CODE VEIN II — Affinity Analysis Summary

→日本語版

Version: Based on data from v1.0.7.0 onward

Units: %pt = UI display value (each category's cap = 100%: Exploration cap of 40 pt, Story cap of 30 pt, Gifts cap of 30 pt), pt = internal value

Basic Structure

• Affinity is composed of three categories: Exploration, Story, and Gifts
• Internal cap per category: Exploration 40 pt / Story 30 pt / Gifts 30 pt (total 100 pt)
• Weapon Unlock: Total 72 pt or more required
• "Irreplaceable" Trophy: Total 100 pt (all caps)
• UI display: viewable at Mistletoe or Gifts screen. Shown to 1 decimal place, truncated (floor)
• Source files (v1.0.3 dump): DT_ClosenessEventData.uasset / DA_ClosenessSettings.uasset / DT_ShopLineup_Trade.uasset

■ Fastest Route to "Irreplaceable"

Recommended Character: Iris (definitively the fastest)

Reason

• Exploration: High probability of naturally capping at the point of the first Hero Josée defeat (kill enemies, defeat bosses, collect all objects)
• Story: 100% after 4 dedicated quests (aligns naturally with main story progression)
• Gifts: 30× Military Ration (4,500 Haze) or 179× Boiled Egg. Possible from the start

Chart

1. After [Talk to Iris], set her as Partner and keep using her throughout.
2. Exploration pt is heavily weighted toward enemy kills, and pt per kill scales with player level — progress at Lv1 while actively hunting enemies. Collect Haze at the same time.
3. Sunken City → Undead Forest: obtain first 2 Remnants (factors).
4. Once Corroded Scar Forward Base Two unlocks, buy 30× Military Ration and return to present-day MagMell to give them.
5. After defeating Hero Lyle, obtain Remnant in Corroded Scar.
6. Trophy unlocks upon completing the final Request. Can be achieved before heading to Insula Carcere.

Recommended Character: Valentin

Reason

• Exploration: Can use the Gorge Cave
• Story: 100% after 5 dedicated quests
• Gifts: 179× Boiled Egg. Possible from the start

Chart

1. Once the Free Exploration Era becomes accessible, start gifting
2. Sunken City, Corroded Scar, Frontier northwest: activate altar and cave Mistletoes
3. Fast-travel and defeat bosses
4. After defeating Hero Lyle, obtain Remnant in Corroded Scar.
5. Trophy unlocks upon completing the final Request. Can be achieved before heading to Insula Carcere.

■ Exploration Category

■ Conclusion

• Unlike before v1.0.7.0, the pt gain from killing regular enemies has increased significantly, making it fine to collect/activate objects with any character. In short: just kill lots of enemies. At Lv1, defeating 267 enemies gets you to 100%.

Example: 12 kills × 23 runs in the Ruins = 100%.

Example: 11 kills × 25 runs in the Gorge Cave = 100%.

Item Pickup

Apart from Treasure Chests and Yellow items, rarity makes no difference. Includes drops. Multiple items gained at once (e.g., Uncanny Stone ×2) still count as 1 action.

Map Objects

Enemy Kills (v1.0.7.0+)

Basic Mechanism

• All field enemies (= non-Named) give the same pt
• Enemies killed during enemy-vs-enemy combat also count as player kills and award pt (by design)

Derived by recording Δ% after killing a single normal mob, then extrapolating from the sequence; same method used for elite enemies.

Named (Boss) Kills:

Both types derived by measuring Δ% before and after each fight.

Level Scaling (Estimated)

• At Lv300, field enemy pt drops to a floor of 1/5 compared to Lv1
• Shape of the decay function (linear, exponential, etc.) is unknown
• Identifying the floor level requires intermediate level data (not yet collected)

Eras Available for Exploration

※: Affinity display is not shown, but Exploration pt still accumulates.

※2: Unlocked after defeating the 3 Revised Heroes.

※3: Escort period only. No Affinity, but this is the only time you can receive her Blood Code.

Accumulation Before Display Unlocks

■ Exploration Pt Farming

Past General Method

Location: Free Exploration Era — Undead Forest — Gorge Cave, 11 enemies just inside at the altar

Condition: Any Partner available in the Free Exploration Era

• Noah / Valentin / Josée / Lyle / Holly / Zenon / Craig / Lise

Chart

1. Upgrade Battle Axe: Idris' Pride as much as possible (fastest is probably +3)
2. Jump the fence and land directly behind the 6 enemies
3. Strike with Idris' Pride
4. Cancel immediately with forward roll and strike ×2

• ~30–40 seconds per run
• Average ~4.75%pt per run (0.375×11 + 0.125×5). Can go 0–100% in ~30 minutes

General Method

Location: Sunken City — Seized Substation area

Condition: None

Method: Repeatedly kill the 5 patrolling enemies

• Idris' Pride can be used, but be careful — there are 2 ranged enemies + 1 spear user

Location: Sunken City — Western Gatehouse Ruins

Condition: None

Method: Repeatedly kill the 7 enemies

Early-Game Method

Location: Present — MagMell Island — Near the Pier

Condition: Any Partner available in the Present

Method: Let enemies fight each other + kill the Moon Messenger yourself

• Doable at Lv1 with weakest gear
• Roughly 90–100 seconds per cycle in early game; can be shortened with upgraded weapons and buffs
• Moon Messenger: 3,220 Haze/kill; Regular mob: 184 Haze/kill
• Up to 4 enemies (only 1 can be directly triggered by the player)

■ Exploration Pt Tips

AFK Farming at MagMell Island Pier

How it works:
· A SE (Special Enemy) vs. 3 mobs fight triggers near the pier
· If you're nearby, Haze and pt from fallen mobs are added to the player (by design)
· Resting at Mistletoe repops enemies → combat restarts

Benefits?:
· Zero risk of player death
· Haze also accumulates simultaneously

Efficiency (Lv1):
· If 3 mobs fall: 0.375%pt × 3 = 1.125%pt/run
· If SE also falls: 1.125%pt + 0.375%pt = 1.5%pt/run
· One cycle: ~1 minute

■ Story Category

Basic Structure

• Lou and Lavinia depend on the main story
• Jadwiga depends on VIP Pass unlock progress and Zenon
• Josée depends on dedicated quests and Lise
• All others depend solely on dedicated quests

Story Pt by Character

Lou (Main Story — 5 Milestones):

※ More precisely: after the cutscene in MagMell following Hero Zenon's defeat

Iris (4 Dedicated Quests — 7.5 pt each):

Achievable immediately after defeating the three Heroes

"I" in Phalanx likely stands for Iris, "J" for Judy

Noah (4 Dedicated Quests — 7.5 pt each): Requires defeating Frantz first

Must wait until Insula Carcere unlocks.

Josée (5 Dedicated Quests — 6.0 pt each):

The curry you receive is fixed regardless of which spice was used (sloppy design).

Holly (4 Dedicated Quests — 7.5 pt each):

After 2183: The Hero Holly's Era 2 ends, Exploration confirmed at 65.4%. Story is 0%. Past timeline shifts do not contribute to Story pt.

After defeating Camilo, returning to the present (without meeting Monica) and heading to Free Exploration Era causes Holly to appear in MagMell. (Presumed: confirmed once Monica leaves and the Sanatorium event + Lise's hairpin event are done)

Lyle (7 Dedicated Quests — 7.5 pt + 4 pt×5 + 2.5 pt):

After 2182: The Hero Lyle's Era 2 ends, Exploration confirmed at 44.6%. Story is 0%. Exploration pt can accumulate before Affinity display unlocks. Pioneer Castle gets sealed later — collect everything on the first visit.

After defeating Pioneer Queen Imogen (before defeating Lyle), returning to the present and heading to Free Exploration Era causes Lyle to appear in MagMell.

Craig (5 Dedicated Quests — 6.0 pt each):

After 2182: The Hero Lyle's Era 2 ends, Exploration confirmed at 21.1%. Story is 0%. Exploration pt can accumulate before Affinity display unlocks.

After defeating Imogen (before defeating Lyle), returning to the present and heading to Free Exploration Era causes Lyle to appear in MagMell.

Completing all [Requests from Craig] allows him to materialize

Valentin (4 Dedicated Quests — 7 pt×3 + 9 pt): After Free Exploration Era unlocks

23.3333...% = 7 pt. Why not a clean 25% is unknown.

Quest window is tight — requests can only be accepted after each map unlocks.

Lavinia: Gift category only, can increase from the start (after [Talk to Lavinia]).

■ State Immediately After Insula Carcere Unlocks

■ After Hero Zenon Defeated, After Cutscene in MagMell

※ Approximately 60% from item pickups, enemy/boss kills, and drops in Insula Carcere

• On the first visit to Insula Carcere, Partner is locked to Lavinia.
• Story pt is 80% when Insula Carcere unlocks; reaches 100% upon defeating Hero Zenon.
• If you've already unlocked the trophy (e.g., with Iris), feel free to direct all Insula Carcere objects to Lavinia.
• Until Hero Zenon is defeated, Exploration pt can only be gained in Insula Carcere. However, once Zenon's minions (boss) are defeated, Lavinia is removed from the Partner slot — she can be set as Partner again after Hero Zenon is defeated.
• Collecting all objects and defeating regular bosses yields ~23.375%. To hit 100% in the first Insula Carcere visit, ~180 mobs must be killed (including drops, at player Lv1). Killing ~1 mob per pop nets under 100 kills, totaling roughly 60–65%.
• BC/A proficiency only increases for certain enemies. Running 2 laps excluding the boss won't max out A. If you're grinding proficiency, stopping at B is safer.
• [Request from Lavinia] (BC extraction) does NOT raise Affinity.

Jadwiga (Uncanny Stone Collection — VIP Pass Tier: 5 pt×3 + 4 pt×3 + 3 pt): Fastest unlock is picking up Uncanny Stones in MagMell's changing room and handing them over

Depends on [Request from Zenon]

Lise (3 Dedicated Quests — 15 pt + 10 pt + 5 pt): After [Talk to Lise]

All start at 0%. Cannot be set as Partner immediately after unlocking. Can be set after defeating the Predator.

Wandering Specter gives 0.5 pt (1.25%).

Zenon (5 Dedicated Quests — 8 pt + 6 pt×3 + 4 pt): After defeating the 3 Revised Heroes

Exploration is already at 28.4% (accumulated during sub-body kills).

[Tell Jadwiga Zenon's Message] event triggers.

New Game Plus (NG+) Notes

• Exploration and Gifts pt carry over
• Story pt likely carries over but story flags are the trigger (estimated)
• For Lou: even in NG+, must progress until Hero Zenon is defeated (estimated)

■ Affinity Display Unlock Conditions

Noah's display does not unlock in past MagMell immediately after defeating Frantz.

■ Gift Weapons

Unlocked at 72% total (72 pt) — i.e., combined 216% or more

※ After Monica ascends, a golden object appears on Debris Hill

■ Blood Code Unlock

• Guardian's Heart is not held from the start — obtained when heading to rescue Noah; Battle Axe: Idris' Pride also obtained at the same time
• Holly: In Gorge Cave during The Hero Holly's Era, max C proficiency and receive B. Can also get B→S/altS at Sealing Spire
• Lycoris: During escort, be sure to max C and receive B. This is the only opportunity

■ Blood Code Proficiency

• Blood Slave Clara is in Corroded Scar, in the Underground Shelter at the town outskirts — prioritize Lavinia D first.

• If you want Boosters as fast as possible: prioritize Lavinia D Booster first.
• Holly's B: ~45% per lab run. Max with 2 runs + 2 enemies.

• If you don't need Boosters urgently but want efficiency: head straight to Hero Holly's Era and prioritize Lavinia D.
• Don't forget to receive Lycoris B.
