Eye of Belial is an unlockable passive item added in The Binding of Isaac: Afterbirth †.

Effects

• +1.5 range.
• +1.0 tear height.
• Grants piercing tears.
• After piercing one enemy, tears will deal double damage and home in on enemies.

Notes

• The piercing effect makes placed Bombs, Troll Bombs, and Megatroll Bombs unable to be pushed around by Isaac's tears.

Synergies

• Godhead: Normal tears and Eye of Belial tears will retain damaging aura.
• Lachryphagy: Eye of Belial tears can still be fed and will burst, and burst Eye of Belial tears will still be homing. Tears from regular bursts can also turn into Eye of Belial tears.
• Lost Contact: Piercing through a projectile triggers the double damage and homing effect.
• Remote Detonator: Placed Bombs won't explode automatically, so they can be placed and have tears fired through them to activate double damage and homing.
• Technology Zero: All tears will be connected with electricity. Electricity will double in damage when the tears change.

Interactions

• Brimstone: Overrides Eye of Belial.
• Compound Fracture/ The Parasite/ Cricket's Body: Tears that pass through enemies will become Belial tears and split into smaller Belial tears. Non-Belial split tears can also turn into Belial tears if they pass through enemies.
• Diplopia: Only further increases range.
• Dr. Fetus: Piercing effect applies, but homing and doubled damage do not.
• Epic Fetus: Overrides Eye of Belial.
• Haemolacria: If the main tear pierces an enemy, it will turn into a Belial tear, and the burst tears retain the piercing effect and do double damage. If the main tear does not turn into a Belial tear, the burst tears will not be able to turn into Belial tears.
• Ipecac: Overrides Eye of Belial.
• The Ludovico Technique: Doubled damage does not apply if hitting the same enemy multiple times in a row. The controlled tear will continue to increase in size on every hit up to roughly the width of a single room, and the effect resets on changing rooms.
• Mom's Knife: Overrides Eye of Belial.
• Ouija Board: Eye of Belial tears lose their homing ability and fly offscreen.
• Pop!: Homing tears will only damage the enemy once and then just remain fixed above the target for a brief amount of time until disappearing.
• Technology: Overrides Eye of Belial.
• Technology 2/ Tech.5: The lasers are not affected by the Eye of Belial; however, the tears apply the effect normally.
• Tech X: Overrides Eye of Belial.
• Tractor Beam: May seem to override Eye of Belial but if a homing tear finds a target to seek it will stop midair as if it were fighting its momentum.
• Trisagion: Overrides Eye of Belial.

Trivia

• Belial is a term from the Hebrew Bible referring to the devil.
