(in Afterbirth † and Repentance)

Sinus Infection is a passive item added in Afterbirth †.

Effects

  • Grants a chance to fire a booger that sticks to an enemy and deals damage over time.
    • Multiple boogers can stick to one enemy to deal extra damage.
    • Each booger deals damage equal to Isaac's tear damage every second.
    • The booger lasts for 60 seconds or until the enemy dies.
    • Boogers cannot pierce and stick to the first enemy that they come in contact with.

Notes

  • The booger falls off the enemy after they die. If it hits another enemy before it touches the ground, it will stick to them and deal damage.
  • Jumping enemies or bosses like Monstro and Leapers and burrowing enemies like Round Worms and Lumps can get rid of the booger when they leap or burrow.
    • Bosses like The Harbingers or Dark One, or enemies like Oob that have dash attacks do not lose the booger when they go off-screen.
  • The tear sticking effect is similar to Collectible Explosivo iconExplosivo's.
  • Booger shots behave like piercing shots against bombs and fireplaces, making it potentially difficult to evade hostile bombs or push your bombs along.
  • The Nose GoblinNose Goblin trinket's effect is almost identical to Sinus Infection, with an added homing bonus.
    • The effects have independent chances to proc. If Isaac has both, there is a chance to fire either homing or non-homing boogers.
  • Not affected by Luck.

Synergies

  • Collectible Cricket's Body iconCricket's Body: Booger tears will split into split booger tears that can attach to enemies.
  • Collectible Godhead iconGodhead: Shots retain their aura while stuck to an enemy, but the aura can damage only enemies other than the booger victim. If the enemy dies while duration remains, it will resume homing and will often stick to a second enemy.
  • Guppy: Every damage instance that a booger shot does while attached to an enemy will trigger a fly to spawn.
  • Collectible Lachryphagy iconLachryphagy: All tears have a chance to burst into boogers. Boogers will always burst into more boogers, though some of the boogers may incorrectly appear to be normal tears. When a booger sticks to an enemy, it will burst into 8 boogers which have a high chance of sticking again to the same enemy.
  • Collectible Lost Contact iconLost Contact: Boogers that stick to enemies will block shots, and will not be destroyed in the process.
  • Collectible Polyphemus iconPolyphemus: Booger shots lose the Polyphemus pierce effect, but stick to enemies while dealing the full damage of the Polyphemus shot. Damage does not degrade.
  • Collectible Strange Attractor iconStrange Attractor: Attraction effect will remain on the booger shot stuck to an enemy. This can drag the enemy across the whole room until they reach one wall and get stuck on it, effectively disabling their normal movement.
