Glass Cannon

Glass Cannon is an activated item added in Afterbirth.

Effect

 * Fires a single high-damage piercing tear which can travel over obstacles.
 * Sets the player's health to half a heart (half a soul heart if these are present but there are no heart containers). This also removes any other soul or black hearts, but not eternal hearts.

Synergies

 * Car Battery - Fires two tears.
 * Chocolate Milk - The current charge of Chocolate Milk affects Glass Cannon; however, it seems it will charge even past the maximum charge point, causing larger than room-sized tears if a tear button is held down for 5-10 seconds depending on damage and charge time.
 * Rubber Cement - The tear bounces off obstacles and enemies.
 * Spoon Bender - The Cannon's tear homes in on enemies.
 * Whore of Babylon - Affects the Cannon as it would tears, only the item is in effect as long as the Glass Cannon is used.
 * Pupula Duplex - Affects the Cannon as it would tears, resulting in a very wide shot.
 * Ipecac - The tear produced by glass cannon becomes explosive and has the effect of poisoning on the enemy used against.

Trivia

 * Glass Cannon is a term used in video games for someone or something that deals high amounts of damage but has very low defense.
