Ring Worm

Ring Worm is a trinket.

Effects

• Isaac's tears travel in a high-speed spiral pattern.

Notes

• The tear pattern slightly increases Isaac's effective range.

Interactions

• Bob's Rotten Head

  Upon use, Isaac holds a poison bomb which can be thrown towards any of the four cardinal points and explodes on impact.

  : When thrown, the head follows the same high-speed pattern as Isaac's tears.
• Brimstone

  Tears are replaced by a laser beam that pierces through all enemies and obstacles in its path and deals high damage. Can only be fired after a short charge-up period.

  : No effect.
• Dead Onion

  Grants piercing and spectral tears. Increases tear size (without increasing damage) while greatly reducing range and shot speed.

  : Tears move very fast, negating the slow speed and poor range.
• The Ludovico Technique

  Instead of firing tears, Isaac controls one floating tear that hover over obstacles. This tear deals constant damage when held in place over an enemy.

  : The tear moves uncontrollably, making it rather difficult to hit enemies.
• Mom's Knife

  Isaac's tears are replaced by a knife that pierces enemies, can travel through obstacles, and can hurt enemies while Isaac is holding it. Holding down the fire button before firing increases its range and power.

  : No effect.
• Monstro's Lung

  Increases damage and grants a charged shot that fires multiple tears in the same fashion as Monstro.

  : Tears spin as a cluster, making it difficult to hit enemies.
• Technology

  Replaces tears with a piercing laser with unlimited range.

  : No effect.
• Tiny Planet

  Range up and makes shot tears revolve around Isaac until they drop.

  : Tears spin uncontrollably fast, making it incredibly difficult to aim.
• Strange Attractor

  Pickups, trinkets, and monsters are magnetically attracted to Isaac's tears.

  : Items and enemies are drawn more to the tear path rather than Isaac.

Trivia

• The shot pattern might be a reference to NES Uncle Fester's Quest power-up.
• Ring worm (or Dermatophytosis) is a fungal infection very common in children and adolescents. It involves scaly rings on the skin of the scalp, chest, arms, stomach and other places. It gets its name not from being caused by a worm, but from its ringed pattern the infection causes.
