Proptosis is a passive item.

Effects[edit | edit source]

  • Removed in Repentance Doubles Isaac's damage stat.
  • Added in Repentance +0.5 damage.
  • Tear size multiplier: 2x.
  • Removed in Repentance The tears shrink and lose damage the farther they travel.
  • Added in Repentance The tears shrink and lose damage the more time they stay airborne, starting at 3x damage at point blank range. After a fixed period of time, they deal no damage at all.

Notes[edit | edit source]

  • Removed in Repentance Effective range of Isaac's tears now also depends on the damage, as they can shrink out of existence before their air time runs out.
  • Added in Repentance Since tears run out of damage after a fixed amount of time, shot speed is the only stat that determines the effective range of Isaac's tears. Damage and range don't affect the travel distance at all.
  • Removed in Repentance Tear size increasing items also increase the maximum distance before its disappearance, but the damage dealt can go below original at the extreme.
  • The item has the opposite effect of the item 15►A Lump of Coal A Lump of Coal, which makes Isaac deal more damage from farther away.
  • Removed in Repentance Does not affect Azazel Azazel short-ranged 15►Brimstone Brimstone unless the range stat is extremely high.

Synergies[edit | edit source]

  • 15►Anti-Gravity Anti-Gravity: The tears will not decrease in size or damage until they start moving, making this excellent against enemies that chase Isaac.
    • With Added in Repentance15►Eye of the Occult Eye of the Occult, this synergy becomes even stronger as it lets Isaac deal the full 3× damage multiplier while maintaining control of his tears.
  • 15►Brimstone Brimstone: Retains the double damage effect without losing damage over range.
    • Added in Afterbirth Damage is doubled again for a total of 4x next to Isaac, but quickly drops further along the beam, at about 0.8x per tile of distance.
    • Added in Repentance The beam does 6x damage at point blank range.
  • 15►Dr. Fetus Dr. Fetus/15►Epic Fetus Epic Fetus: Doubles damage with no penalty for distance.
  • 15►Godhead Godhead: The damaging halo shrinks with the tears.
  • 15►A Lump of Coal A Lump of Coal: Proptosis scales with Isaac's damage while the Lump of Coal does not. At base damage, the Lump of Coal will approximately negate the damage lost over distance, but with increased damage, tears still do more damage up close.
    • A Lump of Coal + 15►The Ludovico Technique The Ludovico Technique: The controlled tear has full Proptosis damage buff, no matter how far they are from Isaac.
  • 15►Mom's Knife Mom's Knife: The Knife damage is doubled regardless of range.
  • 15►Polyphemus Polyphemus: Tears do massive damage and carry with leftover damage while still shrinking.
  • 15►Technology Technology/15►Technology 2 Technology 2: Doubles damage.
    • Added in Afterbirth The beam decreases in damage and width the farther it travels. Tears become virtually powerless across large rooms like the Boss Rush and the Hush fight.
    • Added in Repentance The beams do 6x damage at point blank range.
  • Added in Afterbirth15►Tech X Tech X: Ring size and damage is substantially increased, but decreases as the ring travels further from Isaac.
  • Added in Afterbirth †15►Trisagion Trisagion: Base damage is doubled and beam damage is boosted to about 65%. Blasts lose no power as they travel further, though the tips of the blasts deal very slightly less damage.

Interactions[edit | edit source]

  • Added in Afterbirth15►Athame Athame/Added in Afterbirth15►Maw of the Void Maw of the Void: The ring is much larger and deals 1.5× damage.
    • Added in Afterbirth † The ring deals normal damage.
    • Added in Repentance The ring is now normal size.
  • Added in Afterbirth †15►Compound Fracture Compound Fracture/15►Cricket's Body Cricket's Body/15►The Parasite The Parasite: Tears will often disappear before they can burst. Tears created from bursts will also shrink, but due to their already low range, the difference may not be noticeable.
  • Added in Afterbirth †15►Flat Stone Flat Stone: At base range and tear size, tears will bounce twice against the floor and then disappear.
  • Added in Repentance15►Immaculate Heart Immaculate Heart: Tears that appear around you disappear quickly.
  • 15►Ipecac Ipecac: Tears almost disappear completely but are still able to do massive damage.
    • Added in RepentanceTears no longer deal massive damage at the end of the arch. Damage decreases rapidly with range.
  • Added in Afterbirth †15►Lachryphagy Lachryphagy: Tears disappear too quickly to be fed.
  • 15►The Ludovico Technique The Ludovico Technique: The closer the tear floats to Isaac, the larger it is. The farther away, the smaller it becomes.
  • 15►Monstro's Lung Monstro's Lung/Added in Afterbirth †15►Lead Pencil Lead Pencil: Tears will disappear at different distances depending on how big they were when fired.
  • 15►My Reflection My Reflection: Tears disappear before they can return to Isaac.
  • Added in Afterbirth †15►Pop! Pop!: Tears will disappear extremely quickly after being fired.
  • 15►Soy Milk Soy Milk: Very poor combination. Tears disappear nearly instantly in front of Isaac, decreasing his range and damage to nearly nothing.
    • Added in Repentance Tears no longer disappear instantly. Range is only minimally shorter.
