Grants a brief moment of invincibility when the charge bar hits zero. If the spacebar is held for an additional second after hitting zero, Isaac will take damage.

Effects
Holding the spacebar will gradually deplete the charge bar. As the charge gets closer to zero, Isaac turns bluer over time.
Once the invincibility takes effect, Isaac starts flashing rapidly.

While not time based, invincibility from Breath of Life is otherwise identical to damage immunity granted by the shield effect.
The item will recharge on its own but cannot be used again until it is fully charged (even if you didn't fully deplete the charge bar).
