Berserk! is an activated item added in The Binding of Isaac: Repentance.

Effects

• When used, gives Isaac +0.4 speed and +3 damage and increases tears for 5 seconds, during which time he is restricted to using a jaw bone to damage enemies instead of his tears for 5 seconds, similarly to The Forgotten's bone club.
  • The jaw bone deals 3x Isaac's damage when swung and 1.5x Isaac's damage per tick when thrown (3x Isaac's damage per second).
  • While Berserking, Isaac's tear delay is multiplied by 2, then his tears fired per second is increased by 2. This will be a tears upgrade unless Isaac already has a lot of tears upgrades.
    • If playing as The Forgotten, the x2 tear delay modifier isn't applied, as he already has it.
  • Killing an enemy while "Berserking" increases Berserk's current duration by 1 second.
  • Isaac is unable to die while Berserk is active. He can be reduced to 0 hearts, but will not die until the effect ends.
• This item charges when Isaac deals damage to enemies rather than by clearing rooms or picking up batteries. It requires a total of 120 damage dealt to fully charge.

Notes

• The jaw bone has all the same synergies that The Forgotten's bone club does.

Trivia

• The item's name, description and effects are a reference to the Berserk power-up from the Doom franchise.
  • The phrase 'rip and tear' is frequently used throughout the Doom franchise, and was first used in the 1996 Doom comic after Doomguy picked up the Berserk power-up.
  • In addition, Isaac's inability to die during the effect is likely a reference to the common joke of the main character of the DOOM franchise being "literally too angry to die."
• The jawbone Isaac uses is a Donkey's jawbone, which is a reference to a passage from the Book of Judges in which Samson kills one thousand Philistines using only the jawbone of a donkey.
  • It may also be a reference to the item Donkey's Jawbone from Antibirth that didn't make the cut for Repentance.
