Attack Speed is the rate of a melee weapon's strikes. It is derived from three attributes: 

  1. The attack animation for the given weapon class
  2. The weapon's listed attack speed modifier
  3. Increases to attack speed from mods

Each general weapon type follows a standard attack animation which controls baseline striking speed. The polearm type has a slower standard attack animation than the sword type, for example. Specific weapons (such as the Cronus of the sword type) each have their own base attack speed modifier which alters the rate of the attack animation. An attack speed of 1.0 runs its attacks at default speed. An attack speed of 1.2 executes 20% faster, while a speed of 0.8 runs 20% slower. Attack speed is then further increased (or decreased) by attack speed mods and ability buffs, giving us the following basic equation:

Effective attack speed = standard attack animation * base attack speed * (100% + bonus attack speed)

Note that certain effects can further change attack speed in special ways. The Berserker mod, for example, multiplies the total attack speed value rather than adding to attack speed from mods.

Recall that attack animations vary between weapon types. Despite the Fragor (Hammer) and Karyst (Dagger) both having listed speeds of 0.8, the Karyst's actual speed is faster than the Fragor's due to daggers having a faster attack animation.

Faster attack speeds enhance a melee weapon's overall damage potential and utility by:

  • producing more strikes
  • hastening stance attacks which knock back or disable the target

Note that changes in attack speed do not apply to finishers, nor do they apply to charge attacks for most weapons. However, weapons with ranged charge mechanics such as the Glaive and Redeemer are affected, with faster speeds allowing for faster charge times.

Attack Speed ModsEdit

The following Mods affect Attack Speed positively, increasing a Melee Weapon's rate of attack:

The following Mods affect Attack Speed negatively, reducing rate of attack:

Attack Speed PowersEdit

The following powers affect Attack Speed positively, increasing a Melee Weapon's rate of attack:




(Volt) Speed: Increases Warframe Movement Speed and Melee Attack Speed. (Valkyr) Warcry: Increases Warframe Armor and Melee Attack Speed. (Harrow) Penance: Increases Ranged Fire Rate, Reload Speed and Melee Attack Speed.

Maximum Possible Attack SpeedEdit

This amounts to a maximum possible bonus of:

  • ~11.88x (1188%) for the average Warframe
  • ~11.97x (1197%) for the Fragor
  • ~12.07x (1207%) for Excalibur
  • ~12.17x (1217%) for the Lesion

*This does not account for Gladiator Vice, Harrow's Penance and Nidus' Power Strength buff
