Dead Onion is a passive item.

Effects

• Grants piercing and spectral tears.
• +0.25 range.
• -1.5 range.
• -0.4 shot speed.
• -0.5 tear height.
• Tear size multiplier: 1.5x.
  • +0.22 tear size.

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

• Incubus: Does not affect shot speed or tear size, but still gives the piercing effect.
  • : Shot speed, range, and tear size will be affected.
• Lost Contact: Tears will destroy enemy projectiles without being destroyed in the process.

Interactions

• Azazel: Not recommended. Range penalty is the only effect.
• Dr. Fetus: Not recommended. Bombs are slow to fire and will pass through enemies, making it far more difficult to hit them with explosions.
• Epic Fetus: Overrides Dead Onion, although stat effects apply.
• Brimstone: Overrides Dead Onion, although stat effects apply.
• The Ludovico Technique: Not recommended. Tear moves very slowly making it hard to kill mobile enemies.
• Mom's Knife: Overrides Dead Onion.
• 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.
• My Reflection: Not recommended. Tears will travel a very short distance before they return to Isaac and eventually disappear.
• 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.
• Rubber Cement: Edges of tears retain both piercing and spectral effects; however, the center of the tear will lose them and bounce.
• Sulfuric Acid: Not recommended. Acid Tears no longer impact objects and can no longer open Secret Rooms.
  • Acid Tears can break objects (but still can't open doors or Secret Rooms).
• Technology: Laser size is increased.

Trivia

• Dead Onion has the most stat downs out of any other item if tear height is counted as a stat.
