combat state before repeating. Repeatability and efficiency in your version remain unconfirmed; do not plan around an unlimited loop.
For a documented quest route instead, follow Just a Bit More and read its blood-choice consequences before collecting anything. Neither ordinary feeding nor Overfeed substitutes for a skull-marked Vrakhir requirement.
Use the named-boss route when the choice appears
- PC Gamer identifies three major Vrakhir boss routes: Ambrus, Bakir, and Xanthe. Defeat the relevant boss, then choose the post-fight option to drink their blood when the game presents it. For the Ambrus route, use the Gilded Gauntlet poison-and-blood decision guide before you enter the duel.
- The cited guide associates Ambrus with Scarlet Shield, Bakir with Shadowstorm, and Xanthe with Blood Surge. Use this only to match a named ability you are pursuing; the current node and decision prompt remain the final check.
- Make a manual save before accepting a post-boss blood choice if you want to compare story outcomes. The decision can be consequential, so do not select it solely because the ability name looks useful.
The sources disagree on the last step: the earlier boss guide describes an immediate grant, while ATH's five-blood article says drinking removes the blood lock and level 1 still needs a Skill Point at a road shrine. Open the tree afterward and follow the remaining requirements shown by your current build; do not assume either route bypasses the purchase screen.
Look for vials and quest rewards when no boss choice is available
- Vrakhir blood can also appear in vials found through some nighttime Murohn dens and certain quest routes. PC Gamer names Xanthe's Recruiters in Tantari Woods and The Silts, plus Lost Blood in St. Tyna's Grove, as examples of these alternate sources.
- When you find a vial, read its in-game name and use prompt before consuming it. The source describes vials as working more like manuals: they can unlock a related power or improve one that is already available.
- Do not assume that every bottle of blood is Vrakhir blood. If it does not match the node's condition or the game does not present a corresponding progression change, return to the tree and use that requirement to choose your next route.
These sources are alternatives, not a checklist that every player must clear. Follow the unavailable node first; then use the journal, map, and current quest stage to determine whether the named source is accessible.
Blood Surge: check the Treasury phial route
The Svartrau unlock account places Phial of Xanthe’s Blood in a small chest upstairs in the Cathedral Treasury. Use the Treasury Key route, then check the phial’s name before consuming it. Afterward inspect Blood Surge at a shrine, meet its displayed purchase requirements and equip the learned ability for nighttime use. Picking up the phial is not the purchase. The exact chest and all later Xanthe branch effects remain unverified here.
Scarlet Shield: Ambrus blood alternatives
ATH reports an Ambrus blood phial through Just a Bit More, and also names Lost Blood as an alternate corpse-loot route. The direct route is defeating Ambrus in The Gilded Gauntlet and choosing to drink when that option appears. Verify the item or post-fight choice names Ambrus before using it, then check whether Scarlet Shield changed from blood-locked to purchasable or learned.
Shadowstorm: Bakir blood alternatives
ATH lists Come Home and Unsavoury Solutions as phial routes. It also describes a Bloodletter route that requires finishing the Leech Collector chain and destroying blood barrels at at least one camp before the boss appears; defeating Bakir in The Lunar Game is the direct boss alternative. These conditions are source-reported rather than firsthand tested here, so use the current journal and phial name as the acceptance check.
Confirm the ability after drinking
- Reopen the Vampirism tree immediately after the encounter or vial. Check whether the skull-marked restriction changed and whether the ability now shows as available, purchasable, or learned.
- If the node is purchasable rather than immediately granted, inspect its remaining Skill Point, parent-perk, or time condition before confirming. Bandai Namco states that Skill Points are shared among all trees and that improving abilities can require points and time.
- Test the ability only in its valid night-time vampire state, following the on-screen equip or use prompt. A successful unlock does not guarantee that an ability is usable in Human form during daytime.
Use the notification, node state, and current form as a three-part check. That tells you whether the problem is the blood source, another progression gate, or simply trying to use a vampire power at the wrong time.
Fix the two most common mistakes
| What you see | What to do next | What confirms progress |
|---|---|---|
| Feeding raises Corruption, but the node still says “Drink Vrakhir blood to learn” | Stop ordinary feeding for this requirement. Match the target power to its named blood source in the table above. | The named blood condition changes after the correct blood is consumed. |
| A blood phial is in your inventory, but the power is still locked | Select the phial, read its full name and use the displayed consume action. Collecting it alone is not enough. | Reopen the target node and check whether its blood restriction has cleared. |
| You drank blood and the ability is now purchasable rather than learned | Check the remaining requirements shown on the node before spending points or looking for another phial. | The node shows the ability as learned after its remaining conditions are met. |
| The learned power will not work during daytime | Check your current form and the ability's nighttime equip/use prompt. | Test it in its valid vampire state rather than treating daytime failure as a missing blood unlock. |
| Your item is named Murohn's Blood | Read its restorative description; do not count it as the named Vrakhir phial for your target power. | Verify the required blood name against the power table before choosing a route. |
If you are at a major boss during daytime and the game only offers a kill path, do not assume you can still take the blood outcome. The cited ending guide reports that the choice to drink specific Vrakhir bosses is unavailable in the daytime fight path. Follow the live quest decision and consider a save before any choice you may want to revisit.
Empty Murohn lair: check this marker’s conditions
For a moon-marked lair, ATH describes using a shrine to advance to Moonrise, then returning. Check the time prompt first. Also check whether that particular lair is already cleared; several sites share the name. This is not a universal requirement for every quest encounter involving Murohn.
After the fight, inspect the corpse and nearby containers. The source describes Murohn’s Blood as a vampire-health restorative. Read the actual bottle before using it: that name alone does not satisfy a named ability’s blood requirement. For a documented quest vial, compare Lost Blood; for combat, use Murohn response steps.
