Mother's Kiss

Mother's Kiss is a trinket added in The Binding of Isaac: Repentance.

Effects

 * Grants one heart container while held.
 * This heart container will be filled the first time the trinket is picked up.

Synergies

 * : The trinket will be consumed but you get to keep the soul hearts from the conversion.
 * : Adds 2 heart containers.
 * ///: If Mother's Kiss is picked up while having 12 Soul/Black Hearts, Mother's Kiss will not trigger until damage is taken. However, if only half a heart of damage is taken, Mother's Kiss will immediately restore the health back to a full 12 but believe its effect failed due to not restoring a full heart's worth, allowing it to trigger again and again until a full heart of damage is taken, after which it will cease taking effect. If combined with, this makes any of the above-mentioned 4 characters virtually invincible as long as their health is not reduced in any way through Devil Deals, Health Down pills, etc.
