Vulture

Vultures are large, winged predators, and one of the most persistent threats in Rain World. They move through the air using wings and gas propelled from their bodies, and catch their prey with a lunging bite before flying off back into the sky. Their chief disadvantage is their large size: Vultures are not encountered in areas inaccessible from the sky and are unable to traverse pipes or tunnels. Vultures are notable for their fearsome masks, which can be taken from them by skilled Slugcats.

Vultures are menacing foes which can appear in the majority of the game's regions. They will remain a threat throughout Industrial Complex, Garbage Wastes, Shoreline, Chimney Canopy, Sky Islands, and Farm Arrays.

Appearance
Vultures are massive aerial creatures that have a fat round body, a long slender neck, and two long wings. These wings can either be used to gain height or walk along terrain. Vultures attain buoyancy in the air by releasing or adding gas from their bodies. The gas they release is an odd pinkish-red color, and dissipates into air after being released, not retaining its color. Their head rests atop their long, skinny neck and has two large mandibles (called 'tusks' in the game files) which they use to latch onto prey. All vultures wear masks apparently made of bone, with two eye holes through which their menacing eyes can be seen glowing.

Behavior
A Vulture's arrival is typically signaled by its shadow descending over the landscape. By the time the Vulture appears on screen, it will have already seen nearby prey, and may immediately be ready to attack Slugcat. Vultures will hover above their prey briefly and make a light rustling sound before lunging headfirst to bite. If the bite connects, the Vulture will attempt to fly off with its prey. Moving quickly may help delay or prevent lunges. Lunges are interrupted by spear or rock hits, so carrying objects is useful as a last resort.

The primary weak point of all vultures is their head. Head and neck hits cause double damage, while wing hits only cause 1/10th base damage. On the first solid hit to the head, the vulture's mask will fall off. This mask can be used to scare away most lizards for a limited amount of time (17.5 seconds for regular vulture masks, 30 seconds for king vulture masks. Masked vulture bites are never lethal, but demasked vulture bites will kill 100% of the time. Vultures will attempt to fly away once hit with at least two spears.

When demasked, vultures become very aggressive, actively hunting the player down across cycles and attempting to bite the player. Maskless Vultures are also attacked by other vultures with masks, suggesting some sort of status lost when demasked.

Vultures are capable hunters and will take most small creatures and lizards, with the exception of green lizards. Hiding in a tunnel or a pipe until a Vulture leaves or catches something else is a viable option. Most other creatures will run for cover as soon as they spot a Vulture.

Hardmode (King Vultures)
King Vultures are a variant which only appear natively in hardmode. These Vultures have two sharp harpoons mounted on their masks, as well as two laser sights that move with their heads. King Vulture launch these harpoons at prey in an attempt to reel them in to be eaten.

Harpoons kill upon contact and are very accurate, so finding cover is recommended. The laser sights flash rapidly with a pulse sound three times before firing. Once both harpoons have been fired, King Vultures will typically move into close range and attempt to bite their target like normal Vultures. It takes a few seconds for the vulture to pull its harpoons out of terrain and reel them back in. King Vultures will also hunt green lizards, as well as attack each other if two are present.

Although typically only encountered in hardmode, king vultures can be made to spawn while playing as The Survivor through the lineage system by killing vultures in certain areas repeatedly.

Trivia

 * The grey caps seen on their back will open as they release gas.
 * Vultures cannot retrieve their mask, once one has been angered by taking its mask there is no way to cease its pursuit other than waiting for it to die.
 * Although Vultures are high level predators, they can be killed by several threats. Pole plants, monster kelp, scavengers, leviathans, and even green lizards can be seen killing them. Leviathans can even swallow them whole.
 * Vultures can squeeze into small pipes, although it's entirely unknown if this is a glitch or not. However, they cannot enter inter-room tunnels.
 * Vulture grubs will call on vultures when threatened. This, coupled with the vulture's strange appearance, may be sufficient evidence to determine that vulture grubs are actually baby vultures. However, there is no official confirmation or total proof of this.
 * Vultures are the third largest creature in Rain World, the second being Daddy Long Legs and the first being Leviathan.
