Effects

  • Greatly increased damage: (Damage+4)×2
  • (except in Repentance and Repentance+) Tears down: (Delay×2.1)+3
  • (in Repentance and Repentance+) Tears fired per second * 0.42.
  • If a tear kills an enemy and has left over damage, the tear travels on with the remaining damage.

Notes

Synergies

  • (in Repentance and Repentance+)Collectible Abyss icon.pngAbyss: When Polyphemus is picked up instead of being converted into a locust, it grants all of Abyss's locusts the high damage up without suffering the tears down allowing Isaac to increase his damage rate substantially the more items he uses Abyss on.
  • Collectible Dr. Fetus icon.pngDr. Fetus: Increases tear delay, and after the first bomb explodes, a second bomb appears where the first one exploded, doing roughly half the damage of the first.
  • Collectible The Inner Eye icon.pngThe Inner Eye/Collectible Mutant Spider icon.pngMutant Spider/(in Repentance and Repentance+)Collectible C Section icon.pngC Section: The tear rate is not lowered further, but the effect on damage becomes a flat +5 bonus instead.
  • (except in Rebirth and Afterbirth) Character The Forgotten icon.pngThe Forgotten: The Forgotten's bone club becomes massive. It deals very high damage but has a very low swing rate.
  • (in Repentance and Repentance+)Collectible Rock Bottom icon.pngRock Bottom: Allows Isaac to keep his previous fire rate in addition to the massive damage boost.
  • (in Repentance and Repentance+)Collectible Shard of Glass icon.pngShard of Glass: The rapidly spawning red tears do full damage.

Interactions

  • (except in Rebirth and Afterbirth)Collectible Haemolacria icon.pngHaemolacria: The main tear retains the semi-piercing ability and may not burst when hitting a weaker enemy. Split tears do not semi-pierce.
  • (except in Rebirth and Afterbirth)Collectible Lachryphagy icon.pngLachryphagy: Greatly increases how big the fed tear can grow.
  • Collectible Lost Contact icon.pngLost Contact: Isaac's tears will block enemy shots and continue, but lose 10 damage. If the tear had less than 10 damage left, it disappears.
  • Piercing tears: Semi-piercing is replaced by proper piercing, with no loss of damage on any enemy contact.
  • Collectible Polyphemus icon.pngPolyphemus: No further effect when multiple copies are acquired.
