Boils are spherical monsters encountered in The Caves/The Catacombs and The Depths/Necropolis.
Its bipedal variant (Walking Boil) was introduced in the Wrath of the Lamb DLC, where it can be encountered in The Catacombs, Necropolis, and both levels of Chapter 4 (The Womb and Utero).
Behavior[]
They start off as a small red sphere and slowly grow to full size. When at their full size, they can spurt out short-ranged blood shots at Isaac, similar to one of Monstro's attacks. Boils decrease in size when hit, but will regenerate to their full size until fully destroyed.
Boils are nearly harmless on their own, as they can simply be killed from a distance and do not deal damage on contact. With other enemies, however, they are far more dangerous: If Isaac enters a room with a large crowd of enemies and several Boils providing covering fire, taking out enough of the Boils to give himself breathing room should be a big priority.
Champion Variant[]
Eternal Boils fire significantly more blood shots. They are some of the easiest eternal enemies, as they still do not attack when they are not at full size.
This variant was added in the Eternal Edition update but can be exclusively encountered in Hard Mode.
