SM2 Melee Damage 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.

Unlocking the Build

Adding attacks to a combo locks your build configuration. To make changes, click the Clear Attacks & Unlock Build button inside the combo, or remove individual attacks using the × buttons. You can also click the Unlock Customizations button in the sidebar to unlock without clearing your combo.

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.

+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.

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.
