Corruption measures how far Coen has slipped into his vampiric nature in The Blood of Dawnwalker, and it doubles as the progression system for his entire Vampirism tree. It does not climb from experience or skill points the way Swordmastery and Witchcraft do. It rises only when Coen drinks blood, which turns feeding into a core build decision rather than a background survival habit.
Quick answer: Drink blood with the Voracious Bite. Bite enemies mid-fight in Vrakhir form or feed on highlighted wildlife through Focus Mode, and drink Blood Vials you pick up. Each drink raises Corruption, and a “New Vampiric Powers Available” prompt tells you to visit a Shrine to unlock what opened up.

What Corruption unlocks in the Vampirism tree
Corruption sits next to your Health bar as a small icon with a number in it, and in Vrakhir form it appears in the bottom-left corner so you can read it without opening a menu. The higher it climbs, the more of the Vampirism tree becomes available. Where Witchcraft and Swordmastery open through Manuals and Skill Points, the vampiric side stays locked until Coen has actually consumed enough blood, so hoarding Skill Points does nothing for it.
There are two separate tracks feeding the system, and they gate different things.
| Track | Fills from | Icon | What it gates |
|---|---|---|---|
| Regular Corruption | Animal, human, and Vrakhir blood | Fanged mouth | All Vampirism Perks, plus Abilities marked with the fanged-mouth icon |
| Vrakhir track | Vrakhir blood only | Skull | Abilities marked with the skull icon |
Every blood type raises the regular Corruption level, but only Vrakhir blood also builds the skull-marked track. That means a skull-gated Ability will not move no matter how much animal or human blood you drink. Vrakhir blood comes from feeding on Vrakhir enemies or from finding it out in the world.

Coen gets the Voracious Bite the moment he first turns, and it cannot be removed from the Abilities Wheel because it is also his main way to heal in Vrakhir form. Every use of it that draws blood pushes Corruption up.
Note: Choosing not to drink blood is a valid path, but staying at low Corruption keeps the advanced vampiric perks locked and makes the game considerably harder.

Fastest way to farm Corruption
Clearing enemy camps at night is the most efficient method if you are committing to a Vampirism build. After dark you are already in Vrakhir form, so every kill becomes a chance to bite instead of just swing. You stack Corruption through fights you would be having anyway, rather than setting aside time to hunt animals.
Ambrus’ Blood Cellars are another strong source. When you clear one, you get a choice between destroying the blood or collecting it. Pick Collect Blood if you want Corruption. Coen gathers several Blood Vials, and collecting them does not stop you from wrecking the cellar afterward, so you still destroy it, still anger Ambrus, one of Brencis’ boyars, and walk away with the extra blood.
Hastened Corruption and Overfeeding
Some Vampirism Perks speed up how fast the meter fills rather than just paying off once it is high. Hastened Corruption is worth prioritizing early because it directly shortens how long the rest of the tree takes to open.
| Level | Effect |
|---|---|
| First level | +30% Corruption filling speed |
| Later levels | Adds Overfeeding: drinking blood at full Health grants a temporary bonus Health Segment plus a further +50% Corruption filling speed while you stay Overfed |

How to confirm a new perk is ready
Whenever either track crosses a threshold, you get a “New Vampiric Powers Available” notification. That message is your signal to head to a Shrine, which is where you spend your progression to learn perks and abilities. If the prompt has not appeared, the tier you want is still gated, and you need to feed more before it opens.
What high Corruption does to Coen
A high Corruption level grants access to new vampiric abilities, and those upgrades make boss fights and nighttime exploration noticeably easier. Nighttime powers are fueled by both Health and Corruption, so your strongest vampiric attacks cost vitality when you cast them. That forces you to weigh damage output against your remaining Health in the middle of a fight.
The trade-off reaches beyond combat. High Corruption aligns Coen with the path of vampirism and feeds branching story paths, which means the level you reach helps shape your ending. It also carries a risk around people. The deeper Coen sinks into corruption, the closer he is to becoming a full vampire, and that raises the chance of losing control around human allies. Deciding how much of the beast to embrace is the core tension the whole system is built around.
