Code Vein 2: Blood Code Locations & Interactive Tracking Guide

Swap a Blood Code at any Mistle and your character changes fundamentally. Not just your stat numbers — the weapons you can carry without penalty, the passive Traits active on your build, and the Formae you can equip effectively all shift simultaneously.

Blood Codes are Code Vein 2's class system, and with 57 total spread across every map and story path, they're also one of the deepest progression layers in the game.

Every Code's acquisition point is included on our maps available via the Code Vein 2 interactive guide hub, including those tied to specific eras, timeline choices, and story endings.

What Blood Codes Control: Attributes, Burden, and Traits

Each Blood Code sets six base attributes — Strength, Dexterity, Mind, Willpower, Vitality, and Fortitude. These attributes do more than indicate combat power: they determine which weapons and Defensive Formae you can equip without triggering the Overburden penalty.

Every piece of equipment carries a Burden cost for specific stats. When your equipped gear's Burden exceeds your Blood Code's attribute value for that stat, the Overburden penalty applies — reducing your dodge speed, stamina regeneration, and combat effectiveness.

Managing Blood Codes is therefore as much about gear compatibility as raw stats.

Each Blood Code also carries three fixed Traits — passive bonuses that activate under specific conditions unique to that Code.

Unlike Gifts, which can be mastered and transferred to other Codes, Traits are locked to the Blood Code that carries them. Swapping to a different Code means losing access to its Traits until you equip it again.

Some Traits are universally valuable regardless of build — the Superbia: Lou line includes a Trait that prevents Overburden even when carrying equipment that would normally exceed your Burden limits, which makes it a strong support Code for heavy loadouts.

How the Bloodline System Works

Blood Codes are grouped into Bloodline families named after Latin theological concepts — Superbia (Pride), Patientia (Patience), Gula (Gluttony), Luxuria (Luxury), Acedia (Sloth) — each family reflecting the combat personality of its founding character.

Within each family, Codes advance through numbered tiers: Superbia Bloodline: Lou 1 unlocks at game start, Lou 2 is earned by maxing Lou 1's proficiency and speaking to Lou, Lou 3 follows the same chain, up to Lou 4.

Maxing a Code's proficiency means equipping it and defeating enemies — the Code advances through combat use, not a single interaction. Most Bloodline chains end at tier 2 or 3; the Lou and Noah lines are the longest at four tiers each.

Hero Blood Codes are a separate category. Defeating a Hero in one of the Timeline Shift Decision main quests drops their specific Blood Code: Josée the Blind Hero from defeating Josée at Josée's Outpost, One-Armed Hero Lyle from The Continent, Hero Holly the Reaper from The Continent, Hero Lyle from Pioneer Castle.

These are distinct from the Bloodline chain Codes and aren't upgradeable in the same way.

Timeline Shift Decisions and Branching Blood Codes

Several Blood Codes are tied directly to your choices in the time-travel system.

Timeline Shift Decisions — the missions where you decide whether to save or slay a Hero in the past — determine which version of that character's Code you receive. Some Codes exist exclusively on branching story paths and require multiple playthroughs to collect all variants.

Collecting every one of the 57 Blood Codes requires completing all story endings.

Our Main Quest guide documents which Timeline Shift Decisions trigger which Code variants.

57 Blood Codes Across All Maps

The largest concentration is in the MagMell Hub — where most Bloodline chain tiers are unlocked by speaking to NPCs after maxing proficiency — and on The Continent, where several story-earned Codes are given automatically during the major Era missions.

MagMell Island provides the earliest Codes, including the starting Lou Code and the post-Bond Guardian's Heart.

The furthest Code in the guide is Luxuria Bloodline: Camilo, earned in the time-travel area at Sanatorium 2277 - The Present after defeating the Transformed Patient.
