Damage

Inflicting Damage

A character's base damage is the main factor all other damage scales off of.

An accumulator is built with base value of 1.0, to which any of the following contributions are added together:

1. +0.1 for each instance of BoostDamage the character has.
2. +(x * teamSize - 1), where x is the number of Empathy CoresEmpathy Cores

7. -0.3 if the character holds the Elite Void equipment (only granted to Void Infested enemies).

This multiplier is applied to the character's base damage plus their level's damage, resulting in the character's damage. After this, the following reduction and increases are applied in order:

1. If the character is an invading doppelganger, multiply their damage by 0.04.
2. If the Artifact of Glass is enabled and the character is on the player team, multiply their damage by 5.
3. If the character is weakenedNatural Toxins (Passive)Certain attacks Weaken enemies hit, reducing their movement speed, armor, and damage.

   When the Tonic wears off, you have a 20% chance to gain a Tonic Affliction, reducing all of your stats by -5% (-5% per stack). is active, multiply their damage by 2.
5. Otherwise, if the Tonic is not active and the character has at least 1 Tonic Affliction, multiply their damage by 0.95^x, where x is the amount of Tonic Afflictions held.

Hit Damage

Each hit has damage info. This is scaled (possibly indirectly) from the character's damage. It holds the following properties: the attacker, the damage, if it is a critical strike, the damage type, the proc coefficient, the proc chain, position and force for knockback-related calculations, the damage color and if the damage was rejected for displaying the damage. Upon hitting a character, the following things are done in order:

1. The character applies the damage to themselves. (see: Receiving Damage)
2. The game checks if on-hit items need to trigger and DoTs need to be applied. (see: Handling Hits)
3. The game checks if the attack needs to explode. (see: Handling Hits)

Note that bullet attacks will always execute the 3rd step whether they hit a character or terrain in their path, while steps 1 and 2 require the hit to be on a character. Note that since Artificer'sArtificerThe Artificer is a high burst damage survivor who excels in fighting large groups and bosses alike.

Explosive projectiles will also trigger the 3rd step upon making contact with anything.

Damage Falloff

Damage falloff is a statistic that determines whether an attack will hit at full or reduced damage. Attacks that have damage falloff discourage shooting from extreme ranges and reward accuracy with area of effect attacks. There are two falloff models: a bullet falloff model and an area of effect (AoE) falloff model.

• Bullet falloff is used for hitscan bullet attacks, such as Double TapDouble Tap (Primary)Rapidly shoot an enemy for 100% damage.
  Survivor: Commando, BurstBurst (Primary)Fire a shotgun burst for 5x100% damage. Can hold up to 4 shells.
  Survivor: Bandit, and Vulcan ShotgunVulcan Shotgun (Primary)Fire a blast of pellets that deal 8x120% damage. Charging the attack narrows the spread.
  Survivor: Captain. Attacks that launch an actual projectile, such as Cast Nano-SpearCast Nano-Spear (Secondary)Freezing. Charge up a piercing nano-spear that deals 400%-1200% damage.
  Survivor: Artificer, do not use this falloff model. If an attack has bullet falloff, its final damage is determined by the distance between the attacker and the target, with three types:
  • None: Deals 100% damage, regardless of distance. For example, BlastBlast (Primary)Fire a rifle blast for 330% damage. Can hold up to 4 bullets.
    Survivor: Bandit is a skill that uses this type.
  • Default: Deals 100% damage within 25m, linearly decreasing to a minimum of 50% at 60m or farther. Most hitscan attacks will use this type.
  • Buckshot: Deals 100% within 7m, linearly decreasing to a minimum of 25% at 25m or farther. For example, Phase BlastPhase Blast (Secondary)Fire two close-range blasts that deal 8x200% damage total.
    Survivor: Commando is a skill that uses this type.

• AoE falloff is used for exploding attacks, such as Frag GrenadeFrag Grenade (Special)Throw a grenade that explodes for 700% damage. Can hold up to 2.
  Survivor: Commando, Charged Nano-BombCharged Nano-Bomb (Secondary)Stunning. Charge up a exploding nano-bomb that deals 400%-2000% damage.
  Survivor: Artificer, and OGM-72 'DIABLO' StrikeOGM-72 'DIABLO' Strike (Utility)Stunning. Request a kinetic strike from the UES Safe Travels. After 20 seconds, it deals 40,000% damage to ALL characters.
  Survivor: Captain. If an attack has area of effect falloff, its final damage is determined by the distance from the explosion's center to the target, with three types:
  • None: Deals 100% damage, regardless of position inside the explosion. For example, the Brilliant BehemothBrilliant Behemoth
    All your attacks explode!
    All your attacks explode in a 4m (+2.5m per stack) radius for a bonus 60% TOTAL damage to nearby enemies. uses this type.
  • Linear: Deals 100% damage at the explosion's center, linearly decreasing to 0% at the explosion's edge. For example, the Clay Dunestrider'sClay Dunestrider
    Ravenous SymbiontHP: 2100 (+630 per level)
    Damage: 25 (+5 per level)
    Class: Ranged
    Speed: 9 m/s
    Armor: 20 Rolling Tarballs uses this type.
  • Sweet spot: Deals 100% from the explosion's center to half of its radius, and deals 25% from half its radius to its edge. Most exploding attacks will use this type.

'Base' vs. 'Total' Damage

Base damage and total damage are the two main damage types in Risk of Rain 2.

• Base damage scales specifically with the character's base damage value. For instance, take CommandoCommandoThe Commando is a jack-of-all-trades character that is reliable in all situations of the game.
  Class: Ranged
  HP: 110 (+33 per level)
  Damage: 12 (+2.4 per level)
  Armor: 0
  Umbra: Cornered Gunslinger at level 1, with a base damage stat of 12, and assume he has inflicted a single stack of BleedBleed (Debuff)
  Damage over time.Deals 240% damage over time [3 x proc coefficient] (20% per tick, 4 ticks per second).
  (stackable) thanks to his Tri-Tip DaggerTri-Tip Dagger
  Gain +10% chance to bleed enemies on hit.
  10% (+10% per stack) chance to bleed an enemy for 240% base damage.. The damage from bleeding deals 20% base damage per tick, so it will deal 20% x 12 = 2.4 points of damage per tick. This tick damage is not affected by the attack that inflicts the bleeding; it only will deal more damage as Commando levels up and his base damage increases.
• Total damage is used for on-hit items that generate bonus attacks. These items scale with the strength of the attack that activates them. For instance, take another level 1 Commando (still with a base damage of 12), and assume he has shot an enemy one time with Phase RoundPhase Round (Secondary)Fire a piercing bullet for 300% damage. Deals 40% more damage every time it passes through an enemy.
  Survivor: Commando, inflicting 300% x 12 = 36 damage. If Commando has one AtG Missile Mk. 1AtG Missile Mk. 1
  Chance to fire a missile.
  10% chance to fire a missile that deals 300% (+300% per stack) TOTAL damage. and his Phase Round activates it, the missile deals 300% of the Phase Round shot, for 300% x 36 = 108 damage. If this missile in turn activates a Sticky BombSticky Bomb
  Chance on hit to attach a bomb to enemies.
  5% (+5% per stack) chance on hit to attach a bomb to an enemy, detonating for 180% TOTAL damage., the Sticky Bomb will deal 180% of the missile's damage, dealing 180% x 108 = 194.4 damage.

Multiple different total damage items may activate at once from a single hit, or they can activate each other, leading to cascading item activations (commonly referred to as a "proc chain"). There are several important quirks to keep in mind with regard to proc chains:

• Total damage items calculate their final damage without accounting for any damage bonuses on the triggering hit, in order to prevent those bonuses from being repeatedly applied as the chain grows longer; instead, the bonuses are calculated on a per-hit basis. The items that are impacted by this are the Focus CrystalFocus Crystal
  Deal bonus damage to nearby enemies.
  Increase damage to enemies within 13m by 20% (+20% per stack)., CrowbarCrowbar
  Deal bonus damage to enemies above 90% health.

  Click for more info.Delicate Watch
  Deal bonus damage. Breaks at low health.
  Increase damage by 20% (+20% per stack). Taking damage to below 25% health breaks this item.. For instance, an attack that deals 100 damage that is boosted by 1 stack of Armor-Piercing Rounds bonus will deal 120 final damage. If this attack activates an AtG Missile Mk. 1, that missile will only deal 300% x 100 = 300 damage; the extra damage from the Armor-Piercing Rounds is not taken into account when calculating its initial damage. However, if that missile strikes a boss, then it will also be boosted and deal 360 final damage.
• Total damage items only critically strike if the triggering hit was a critical strike, and can never critically strike otherwise. For example, if a non-critical attack deals 100 damage and activates an AtG Missile Mk. 1, the missile will deal 300% x 100 = 300 damage and is sure to not be a critical strike. If we instead assume the original attack is a critical strike, the missile will become a critical strike as well, dealing 2 x 300% x 100 = 600 final damage (note that the critical strike bonus also applies to each attack individually, similar to the above bonuses). The lone exception to this is the Charged PerforatorCharged Perforator
  Chance on hit to call down a lightning strike.
  10% chance on hit to down a lightning strike, dealing 500% (+500% per stack) damage., which rolls critical strike chance completely independently of the triggering hit (this may be a bug).
• A given total damage item can only activate once per proc chain. For instance, if the player activates an AtG Missile Mk. 1, that missile (and any other total damage items activated by it) will not activate the AtG Missile Mk. 1 again in that same chain. This is sometimes referred to as a "proc mask," preventing proc chains from escalating for extremely long times.

Damage over Time

Damage over time refers to negative status effects that cause the victim to continuously take damage until the status expires. These status effects each deal damage a certain number of times per second, and they each have a set base duration (which may be multiplied by the proc coefficient of the attack that inflicts the debuff).

Additionally, some of these debuffs can stack, dealing proportionally more damage per tick with more stacks. BleedBleed (Debuff)
Damage over time.Deals 240% damage over time [3 x proc coefficient] (20% per tick, 4 ticks per second).
(stackable) and HemorrhageHemorrhage (Debuff)
Damage over time.2000% base damage over 15s.
(stackable) are unique in that when a new stack is applied to a target, all the existing stacks of that debuff that have a lower duration remaining are "refreshed," with their durations becoming equal to the newest stack. This means that these debuffs can be infinitely stacked as long as they are continually reapplied.

IgniteBurn (Debuff)
Damage over time, disable health regeneration.Applies a percent of damage over time, and disables health regeneration.
(stackable) is a special case among damage over time debuffs, in that it does not have a definite duration; instead, its duration is proportional to the strength of the inflicting hit. For example, an attack that deals 1000% base damage will inflict Ignite for 10 seconds, but an attack dealing 100% base damage will inflict it for only 1 second. Each tick deals a constant 10% base damage (with 5 ticks per second), and Ignite's duration scales such that it always deals 50% total damage over its entire duration (for instance, a stack of Ignite inflicted by the above 1000% base damage attack would deal an additional 500% base damage over its duration).

Knockback

Knockback is applied to a character upon receiving damage, pushing them away some amount. How much a victim is knocked back depends on 2 factors: the force of the attack and the victim's mass.

• Force is a vector applied by an attack to the victim that pushes them in a direction. For instance, a bullet will apply a force in the same direction, while an explosion will apply a force away from its center.
• Mass is a statistic inherent to a given character. A character with greater mass suffers less knockback.

The final knockback applied to the victim is the quotient of the attack's force vector and the victim's mass. An attack with greater force will inflict proportionally more knockback (for instance, OGM-72 'DIABLO' StrikeOGM-72 'DIABLO' Strike (Utility)Stunning. Request a kinetic strike from the UES Safe Travels. After 20 seconds, it deals 40,000% damage to ALL characters.
Survivor: Captain inflicts greater knockback than Double TapDouble Tap (Primary)Rapidly shoot an enemy for 100% damage.
Survivor: Commando). Likewise, a victim with greater mass will receive proportionally less knockback (for instance, AcridAcridAcrid is a melee-range hybrid who uses powerful poisons to melt tanky enemies.
Class: Melee / Ranged
HP: 160 (+48 per level)
Damage: 15 (+3 per level)
Armor: 20
Umbra: Test Subject only suffers half as much knockback as LoaderLoaderThe Loader is a slow but powerful bruiser that can use her grappling hook to uniquely navigate the environment.
Class: Melee
HP: 160 (+48 per level)
Damage: 12 (+2.4 per level)
Armor: 20
Umbra: Bionic Powerhouse, since Acrid has 300 mass compared to Loader's 150).

Additionally, if after knockback calculation the y-axis component of the knockback vector is less than 6, and the victim is standing on the ground, the y-axis component becomes 0 instead, so the victim is only pushed horizontally.

Receiving Damage

This procedure is used for players and enemies alike.

The game begins by creating a copy of the incoming damage amount. We'll call this new copy 'amount', whereas we'll call the old damage 'original amount'.

One-Shot Protection

(See also: Health)

One-shot protection is visible on the HUD as a faint overlay on the health bar, protecting the player from dying to a single instance of damage when above 90% health. "Curse" effects which lower maximum health by 10% or more, such as Shaped GlassShaped Glass
Double your damage... BUT halve your health.
Increase base damage by 100% (+100% per stack). Reduce maximum health by 50% (+50% per stack). or the Artifact of Glass, will remove one-shot protection.

A single hit taken cannot deal more than (health + shield + barrier) × 0.9 damage. This is checked after damage-reducing effects such as armor are applied.

After receiving damage that triggers one-shot protection, the protection will remain for 0.1s, meaning health cannot be reduced below the resulting health after the initial hit.

Version History

Anniversary Update

• Quality of Life
  • Graphics Updates
    • Update damage numbers to be more legible

---

Early Access Content Update 5

• Gameplay Changes
  • Slightly reworked OSP. The goal is to fix inconsistencies and make it actually protect you from one-shots - while also fixing some abuse cases with curse.
    • The threshold for OSP is now displayed on the healthbar with a faint graphic.
    • Now has a lingering 0.1s duration when activated.
    • 🌧 Now is subtracted via Curse ( Shaped GlassShaped Glass
      Double your damage... BUT halve your health.
      Increase base damage by 100% (+100% per stack). Reduce maximum health by 50% (+50% per stack)., Artifact of Glass, etc), i.e a curse of 10% will remove OSP entirely.
    • 🌧 Update OSP logic so it still triggers if you receive multiple sources of damage in the same frame that go past OSP values, i.e MalachiteMalachite (Affix Buff)
      Gain the power of a Malachite Elite.Shoot occassional urchins and apply healing disabled on hit. Lesser WispsLesser Wisp
      HP: 35 (+10 per level)
      Damage: 3.5 (+0.7 per level)
      Class: Ranged
      Speed: 6 m/s
      Armor: 0
  • Melee Survivors
    • 🌧 Melee skills will now perform more consistently at high attack speeds.
    • Melee skills will now scale hitpause duration with attack speed - since the pause when hitting enemies were static, melee characters actually scaled poorly with attack speed.
    • Melee skills will now ‘hold’ you in the air better at high attack speeds.

Early Access Artifacts Content Update

• Gameplay Changes
  • 🌧 Update how AOE falloff is calculated to be more accurate
    • Developer Notes: This affects AOE attacks that did less damage at the edges, like Commando’s Grenade and MUL-T’s Scrap Launcher. They should now do full damage with a direct impact - however, this also affects enemies as well!
  • Characters with damage interrupt thresholds like Lesser WispLesser Wisp
    HP: 35 (+10 per level)
    Damage: 3.5 (+0.7 per level)
    Class: Ranged
    Speed: 6 m/s
    Armor: 0 and LemurianLemurian
    HP: 80 (+24 per level)
    Damage: 12 (+2.4 per level)
    Class: Ranged / Melee
    Speed: 7 m/s
    Armor: 0 now use total damage received instead of incoming damage with a crit modifier when determining whether or not they should be interrupted when hit. This makes these interrupts more likely when using items that modify damage like CrowbarCrowbar
    Deal bonus damage to enemies above 90% health.
    Deal +75% (+75% per stack) damage to enemies above 90% health. and Focus CrystalFocus Crystal
    Deal bonus damage to nearby enemies.
    Increase damage to enemies within 13m by 20% (+20% per stack)..
• Bug Fixes
  • 🌧 Fix issue which caused blast attacks to calculate hit distance based on the center of the hit hurtbox instead of the closest point. The overall effect of this is that blast attacks with falloff will do more damage since objects will now be considered closer than they were, especially against monsters with large hurtboxes like the Stone TitanStone Titan
    Crisis VanguardHP: 2100 (+630 per level)
    Damage: 40 (+8 per level)
    Class: Ranged / Melee
    Speed: 5 m/s
    Armor: 20.

Early Access Hidden Realms Content Update

• Gameplay Changes
  • Change ‘One Shot Protection’ calculation to include barrier
    • Our intent in changing OSP in this manner is to make sure that it is a hidden mechanic, not a reliable one to build a strategy around. We know there’s still edge cases that are abusable - but as long as it’s not ALWAYS the best strategy, we don’t mind having some end-game builds that are extremely powerful.
    • If you have 100% Health and 100% Barrier and take a billion damage, previously you would remain at 100% Health and 10% Barrier. You will now be at 10% Health, as intended before the inclusion of barrier in Scorched Acres.
• Quality of Life
  • 🌧Update right edge of execution threshold bar not lining up with the actual value

---

Early Access 'Skills 2.0' Content Update

• QOL
  • 🌧︎ Damage numbers can now support up to 998,000,000 damage (truncated as 10K, 100K, 1M, etc)

---

Early Access Scorched Acres Content Update

• Gameplay Changes
  • ☂ Critical Strikes no longer double/triple/quadruple/etc “dip” through the proc chain
    • On-hit items have accidentally been benefiting multiple times from critical strikes, resulting in each proc doubling in damage for huge multipliers. While neat, this was ultimately unintentional and not sustainable for the game going forward - so we’re ripping the bandaid now and fixing it. On-hit items have been compensated for the removal of power from this fix.
• QOL
  • Change damage with no team assigned to be Grey
• Bug Fixes
  • ☂ Fix ‘Enable Damage Numbers’ not saving between playthroughs

---

Early Access Patch (Build ID No.3830295)

• Bug Fixes
  • Reorganize fall damage code to try to fix issues with the server reporting false fall damage hits

---

Early Access Patch (Build ID No.3743353)

• Bug Fixes
  • Fixed an issue where enemies executed from freezing didn't call the correct events, leading to no money, on-kill procs, and potentially a stalled Teleporter event.

Trivia

• If Damage Numbers are enabled in Gameplay Settings, the damage will be displayed after rounding up to the nearest integer, for a maximum of 990,000,000, abbreviated as 990M.
