Overview

Welcome!

This is an assorted notebook of Loveless information, testing, mechanics and builds from the Soup Kitchen Discord Server.

The guide is quick info style, and not an in-depth damage formula exploration guide. It includes all of our notes regarding Loveless testing.

You may find useful information for your own buildcrafting and understanding here.

Confused by terminology and formulas? Check out the Damage Formula Guides.

Skills & Passives

Hack / Slash Skills & Passives

Tier 1

Disdain

  • Crit damage goes into Crit Skills category of the damage formula.

Tier 2

Odium

  • Goes into Gear Crit category of the damage formula. The description also lies, with the actual formula being:

(Skill Tree Crit Damage from Disdain) x [ ( (OdiumPointsAmount) x 1.5) + 2 ]

Tier 4

Methodical

  • The Gun Damage is On Hit Gun Damage (Soup).

The formula for Methodical is:

(“Up to” Gun Damage Skill Card Value) / (Weapon Card Fire Rate x Fire Rate Boosts)

  • This formula is affected by ANY Fire Rate boosts and mode switches.
    • The Stop Gap Fire Rate Special Effect does not boost it.
  • ‘Up to’ value is achieved at exactly 1.0 Fire Rate, but it can continue scaling further at lower values.

The Sweet Science

  • Is a Double Dip. 
  • Causes a Random Element DOT that deals 100% of the Damage Dealt as a tick, for 16 ticks.
  • If it rolls Contagion, it’s not a double dip, and Contagion deals its terrible normal base damage.
  • If it rolls Cryo, it instantly freezes the enemy and deals appropriate damage per tick. If the enemy is immune to getting frozen, it doesn't cause damage over time.

Tier 5

Siliconventional Warfare

  • The Gun Damage is On Hit Gun Damage (Soup).

Retribution

  • Crit damage goes into Crit Skills category of the damage formula.

Tier 6

Refactored Damage Formula

  • Is a Pure Multiplier.
  • 220% at 2/1.

Manifestation Skills & Passives

Symbiosis

  • Symbiosis stacks are all lost when Malignant Construct ends.
  • When Wyrm dies, Malignant Construct ends, unless you have UUDDLRLRBAS.
  • Symbiosis stacks cap at 25, and each lasts 4 seconds.

Tier 1

Drift Compatible

  • Crit damage goes into Crit Skills category of the damage formula.

Corrupted Path

  • 4% Bonus Radiation damage per Symbiosis stack at 1/5. The Bonus Damage does not scale with further investment.
  • The non-Bonus, passive Radiation Damage boost that scales with points is Soup.

Tier 2

Finisher

  • The Gun Damage is On Hit Gun Damage (Soup).
  • 150% at 5/5 and 10 stacks.

Tier 4

Storage Upgrade

  • Applies the % boost to Empowered Melee as 42.5% Soup (5/5).
    • This also applies to Source Adopting Bonus Elements on Empowered Melee.
  • Applies to the On Shot Gun Damage Bonus from RAM: 42.75% at full, up from 30%.

Status Update

  • The Element of the Bonus Damage will be based on the first element you apply a DOT with.
  • Different elements don't stack. Only one instance of the skill may be active at once.
  • Duration cannot be refreshed.
  • % Doubles if triggered by a Radiation Status.
  • Contagion and Cryo grant nothing.
  • BUG: Corrosive Status grants Kinetic Bonus Damage, not Corrosive.

Tier 5

Power Overwhelming

  • The Element of the Bonus Damage will be based on held gun's Element.
  • Different elements don't stack. Only one instance of the skill may be active at once.
  • % Doubles if triggered while holding a Radiation Element gun.

IHATEYOU

  • Is considered Wyrm Damage, meaning it can benefit from Devourer.
  • Can be triggered from both Wyrm and Loveless kills, as long as they happen through non-Status Radiation Damage.

Feedback

  • Seems to be 11%, not 15%.

Tier 6

Intrusion

  • Global 100% Crit chance. Does work on Wyrm.
  • Actually landing the Empowered Melee attack is required for it to trigger.
  • Duration is not refreshable.

Host Privileges

  • Action Skill Damage Soup for Functions and Executables.

UUDDLRLRBAS

  • When it procs, it sets Action Skill Duration left to 12s, even if you have less than 12s left.
  • From that point, Duration can still be restored even if you fail to respawn Wyrm by hitting the Orb. The main benefit from that is you don't lose Symbiosis Stacks when the Action Skill Timer runs out.
  • When you respawn Wyrm by shooting the Orb, your Action Skill duration gets restored to full.

Second Impact

  • Is not considered Wyrm damage.
  • No internal cooldown.
  • Doesn't seem able to trigger itself.

Virology Skills & Passives

Tier 1

High Data Rate

  • Consuming Empowered Melee guarantees a DOT on the next Elemental Attack.

UNLISTED FEATURE 1:

  • DOT damage is equal to 300% of Damage Dealt per second.
  • It's a Double Dip.
  • The DOT lasts 12.5s.
  • Can create Cryo DoTs.
  • Any non-Status Elemental Instance will consume the Auto-DOT.
    • ‘Fake’ statuses like Contagion can consume it.
    • Empowered Melee and any attached Bonus Elements to it cannot consume it.
    • Bonus Elements on Groundbreaker can consume it.

UNLISTED FEATURE 2:

  • Killing enemies with a Radiation DOT from High Data Rate grants Loveless a Radiation 'Aura' around her, based on that damage (?).
  • This 'Aura' can instantly light up and blow barrels and other environmental hazards, which can and will kill you. It can also instapop enemies if you feed it enough damage.
  • Yes, it is utter nonsense and we don't know why it exists.

Only needs 1 point of investment to achieve all of the above. Further investment only grants increased Status Effect Chance (listed on Skill Card), which you might have forgotten even is a part of the skill at this point. You're welcome for the reminder!

Tier 2

Central Procing Unit

  • Applies a Random Status Effect equivalent to the Main Status Effect in both Duration and Damage.
  • Can apply Contagion, in which case it will use Contagion’s base values and not the source DOT’s.
  • You can still apply a bonus DOT to an enemy that already has a DOT in the same element as the one you applied.
    • Example: Corrosive DOT applied to enemy, you can still get bonus DOT on a 2nd corrosive DOT you apply. 
  • Gets Status Soup.
  • 10/5 is a guaranteed proc chance on Status Effect application.
  • Chance based per pellet. Has a hard cap of 5 elements applied max. tou have 6 status effects now with Contagion, so 1 of 6 elements will not proc.
  • Contagion sprites that seek out enemies will proc their own Central Procing Unit. This will continually chain if the enemy is killed since Contagion Sprites always apply Contagion. Sadly is based off of DOT applied which means Contagion CPU DOT will always be low.
    • CPU Contagion DOTs benefit from Host Compromise, meaning it will send 6 sprites out instead of 3 without having to activate Plague Star.
  • Mixologist Maliwan Enhancement can apply its own instance.
  • Transfuser Maliwan Enhancement can apply its own instance.

Tier 5

Malware

  • Skill & Ordnance Damage. 
  • Only benefits from Skill Tree Splash Radius, and not other Radius bonuses.

Action Skills, Functions & Executables

Visual Paradox Nexus

Visual Paradox Nexus

VPN is an aggressively bugged Action Skill, having a bunch of unlisted effects and features related to augments and gear.

  • Grants 25% Skill Tree Crit Damage while VPN is Active. This is a listed effect.
  • UNLISTED: Grants 50% All Damage Soup while in Stealth. This is likely a Montage Maker-related bug.
  • UNLISTED: The first shot upon entering Stealth will have +150% Gear Crit.
    • Subsequent shots (after the first) in or out of Stealth will only have the 25% Skill Tree Crit instead.
  • UNLISTED: Upon entering Stealth, you gain 150% Skill Tree Crit Damage. This is lost instantly upon pulling the trigger.
    • This means the 150% Skill Tree Crit Damage is generally unusable with actual gunshots, but can be used through gun Ricochets and non-gunshot effects.
    • We suspect this is related to sudo kill bugs.
  • UNLISTED: VPN has yet ANOTHER unlisted property. sudo kill has broken code that makes its Overkill Damage feature be active during VPN no matter which augments you select. This allows for absurd damage escalation on certain builds.

First Stealthed Shot Crit Formula

  • [ (Base x OnShot x Amp) x [1 + 0.5 + Soup + (1 + GearCrit + 1.5 + (2 x 0.25)] ]

Subsequent Stealthed Shot Crit Formula

  • [ (Base x OnShot x Amp) x [1 + 0.5 + Soup + (1 + GearCrit + (2 x 0.25)] ]

Unstealthed Shot Crit Formula

  • [ (Base x OnShot x Amp) x [1 + Soup + (1 + GearCrit + (2 x 0.25)] ]

Base Function: Kusarigama

  • Is Action Skill; Is Melee Damage. Can build up Groundbreaker.
  • Is not Player Melee Attack, meaning it doesn’t deliver Groundbreaker.

Augment: Stack Overflow

  • Is a Double Dip.
  • Is Action Skill Damage.
  • Is Melee Damage.
  • Can build up Groundbreaker.
  • Does not get consumed if the Function/Executable misses or doesn’t hit any enemy.
  • Damage to store is checked ON HIT, meaning it is relatively anti-synergistic with multiple pellets and source-adopting Bonus Elements like Watts 4 Dinner.
    • This doesn't mean you should never use Watts 4 Dinner or multipellet weapons. It ends up a mostly irrelevant factor, because...
  • On each re-stealth, you get an additional 3 shots (instances) that will stack stored damage for Stack Overflow. This DOES NOT overwrite already stored damage, which means the longer you go without using the Function, the more damage Stack Overflow will end up doing whenever you use it.
    • This may be a bug/unintended. We sincerely have no idea.
  • UI Icon is super buggy and can just disappear even though you’re still storing the damage, or have it fully stored.

Stack Overflow Formula: 

  • [(Base + StoredDamage) x (1 + ActionSkill + Melee + Soup + Crit)]

Augment: sudo kill

  • The Overkill part of this augment is bugged and currently permanently active even without having sudo kill equipped.
  • VPN no longer provides 50% All Damage Soup during Stealth. 
    • This might be because it makes Stealth end on shooting/etc. And the fact this is probably a Montage Maker-related bug in the first place.

sudo kill Overkill Shot Formula:

  • [ [(Base x OnShot x Amp) + StoredOverkillDmg] x (1 + Soup + Crit)] ]
  • Does not split per pellet.
  • Applies to Ricochet damage.
  • Overkill stacks seemingly an unlimited amount.
  • Can only get a maximum of +5001 Overkill per kill.

sudo kill Overkill Reset Condition:

  • If killing shot’s Overkill Damage < Stored Overkill Damage, resets StoredOverkillDmg
    • StoredOverkillDmg is not lost if a shot misses or is not a Killing Shot. It will only check for the above on actual Killing Shots.
    • StoredOverkillDmg is lost if VPN ends.

Executable: accelerat.exe

  • 250% Amp (x3.5). Additive to Shield and Repkit Amps.

Malignant Construct

Malignant Construct

Function: Intelligent Artifice

  • Seems to apply to all Wyrm damage, including IHATEYOU Shurikens and DOTs.

Executable: Base Breath Attack

  • Deals Melee Radiation Damage about 3 times per second for 6 seconds. 18 or 19 total procs.
  • Hitbox seems to depend on Wyrm’s elevation at the start of the attack. Can whiff.

Executable: barrag.exe

  • Increases the hitbox of the breath attack substantially, misses far less often compared to base.

Executable: enrag.exe

  • Changes Melee Animations from Tail Swipe to Head Swipe. Larger horizontal hitbox. Also adds a new Melee Attack with 2 quick swipes. 
  • Equipping this Executable doubles all melee damage Wyrm deals, including the Melee Damage on the card of this Executable.

Plague Star

Plague Star

Capstone: fulminat.exe

  • Enemies explode again after 2s
  • Stacks
  • Works with:
    • Base Executable
    • Burst Finish Augment

Bonus Elements

Hack / Slash Bonus Elements

Biathlon

The Bonus Radiation Melee Damage:

  • Is not Source-Inheriting.
  • Is Skill Damage and Melee Damage.
  • Can only crit through Crit Chance.
  • Is not considered a Melee Attack, therefore cannot deliver Groundbreaker.
    • It cannot build Groundbreaker either, due to not Source-Inheriting and being just Skill + Melee Damage.
  • Can trigger 'Melee Damage Required' effects such as CQC, Flurry and Upload.

Siliconventional Warfare

The Bonus Corrosive Melee Damage:

  • Is not Source-Inheriting.
  • Is Skill Damage and Melee Damage.
  • Can only crit through Crit Chance.
  • Is not considered a Melee Attack, therefore cannot deliver Groundbreaker.
    • It cannot build Groundbreaker either, due to not Source-Inheriting and being just Skill + Melee Damage.
  • Can trigger 'Melee Damage Required' effects such as CQC, Flurry and Upload.

Manifestation Bonus Elements

Corrupted Path

The Bonus Radiation Damage:

  • Is Source-Inheriting.
  • Is Global, behaving like Protean Cell Bonus Shock. This means it even applies to Status Effects.
  • Is not Skill Damage, unless applied to a Skill Damage source.

Power Overwhelming

The Bonus Elemental Damage:

  • Is not Source-Inheriting.
  • Is not Skill Damage.

Status Update

The Bonus Elemental Damage:

  • Is not Source-Inheriting.
  • Is Skill Damage.

Virology Bonus Elements

Toxic Chat

The Bonus Corrosive Damage:

  • Is not Source-Inheriting.
  • Is Skill Damage.

Depletion Load

The Bonus Radiation Damage:

  • Is not Source-Inheriting.
  • Is Skill Damage.

Viral Payload

The Bonus Corrosive Damage:

  • Is not Source-Inheriting.
  • Is Skill Damage.

Class Mods

Devourer Devourer

  • Chance is flat, added per Symbiosis stack.
  • Damage is based on target's Current HP, not their Total HP.
    • It works like a post-add damage for Wyrm attacks, so it can get all relevant Soup.
  • Works on IHATEYOU Shurikens, since those are considered Wyrm Damage.

Memory Hoarder Hoarder

  • Description lies. Aggressively. It doesn't grant Increased Ram Bonuses.
  • Instead, it grants On Shot Gun Damage per stack, using the following formula:

While at least 1 Stack is Active, gain: '30% + (100% x Stack Count)' On Shot Gun Damage.

  • No Bonuses are provided at 0 stacks other than RAM default bonuses.
  • Stacks are refreshable.

Miscellaneous

RAM

  • The Gun Damage is On Shot Gun Damage.
    • This means it is additive to Enhancement Gun Damage boosts, and affects the damage caused by Gun Status Effects.

Contagion

  • Is Action Skill Damage and Status Damage.
    • Gains access to Ordnance Damage when using Boomer.
  • Can crit through Skill Crit Chance.
    • Gains access to Ordnance Crit Chance when using Boomer.
  • Detonations only care about 1 stack. Having 20 stacks does not buff Detonation Damage.
  • Can consume High Data Rate due to being a ‘fake’ Status.

Footwork

  • Maximum of 100 Stacks.
  • Movement Speed does not stack between multiple Footwork skills.

Empowered Melee

  • Can deliver Groundbreaker.

Bug Report

Hack / Slash Bugs

Visual Paradox Nexus

  • Whatever in the cursed hell is going on with this Action Skill. It has intrinsic bugs related to sudo kill without sudo kill even being equipped.

Killing Machine

  • Doesn’t seem to work with Wyrm Malignant Construct at all.

Manifestation Bugs

Storage Upgrade

  • Doesn't grant more than 1 Symbiosis Stacks on Empowered Melee when used with Puppetmaster + Visual Paradox Nexus.

Fusion Friends-y

  • Doesn't grant more than 1 Symbiosis Stacks on Kill when used with Puppetmaster + Visual Paradox Nexus.

Status Update

  • Corrosive Status grants Kinetic Bonus Damage, not Corrosive.

Virology Bugs

Plague Star

  • Shurikens will randomly not do damage or clip through environment. This includes Base Shurikens and replicat.exe.
  • Contaminant Damage increases by a flat amount that Contagion stacks receive.

Kernel Panic

  • The damage portion doesn't seem to work at all.

fulminat.exe

  • Doesn't work with:
    • Contaminants
    • Malware

Class Mod Bugs

Montage Maker

  • VPN Stealth bugs out when you leave stealth using Function: Kusarigama while wearing this class mod. Kills stop re-stealthing and you’re forced to wait the 8s from the class mod instead.
  • It's possiblt this happens through other mean too, but it needs checking.

Puppetmaster

  • Refer to the Storage Upgrade and Fusion Friends-y bugs.
