Effects[ | ]

  • (except in Repentance) Adds a chance to fire piercing tears which will instantly kill any non-boss enemy.
  • (in Repentance) Adds a chance to fire a tear that summons Boss Big Horn ingameBig Horn's hand. It will grab and crush any non-boss enemy, killing them instantly, and attacks bosses 3 times for 12 damage each hit (even Boss Big Horn ingameBig Horn himself).
    • Boss Big Horn ingameBig Horn's hand is able to push projectiles of enemies away from the source of contact. These tears gain additional speed. This makes it especially difficult for the player to dodge while fighting Boss Hush ingameHush, as it fires a lot of tears and many are propelled by a turning force.
  • Running into enemies deals 3.5 damage to them.
    • Damage is dealt up to twice per second per enemy.

Notes[ | ]

  • The chance to fire special tears depends on the luck stat, and the formula used to determine the chance is:
    • At base luck (0), the chance is 5%, maxing out at 20% at 15 luck.
  • The special tears will kill some normally invulnerable monsters, such as Death's HeadDeath's Heads, StoneyStoney, and Boss Peep ingamePeep's floating eyeballs.
