Notes
Although it is difficult to hit enemies with Abel, he can be useful in certain situations. Doples and Evil Twins can be easily taken care of without risk of damage using Abel. Abel can also assist in killing slow or stationary monsters that happen to be around the center of the room.
In symmetrical room layouts Abel can be used to clear away destructible obstacles such as fire places and poops.
According to the Bible, Abel was one of Adam and Eve's children and was the first human to ever be murdered. He was an opposite to his murderous brother Cain, which may explain the mirrored nature of this item. Also, this item is unlocked by defeating The Lamb with Cain, which makes the connection with the Bible more obvious.
This item was originally unlocked in Wrath of the Lamb by defeating Isaac as Cain.
