Euthanasia

Euthanasia is an unlockable passive item added in Afterbirth †.

Effects

 * Adds a chance to fire needles which deal triple Isaac's tear damage.
 * Needles will instantly kill regular enemies and cause them to burst into 10 more tears in all directions.
 * The chance to fire a needle depends on luck and goes up to 100% at 15 luck.

Synergies

 * /: Allows harvesting black hearts from Stone Grimaces as they can be (invisibly) poisoned by touching them, then destroyed with Euthanasia.
 * : Does not override the tear burst and retains the chance for triple damage, but doesn't change the tear appearance. When killing an enemy, ten Haemolacria tears are fired which can burst into smaller tears.
 * : Does not override the tears burst, retains the chance to do triple damage, and retains Euthanasia tear appearance. Needles from Lachryphagy bursts can activate Euthanasia bursts, and all needles fired by Euthanasia bursts can be fed and will burst.
 * /: Each tear in the barrage may become a needle, which retains all Euthanasia effects.
 * : Does not override the tear burst and retains the chance for triple damage, but tear appearance doesn't change.

Interactions

 * : Overrides the tear burst, retains the chance for triple damage but does not change the appearance of the laser. Does not retain ability to kill normally unkillable enemies.
 * : Bones will split up as normal, and upon touching an enemy, will burst into 10 bones which will all split. Bones and bone fragments have a chance to deal triple damage (bone fragments deal 50% of Isaac's tear damage by default), and they will instantly kill normal enemies.
 * : Needle tears will split into 4 small needle tears upon hitting the ground or an enemy. Split tears produced have chance to deal triple damage, but will not cause tear bursts.

 * : Overrides the tear burst, retains the chance for triple damage but does not change the appearance of the missiles. Does not retain ability to kill normally unkillable enemies.

 * : Overrides the tear burst, retains the chance for triple damage with large, explosive needles. Does not retain ability to kill normally unkillable enemies.
 * : When needles are fired, they don't seem to grow in size; however, they will increase in damage as they travel. Burst needles will increase in size and damage.
 * : Some needle tears gain the piercing, instant kill effect and orange glow. When these tears pass through and kill an enemy, they do not burst into more tears.
 * : Overrides Euthanasia.
 * : Both regular tears and parasite split tears will cause enemies to burst into tears, with a chance to deal triple damage and kill normally unkillable enemies.

Trivia

 * Euthanasia is the act of intentionally ending a person or animal's life in order to end their pain and suffering. It is usually carried out by an injection, hence why this item has the appearance of a needle.
 * Euthanasia is the only syringe item that points upwards; all of the other syringes point downwards.
 * Euthanasia and Experimental Treatment are the only 2 syringe items that need to be unlocked.
