Neptunus

Neptunus is a passive item added in The Binding of Isaac: Repentance.

Effects[edit | edit source]

When Isaac is not firing tears, a charge bar will start to fill up. Holding down the fire button will release all stored tears in rapid succession.
- The charge time and maximum tears per charge scale with Isaac's tears stat, with higher tears charging faster and having more.

While at 0 charge, Isaac fires at his normal tear delay, essentially meaning there is no downside.
This item has no observable effect when used as Tainted Lilith.
