Spawns a demonic familiar that copies Isaac's tears.
Incubus' tears ignores Isaac's range and shot speed.
Incubus' damage is reduced by 25% when playing as characters other than Lilith.
Lilith's starting Incubus is technically not a collected item but an intrinsic part of the character, and is removed if an item such as Ankh or Clicker are used to become a different character. As such, playing as Lilith will not add Incubus to the collection page.
If an Incubus is acquired through Cambion Conception or by starting with it as Lilith, another Incubus can still be found normally. Lilith can also receive one from Cambion Conception in addition to the one she starts with, and if this occurs, Box of Friends will produce only one extra Incubus.
Incubus has the second highest priority of following familiars, below King Baby.
This item belongs to the Conjoined set. Collecting three items from this set will transform Isaac into a three-faced version of himself. Lilith's Incubus, however, does not count towards the transformation.
Azazel / Brimstone: Fires a full length Brimstone laser that can be charged while still firing the previous laser, allowing it to fire more rapidly than normal.
The laser fired by Incubus has the same width as Lil Brimstone's.
When playing as Azazel, Incubus' Brimstone laser has the same range as him.
BFFS!: Deals double/ 1.5x Isaac's damage. Still deals 2x damage as Lilith.
In folklore, incubi are evil spirits said to descend upon sleeping people, specifically ones fabled to have sexual intercourse with women during their sleep, or, more simply put, the male version of a succubus.
