Dead Onion is a passive item.

Effects[]

Notes[]

  • Although the description says "Toxic aura tears", the tears do not do toxic/poison damage.
  • Using Dead Onion in a Crawl Space will cause tears to fall through the floor.

Synergies[]

  • Added in Afterbirth15►Incubus Incubus: Does not affect shot speed or tear size, but still gives the piercing effect.
    • Added in Repentance: Shot speed, range, and tear size will be affected.

Interactions[]

  • Azazel Azazel: Not recommended. Range penalty is the only effect.
  • 15►Dr. Fetus Dr. Fetus: Not recommended. Bombs are slow to fire and will pass through enemies, making it far more difficult to hit them with explosions.
  • 15►Epic Fetus Epic Fetus: Overrides Dead Onion, although stat effects apply.
  • 15►Brimstone Brimstone: Overrides Dead Onion, although stat effects apply.
  • 15►The Ludovico Technique The Ludovico Technique: Not recommended. Tear moves very slowly making it hard to kill mobile enemies.
  • 15►Mom's Knife Mom's Knife: Overrides Dead Onion.
  • 15►Monstro's Lung Monstro's Lung: Fires a barrage of large tears that disappear at close range. Spectral and piercing effects make it very effective at close range.
  • 15►My Reflection My Reflection: Not recommended. Tears will travel a very short distance before they return to Isaac and eventually disappear.
  • 15►Proptosis Proptosis: Not recommended. While tears do massive damage at short range, it makes it a lot easier to be damaged by explosive enemies or enemies that do contact damage.
  • 15►Rubber Cement Rubber Cement: Edges of tears retain both piercing and spectral effects; however, the center of the tear will lose them and bounce.
  • Added in Afterbirth †15►Sulfuric Acid Sulfuric Acid: Not recommended. Acid Tears no longer impact objects and can no longer open Secret Rooms.
    • Added in Repentance Acid Tears can break objects (but still can't open doors or Secret Rooms).
  • Added in Repentance 15►Technology Technology: Laser size is increased.
