Berserker

Not to be confused with the Berserker Warframe, Valkyr.

The Berserker mod increases a melee weapon's attack rate by 5% for 4 seconds per rank on a critical hit. At rank 5 this amounts to a 30% attack rate increase for 24 seconds.

Tips

 * This mod can benefit high critical weapons such as the Kogake, Obex, Dual Ichor, Dual Zoren, Dual Cleavers, Atterax, Scindo Prime and fast weapons like the Fang and its Prime variant, allowing a far faster attack speed.
 * This mod synergizes well with True Steel and/or True Punishment, as the increase in critical hit chance will make it more likely for this mod to activate.
 * Finishers will count as a critical hit and activate this mod.

Trivia

 * Prior to Update 13.8.1 Berserker appeared to treat the melee Stealth damage bonus as a critical hit, activating or refreshing the speed bonus. As a result, abilities like Smoke Screen, Invisibility or Radial Blind would synergize well with this mod.
 * This mod was previously acquirable from Tenno Specters. However, as of Update 14.6.1, Berserker mods that are dropped by Tenno Specters are not added to the player's inventory when the mission is finished.
