Glass Cannon is an activated item added in The Binding of Isaac: Afterbirth.

Effects[]

  • Fires a single high-damage piercing tear which can travel over obstacles.
    • The damage dealt by this tear is ten times Isaac's damage, plus a flat 10 damage.
    • The shot has an additional 1.5x size multiplier on top of damage-increased size.
  • Removed in Repentance Sets Isaac's health to half a heart with each use (half a Soul Heart if these are present but there are no Red Heart containers). This also removes any other Soul Heart Soul Hearts or Black Heart Black Hearts, but not Eternal Heart Eternal Hearts.
    • Added in Afterbirth † / Removed in Repentance If Isaac has no Red Hearts and at least one Added in Afterbirth † Bone Heart Bone Heart, only an empty Bone Heart remains.
  • Added in Repentance Upon taking damage, this item turns into Added in RepentanceBroken Glass Cannon Broken Glass Cannon, and Isaac will lose an additional 2 hearts of health on top of the damage he already took. Isaac gains 1.5 range and leaves a trail of red creep behind him, identical to the effects of Anemic Anemic for the rest of the current room.
    • If the damage from breaking Glass Cannon would result in death, Isaac will remain at half a heart, gaining half a soul heart if necessary. This does not apply if the damage Isaac took would be lethal before the extra damage is taken.
    • Self-damage (e.g. from Blood Donation Machine.png Blood Donation Machines) will not break Glass Cannon.

Notes[]

  • Glass Cannon can be fired diagonally, even without Added in Afterbirth †Analog Stick Analog Stick.
  • Shooting the Glass Cannon gives a slight knockback effect to Isaac, which can be dangerous in rooms with obstacles like spikes or Fire Places.
  • Getting hit while playing Keeper Keeper will result into a second coin heart being damaged on top of the damage he already took.

Synergies[]

  • Added in Afterbirth †Lachryphagy Lachryphagy: Glass Cannon will fire giant Lachryphagy tears. Tears are harder to feed as they will burst very quickly but they can be fed if you fire tears beforehand and then fire Glass Cannon into those tears.

Bugs[]

Bug Bug! Removed in Repentance Glass Cannon can be used to steal Devil Room items by using it to set your health to Removed in Afterbirth † half of a Soul Heart or Added in Afterbirth † no health at all before you die. In the latter case, picking up any item that isn't a health upgrade will kill Isaac.
Bug Bug! Added in Repentance If Tainted Forgotten Tainted Forgotten takes damage with the cannon held above his head, he will be unable to fire and unable to attack. Exiting and continuing will fix this.
