Azazel suffers from the shortest effective range of all characters; this is balanced with greater maneuverability provided by a flight and a high speed stat, additional power per hit via his Brimstone-like attack, and significant damage to all enemies in the room upon the loss of a Black Heart, killing most lesser enemies.
Due to his flight, Azazel takes damage only when leaving a Curse Room, not when entering, effectively letting him use these rooms at half-price. Additionally, he can use the Fool card he starts with to avoid the cost for one room entirely.
It is possible to slightly increase attack range by taking range-increasing items.
With enough range, acquiring homing tears will make Azazel's Brimstone home in on enemies.
20/20 doubles lasers without increasing tear delay.
Abaddon Aside from the lack of Angel Rooms, it provides no downside, given Azazel still has no Red Heart containers. As it costs 3 Soul Hearts, it will add 3 Black Hearts to his health bar, increase damage and speed, and give his Brimstone laser a fear effect.
This is no longer the case, as the amount of black hearts given by Abaddon is now based on the amount of red hearts it removes.
Brimstone gives Azazel the long-range version. It also increases fire rate since Brimstone's fire rate multiplier is x1/3 and Azazel's is x0.267.
His Brimstone laser takes longer to be fully charged but can be released anytime. Width and damage of the laser increases at higher charges. Width scales from 50% at minimum charge to 160% at maximum charge. Damage scales from 25% at minimum charge to 250% at maximum charge. Unlike with normal tears, the tears stat does not directly affect maximum or minimum damage.
Continuum: The range of Azazel's short Brimstone is increased and wraps around the screen, though without other significant range boosts it doesn't wrap far enough reach into the room.
Cricket's Body: Adds a scatter of blood tears from Azazel's Brimstone's landing point.
Eye of the Occult: Azazel's Brimstone becomes a lasso, auto-fired at a controllable target. Press Fire to start and Drop to stop.
Hemoptysis: Enemies hit by the sneeze will gain a curse that increases the damage Azazel's beam deals to 2x and +3 flat damage. Enemies who die to his beam under the curse will damage and spread the curse to nearby enemies.
Hook Worm allows the lasers to deal more damage per tick because of the shape it takes on.
The Ludovico Technique gives a Brimstone ring, whether Azazel has the short or long-ranged version of it, giving him the ability to damage many enemies at a time due to its size and negates Azazel's short-range, but halves Azazel's damage.
Marked: Azazel's Brimstone is auto-fired in the direction of a controllable target. Press Fire to start and Drop to stop.
Mom's Eye allows Azazel to shoot two beams, one of which is shot behind him.
Monstro's Lung gives several additional Brimstone beams around Azazel.
In the Bible, Azazel is the name given to the goat that was cast into the wild as part of Jewish atonement rituals. However, in certain traditions of Abrahamic religions, Azazel refers to the fallen angel who taught people to make weapons and jewelry and taught women the "sinful art" of painting their faces, as mentioned in the apocryphal Book of Enoch. Azazel is referenced three times in the Bible; this may be why he spawns with three Black Hearts.
Azazel's starting health is listed as "-1" on the character selection screen.
Azazel's locked character icon is a locked box with Azazel inside peeking out of it.
