Dead Eye

Dead Eye is a passive item added in Afterbirth.

Effects

 * Isaac's damage increases for each successive tear hit on enemies.
 * The multiplier increases by 0.125x for each hit, going up to a maximum of 2x after 8 successive hits.
 * If a tear misses and hits nothing (wall/floor), there is a chance for the multiplier to be reset back to 1.
 * The chance is 20% for the first miss, 33% for the second miss, and 50% for the third miss and beyond.
 * As the multiplier increases, Isaac's tears glow red and increase in size.

Interactions

 * : No effect.
 * : Split tears that do not hit enemies are considered misses, nearly guaranteeing losing the multiplier.
 * : Split tears that do not hit enemies are considered misses, nearly guaranteeing losing the multiplier.
 * : No effect.
 * The Forgotten: The Forgotten's swing increases the multiplier when successfully hitting enemies, resets the multiplier upon swinging and missing. The multiplier changes normally when firing tears as The Soul, and the two forms share the same multiplier.
 * : Tears fired by the Host are affected by Dead Eye.
 * : Incubus's tears do not affect the multiplier, but Incubus can gain damage from Isaac's normal tears increasing the multiplier. The familiar's tears do not reset the multiplier if they miss, either.
 * + : Tears fired by Incubus are now affected by Dead Eye.
 * Lilith: Because she cannot normally fire tears, Dead Eye has no effect.
 * Lilith + : Lilith is able to control a tear and is able to gain the damage up from Dead Eye.
 * : If the tears fired by Isaac's Tears miss, they cause the multiplier to reset.
 * : Multiplier is gained even faster.
 * : No effect.
 * : Isaac will shoot an inaccurate burst of tears, meaning many tears will miss and the damage boost will be reset frequently.
 * Piercing Tears: Not recommended, as tears that travel through enemies may still count as misses.
 * : Tears that hit enemies may bounce off and still count as misses.
 * : Due to the extreme increased in rate of fire, building up the damage multiplier is faster but misses are much more frequent.
 * : Tech X overrides the effects of Dead Eye and damage stays at the 2x multiplier.
 * : No effect.
 * : No effect from the laser itself, but the tears fired from the second eye are affected by Dead Eye.

Synergies

 * : If both tears hit, they both contribute to the damage multiplier.
 * : Charging tears makes it easier to avoid missing.
 * + : Successfully hitting enemies with the Chocolate Milk shots will increase the damage of the Technology 2 laser.
 * : All of Isaac's stats increase for each successive tear hit on enemies.
 * : Damage bonus increases until it hits the max of 2x. Since the controllable tear never hits the ground or wall, the bonus cannot be lost.
 * Petrification/Slow items: Enemies will be petrified or slowed, making them easier to hit without missing.
 * : Isaac's tears become much larger, making it easier to avoid missing.
 * : Tears are larger and easier to hit with at low range. Additionally, if the tear fades out of existence instead of running out of range, it does not count as a miss.
 * : Isaac's tears no longer hit walls and stay in the air for longer, allowing many damage amplified tears to be fired before the damage boost is lost

Trivia

 * The item is a reference to the Bullseye.
