Template:Leviathan

Notes

The chance to fire a fear tear depends on Isaac's Luck stat, and goes up to 100% at 85 Luck.
Does not remove soul hearts.
As it removes all red heart containers, other devil deals can be taken for "free" as long as Abaddon is taken last while still having at least 1 container.
Has no negative trade-off when taken as ???, except the revoked chance of an angel room.
Since Keeper is not allowed to have Soul or Black Hearts, Abaddon will simply take away all his health coins; resulting in instant death.
Can always be taken when offered as a 3 soul heart devil deal. Even if the player only has one or two soul hearts, six black hearts will be granted after taking the item.

Synergies

Empty Vessel: Since Empty Vessel activates when all red hearts are lost, it will activate as soon as Abaddon is picked up.
Whore of Babylon: Since Whore of Babylon is active at half a red heart or less, it will activate as soon as Abaddon is picked up.

Trivia

In the Hebrew Bible, the name Abaddon is used in reference to a bottomless pit, often appearing alongside the place of the dead (which is known as Sheol), meaning the land of the dead. The actual Hebrew word Abaddon (אבדון - pronounced avadon) means "doom".
Abaddon is the Hebrew equivalent of Apollyon.
In the New Testament Book of Revelation, an angel called Abaddon is written as the king of an army of locusts; his name is first transcribed in Greek (Revelation 9:11 – "whose name in Hebrew Abaddon").
