Frost Blades is a cold melee attack skill that strikes with increased range, then has the secondary effect of releasing projectiles behind the struck enemies.

Skill functions and interactions

  • Dual Wielding: Since Frost Blades has no weapon restrictions, attacks will alternate between both hands while dual wielding.

An attack with Frost Blades consists of two parts:

When an enemy is hit by this skill, multiple homing projectiles fly out from behind the enemy and target nearby enemies. This skill increases the melee range by an appreciable degree. Unlike Lightning Strike, if the initial attack does not hit an enemy, then no projectiles are released.

The projectiles have the same damage multiplier as the initial melee hit, with the same cold damage conversion. However the initial melee attack scales with melee damage modifiers (such as Melee Physical Damage), whereas the projectiles scale with projectile damage modifiers. Both components scale equally with (unspecified) attack, physical, and cold damage modifiers.

Multistrike uses the increased attack range of this skill when selecting targets to attack. Melee Splash does not release additional projectiles from secondary targets struck by the initial melee splash, nor does it splash the projectiles' damage. Faster Projectiles will increase the speed and effective range of the secondary projectiles. Vicious Projectiles scales all the damage of the projectiles, but not the initial melee attack: attack speed is NOT reduced since the attack animation itself is melee, rather than projectile.

Note: the tooltip DPS shows only the melee attack component damage and DPS. It does not show damage values for the projectile component. To calculate the projectile component, use the formula at the bottom of this page.

Projectile Damage Calculation

To calculate the projectile damage (or DPS) given the melee tooltip damage (or DPS) use the following formula:


  • IAD = Sum of all % increased attack damage (not including either melee or projectile specific increased damage nor effects from Strength)
  • IMD = Sum of all % increased melee damage (including effects from Strength)
  • IPD = Sum of all % increased projectile damage (including effects from Strength if Iron Grip is applicable)
  • MMD = individual % more/less melee damage modifiers
  • MPD = individual % more/less projectile damage modifiers

All % values are expressed as decimal, e.g. 20% = 0.20. Reduced and less damage modifiers are expressed as negative values.

projectile_damage = tooltip_damage * (1.0 + IAD + IPD) / (1.0 + IAD + IMD) * (1.0 + MPD) / (1.0 + MMD)

If there are multiple more/less damage modifiers, then repeat the multiplicative terms (1.0 + MMD) and/or (1.0 + MPD) individually for each source.

tooltip_damage_melee = base_damage * (1.0 + IAD + IMD) * (1.0 + MMD)       (1)
tooltip_damage_projectile = base_damage * (1.0 + IAD + IPD) * (1.0 + MPD)  (2)

Divide (2) with (1) to eliminate base_damage

tooltip_damage_projectile / tooltip_damage_melee = (1.0 + IAD + IPD)/(1.0 + IAD + IMD) * (1.0 + MPD) / (1.0 + MMD) (3)

In order to be accurate, IAD, IMD, and IPD must be calculated correctly, including any effects from Strength and Iron Grip if applicable.

Note also that (3) is valid only individually for the physical or cold portions of the damage. In the presence of cold or elemental damage modifiers such as Fangs of Frost, HatredHatredAura, Spell, AoE, Cold
