Proptosis is a passive item.

Effects[edit | edit source]

  • Doubles Isaac's Damage stat.
  • Isaac's tears become larger and do more damage, but shrink and do less damage the further they travel.

Notes[edit | edit source]

  • Effective range of Isaac's tears now also depends on damage, as they can shrink out of existence before their air time runs out.
  • Tear size increasing items also increase the maximum distance before disappearance, but the damage dealt can go below original at the extreme.
  • The item has the opposite effect of the item A Lump of Coal, which makes Isaac deal more damage from farther away.
