Fiend

## Description

Fiend is a glass cannon character that uses his health to fight for him.

He starts with XVII - The Stars.

## Abilities

His main ability and at the same time his gimmick is using his own hearts as familiars that attack enemies.

* When Fiend takes damage while the room is uncleared, he will lose all its health except half a Black Heart and several of his Friends - small black fiend familiars - will spawn.
	+ For each full black heart lost, a normal Friend is spawned. When the room is cleared, every Friend will disappear and leave a black heart for Fiend to retrieve.
	+ If Fiend had a whole number of hearts (thus losing an extra half heart), an extra Hollow Friend will spawn. These don't drop a black heart when they disappear.

* The familiars will follow enemies and deal contact damage to them. The damage scales with player's Damage at about 20% of its value.
	+ Extremely rarely, a familiar can land a critical hit that deals 5 times player's Damage. Scales with luck.
	+ The familiars behave like morsels, and can't fly over obstacles unless Fiend can.

* If there are no enemies in the room or if the room is already cleared (the doors are open), no familiars will spawn and Fiend will keep his health as usual.

Fiend works somewhat like Blue Baby and cannot have red hearts.

* Any items that would give him red heart containers will give Black Hearts instead.

* All red heart drops have chance, that scales with Luck, to become Black Hearts.
	+ At 13 Luck, that chance becomes capped at about 66%.
	+ This includes drops from items like Little C.H.A.D.
	+ Fiend Folio adds Half Black Hearts, which can replace half red hearts, while full Black Hearts replace full versions.
	+ Some special heart types have 100% chance to convert into Black Hearts. These types are: Soul, Golden, Blended and Eternal.
		- Bone Hearts have a fixed 20% chance to be replaced by full Black Hearts
		- Half Soul Hearts are supposed to be replaced by Half Black Hearts but due to a bug, they become full Black Hearts.
		- Fiend can get Eternal Hearts through other means though, like Fate for example.
			* They work as expected, giving a Black Heart when combined.
			* Eternal Hearts will never convert in Angel Room-themed Super Secret Rooms.

* Fiend has unique interaction with Bone Hearts. He cannot collect them like Blue Baby but instead, they will be converted into multiple bone orbitals, like those created from Book of the Dead.

By enabling it in options, Fiend can start with a secondary ability - Fireballs.

* When in an uncleared room, Fiend will slowly regenerate Fireballs that will orbit around him.
	+ Frequency of Fireball regeneration scales with player's Fire Rate.
	+ Player can have up to three Fireballs.
* By doubletapping one of the attack buttons, one of the Fireballs will detach from its orbit and will be launched in desired direction.
	+ Fireball deals triple player's Damage.
	+ The Fireball has increased shot speed and while travelling, will leave small flames behind that deal half of player's Damage.
	+ Fireball has homing but due to its high shot speed, it's less noticeable.
	+ The Fireball explodes upon contact with an enemy or with an obstacle.
		- The explosion can destroy rocks and creates a small ring of flames that deal half of player's Damage.

By enabling classic tears in the options menu of the mod, Fiend gains homing tears with a unique look.

Fiend has an increased chance to find Cursed Pennies.

## Trivia

* Lil Fiend and Fiend's Horn spawn Hollow Friends - variants of Fiend's familiars that do not drop Black Hearts upon clearing the room.
* Fiend was planned to have unlockables, but it was scrapped before the release of Fiend Folio.
* Fiend is a returning character from Devil's Harvest - one of many mods that merged with Fiend Folio.
* Fiend himself is based off the Smiling Imp emoji - specifically, the one that Twitter/Discord uses.
* Fiend shows his provocative, but very much iconic middle finger when performing his "thumbs up" animation.
* If player acquires the Beelzebub transformation as Fiend, his appearance will change to that resembling Flysaac - another character from Devil's Harvest.
