Invisible Stalker

Outsider: An outsider is at least partially composed of the essence (but not necessarily the material) of some plane other than the Material Plane.

Outsiders have darkvision.

Unlike most living creatures, an outsider does not have a dual nature — its soul and body form one unit. When an outsider is slain, no soul is set loose. Spells that restore souls to their bodies, such as raise dead, reincarnate, and resurrection, don’t work on an outsider. A different magical effect, such as limited wish, wish, miracle, or true resurrection, is required to restore it to life. A native outsider can be raised, reincarnated, or resurrected just as other living creatures can be.

Outsiders breathe, but do not need to eat or sleep (although they can do so if they wish). Native outsiders breathe, eat, and sleep.

Air: Air creatures are usually outsiders with a connection to the Elemental Plane of Air. Air creatures always fly and usually have perfect maneuverability.

Elemental: An elemental is a being composed entirely from one of the four classical elements: air, earth, fire, or water.

They have immunity to bleed, paralysis, poison, sleep effects, and stunning.

They are not subject to critical hits or flanking. They do not take additional damage from precision-based attacks, such as sneak attack.

Elementals do not breathe, eat, or sleep.

Extraplanar: Extraplanar is any creature when it is on a plane other than its native plane. A creature that travels the planes can gain or lose this subtype as it goes from plane to plane. Creatures not extraplanar are natives of the Material Plane, and they gain the extraplanar subtype if they leave the Material Plane. No creature has the extraplanar subtype when it is on a transitive plane, such as the Astral Plane, the Ethereal Plane, or the Plane of Shadow.

Very little is known about these enigmatic and mysterious creatures, as their very nature makes details of their true form difficult to discern. Brought to this world from the Plane of Air, these creatures fulfill tasks for those who conjure them. Invisible stalkers act as guardians, assassins, and trackers, occupations in which they excel. Their natural invisibility and skill at stealth allow them to follow their quarry without detection and give them the upper hand when it comes to exterminating a mark.

Many invisible stalkers resent this and see these petty tasks as nothing more than chores dictated by mortals. When given a particularly complex or bothersome task, an invisible stalker seeks to find a loophole in a poorly worded instruction. For instance, wizards calling an invisible stalker into service with the instructions “protect me from danger” might find themselves escorted to a faraway hidden location, or even brought to the Plane of Air.

An invisible stalker takes no penalty when tracking and moving at any speed.

Due to their constant summoning, many invisible stalkers harbor hostility for those dwelling on the Material Plane. Those invisible stalkers new to the mortal world only know the stories of their kind and tend to keep an open mind about the intentions of those who call them. Over time, or in the service of a particularly vile master, invisible stalkers form negative opinions of these creatures of flesh and bone, leading to their tendency to pervert their instructions and cause harm to their masters. For older and more experienced invisible stalkers, the only thing protecting those who summon them is the magic that binds them. These creatures automatically try to use inconsistencies in the wording of their tasks and literal twists on the intention to find a way to inconvenience, injure, or even kill the priest or arcanist that brought them to the plane.

An invisible stalker remains invisible at all times, even when attacking. As this ability is inherent, it is not subject to the invisibility purge spell.
