Lead Pencil

Lead Pencil is a passive item added in Afterbirth †.

Effects

 * After every 15 tears fired, Isaac will fire a Monstro's Lung-like barrage.
 * Tears in the barrage deal double damage.
 * Tears will fire only from Isaac's right eye.

Interactions

 * 20/20/The Inner Eye/Mutant Spider/Conjoined (Transformation): The effect counts tears, not shots, and occurs on one of the tears of the salvo, not all of them.
 * Brimstone: Overrides Lead Pencil.
 * Cricket's Body: All tears from the barrage split, covering a large area.
 * Dr. Fetus: Overrides Lead Pencil.
 * Ipecac: A barrage of Ipecac tears are fired that land right next to Isaac, hitting him.
 * Lilith: No effect, as Lilith is inherently Blindfolded.
 * Incubus: Fires like Blood Clot with Cain, having a chance to fire a shot that does increased damage.
 * Mom's Knife: Overrides Lead Pencil.
 * Monstro's Lung: Effect will be intermingled with normal Monstro's Lung shot.
 * Technology: Overrides Lead Pencil.
 * Technology 2: Overrides Lead Pencil and disables normal tears entirely, even if not playing as Cain.
 * Tech X: Overrides Lead Pencil.
 * The Ludovico Technique: Overrides Lead Pencil
 * Loki's Horns: Lead Pencil can fire in any of the cardinal directions if it fires at the same time as Loki's Horns.

Trivia

 * Though the pencil is in Isaac's right eye, it blocks tears from firing out of his left eye.
