Lead Pencil

Lead Pencil is a passive item added in The Binding of Isaac: Afterbirth †.

Effects

 * After every 15 tears fired, Isaac will fire a low range Monstro's Lung -like barrage of 12 tears.
 * Tears in the barrage deal double damage.
 * Tears will fire only from Isaac's right eye.

Synergies

 * //: All tears from the barrage split.
 * Fires a barrage of Haemolacria tears, all of which will burst.
 * Tears tend to clump together, becoming one giant tear which splits into 8 large tears. When tears burst, they can also spawn barrages of tears that can be fed.
 * Causes burst tears to remain in the room for much longer, forming a soft barrier of sorts, which enemies must survive through to reach Isaac.
 * Torn Card: Decreases shot requirement by 1. Lead Pencil will fire every 14th shot, with Torn Card quickly following at 15th.
 * Fires a barrage of beams.
 * All tears benefit from the damage bonus granted by The Scooper.
