Attack Table
How to Use This Calculator
Customizing Your Build
Select a class, choose your melee weapon and variant, then configure weapon perks, class perks, and teammate perks to match your loadout.
Conditional Modifiers
Toggle conditional modifiers in the sidebar to see how situational bonuses like Parry Bonus, Sanctified Wrath, and perk-specific conditions affect your damage.
Adding Attacks to the Combo Builder
Click the + button on any attack row to add it to your combo sequence. The chart updates in real time showing cumulative damage.
Checking Breakpoints
Select an enemy from the Enemy tab in the Combo Builder to see HP threshold lines on the chart. The line turns green when your combo kills the target, red when it falls short.

For more detail on how damage is calculated, see the Damage Formula and Bonus Types tabs. The Tooltips tab explains the color-coded tooltip system.
Damage Formula
= Base × (Variant + Additive Bonuses) × Motion Value × Strike Type Pool × (Parry + Enemy-Type Bonuses) × Block Charges × Sanctified Wrath × Perk Multipliers × Scan × Enemy Sensitivity
- Base
- The standard damage value of each weapon type; e.g. 11 for Power Axe, 9.5 for Chainsword, 8 for Combat Knife, 14 for Thunder Hammer
- Variant
- Multiplier from the selected weapon variant (Salvation of Bakka Alpha, Ophelian Liberation Gamma, etc.). Higher tiers will have higher multipliers
- Additive Bonuses
- Sum of all +% perk bonuses, which are added to the variant multiplier before multiplication. This includes weapon perks like Perpetual Strength and Armoured Strength, some class perks, and some attack-specific bonuses
- Motion Value
- Per-attack multiplier — each attack (Light 1, Heavy Swing, etc.) has a different value
- Strike Type Pool
- Separate multiplicative layer for bonuses that impact a specific subgroup of attacks, like sprint and ground-pound attacks (e.g. Overcharge, Winged Fury). Only applies to matching attack types
- Parry
- +50% when parry bonus is active. Stacks additively with enemy-type bonuses, not multiplicatively
- Enemy-Type Bonuses
- Sum of all bonuses targeting a specific enemy tier: weapon Slayer perks (e.g. Extremis Slayer +15%), class perks (e.g. Knowledge of the Enemy), and team perks (e.g. Strategic Strikes). Debuffs tied to the target's state rather than its tier land here too (e.g. Shock and Awe +25%)
- Block Charges
- ×1.3 (one charge) or ×1.9 (two charges) based on block charges spent
- Sanctified Wrath
- ×1.35 when active (equipment buff available to any class)
- Perk Multipliers
- Additional multipliers from specific perks like Riposte (×2 on Overhead Strikes out of Power Backstep)
- Scan
- Auspex Scan bonus from ability or Battle Focus parry. Enemies marked by both the Auspex Ability Scan and Battle Focus will take the greater of the two bonuses. All Scan Ability perks (except Battle Focus) are summed prior to multiplying damage
- Enemy Sensitivity
- Damage-type-specific multiplier that determines how much of the player’s damage dealt is absorbed into an enemy’s health pool. Typically ×1, however Trygon Prime and Mutalith Vortex Beast have a ×1.5 melee sensitivity
Damage Bonus Types
Yellow badges on perks indicate how that perk affects damage. The bonus types are explained below.
| +10% |
Additive (+%) — added to the variant multiplier in the (Variant + Additive Bonuses) slot. All +% bonuses from weapon perks (Perpetual Strength, Armoured Strength, etc.) are summed together.
|
| ×20% |
Multiplicative (×%) — applied per enemy tier as (1 + sum of all ×% bonuses). This slot includes Parry Bonus (+50%), weapon Slayer perks, and class perks like Melee Mastery. All ×% bonuses in this slot stack additively with each other and with parry.
|
| ×2 | True Multiplicative (×#) — each one multiplies total damage independently. Examples: Block Charges (×1.3 / ×1.9), Sanctified Wrath (×1.35), and perk-specific bonuses like Riposte (×2). |
| +Attack | Additional Attack (+Attack) — the perk grants an entirely new attack (e.g. Shadow Stab on Combat Knife), adds damage to a previously non-attack mechanic (e.g. Wings of Flame on Assault), or adds an additional instance of damage to an existing attack (e.g. Discharge on Power Axe). In all cases, a new attack row will appear in the attack table. |
Some badges have prefixes:
| C+25% | C = Conditional — same as +% or ×% but only active when a specific condition is met (e.g. after a gunstrike, ability in cooldown, armour remaining) |
| +N% | N = Stacking — variable bonus that builds up (e.g. +3% per consecutive hit, up to 30%) |
| +10% | A gray badge means the perk is not yet wired into this damage calculator. |
Survivability Badges
Some perks make you tougher rather than hit harder. These use coloured badges and drive the Health view (the survivability tab on the side of the attack table).
| +HP | +HP (green) — the perk raises your maximum health pool (e.g. Fortitude, Chapter Banner). The amount is reflected in the Health view's Base HP / Max HP readout. |
| +DR | +DR (blue) — the perk reduces incoming damage (e.g. Steel Within, Hard Target, Iron Rush). Most are conditional or apply to one damage type (ranged or melee); the perk tooltip and the Health view's conditional modifiers show exactly when it applies. |
Ability Badges
Red badges mark perks that affect your class Ability (the ultimate-slot ability: Auspex Scan, Iron Halo, Jump Pack, etc.). These feed the Ability recharge readout shown on the Class page.
| ×20% | Rate change (×N%) — the perk speeds up, or slows down (e.g. ×-33%), your Ability's passive regeneration rate. |
| Refund | Refund — the perk restores a full Ability charge (or 100% of the bar) when its trigger occurs. |
| +15% | Partial restore (+N%) — the perk restores a set percentage of your Ability charge when its trigger occurs. |
Ammo Capacity Badges
Lavender badges mark perks (and the Deep Pockets stratagem) that change how much ammo you carry. When one is active, the affected mag, reserve, or alt rds tile under the weapon picker gets a matching lavender outline. Hover a perk or tile to see the exact impact.
| R+20% | R = Reserve: increases the weapon's reserve (spare) ammo pool by that percentage. |
| M+15% | M = Magazine: increases the loaded magazine (clip) size by that percentage. |
| M+1 | Flat magazine add: adds a fixed number of rounds to the magazine (e.g. Extra Shot, +1 round). |
| M=1 | Magazine cap: sets the magazine to a fixed size (e.g. One Shot caps it at 1 round). |
Magazine and reserve bonuses stack additively. The separate alt-fire (grenade / melta) pool is grown by these perks too: weapon perks add to it, while class and Deep Pockets buffs multiply it. All ammo values are rounded up.
Tooltips
Hover over any perk with a yellow badge to see gold italic text in the tooltip explaining how that specific bonus stacks.
Tooltip Info Colors
- Gold italic
- Mechanic explanation — how a specific bonus stacks or is applied
- Green text
- Perk impact estimate — hover over any available (unselected) perk to see the estimated damage change. If the attack table is filtered by Attack or Type, the impact is calculated using only the visible rows.
- Red text
- In-game behavior differs from the perk's description
