Status Effects

Status Effects are special effects that can be inflicted on an enemy from a variety of sources, such as tears, bombs, and items. Each status effect has a color and symbol/effect associated with them for easy identification. These colorations are not to be confused with champions.

This page is about status effects added by Fiend Folio. More information about the vanilla status effects can be found in the vanilla page

Effects

Effect	Appearance	Description
Bruised		Bruised enemies will take 1 additional flat damage from all damage sources. Bruised can be stacked multiple times on the same enemy up to 5 times, further increasing the damage they take. The amount of extra damage an enemy takes while Bruised varies with the source that has applied it.
Drowsy and Sleepy		Drowsy enemies will turn blue and begin to slow down until they come to a complete stop and become Sleepy. Sleepy enemies will not be able to move or attack until the effect wears off. They will take double damage on the next hit they take, but this will also awaken them, ending the effect prematurely. Note: Damage an enemy takes while in the Drowsy stage of the effect won't interrupt them falling asleep.
Berserked		Berserked enemies will gain a movement and attack speed boost, and will target enemies and Isaac at random. They deal 2.1× their max HP in damage to other enemies on contact and with any projectiles they shoot, but will also deal a full heart of damage to Isaac, regardless of its original source. If there are no other enemies, they will target Isaac instead. Berserked enemies will take 50% more damage from all sources, but will also be unable to die until the effect ends, or until there are no other enemies not afflicted with Berserk.
Sewn		Sewn enemies will link together with other Sewn enemies with a thread, causing all damage they take to be applied to all other enemies linked.
Doomed		Doomed enemies will have a number counter above them. This counter will tick down by 1 each time the enemy is damaged by Isaac and, upon hitting 0, will deal a burst of 5× Isaac's tear damage and remove the Doomed effect.
Hemorrhaging		Hemorrhaging enemies will bleed profusely, taking damage every 2 game ticks, as well as creating puddles of bloody creep and spraying bloody projectiles that deal damage to other enemies. The size of the creep puddles created will scale with the size of the enemy, and the damage of the bloody creep and projectiles will fluctuate slightly, but is influenced by Isaac's damage stat and can potentially vary based on the source that applied it.
Multi-euclidian		Multi-euclidian enemies will cause any of Isaac's tears, lasers, or bombs that make contact with them to pass through and split into two parallel ones, similar to Multidimensional Baby. Note: Once a tear has been doubled, it cannot be doubled again by hitting another Multi-euclidian affected enemy.
Glitched		Glitched enemies will have their attack patterns become broken or disrupted as their AI becomes occasionally overwritten by Poople, causing them to take drastically increased knock-back and slide around the room, all while occasionally leaving brown slippery creep on the ground behind them.
Martyr		Enemies killed by items that inflict Martyr will become ghostly afterimages on death with a small aura. Standing in the aura grants a 1.1× damage multiplier, 0.8× max tear delay multiplier, and homing tears, similar to Hallowed Ground. Martyrized enemies will fade away after 5 seconds. Note: Bosses and Mini-Bosses can not become a Martyr.
