Darkvision
A monster with darkvision can see perfectly well in areas of darkness and dim light, though such vision is in black and white only. Some forms of magical darkness, such as a 4th-level Darkness spell, block normal darkvision. A monster with Greater Darkvision, however, can see through even these forms of magical darkness.
Telepathy 100 feet (aura, divination, magical)A monster with telepathy can communicate mentally with any creatures within the listed radius, as long as they share a language. This doesn't give any special access to their thoughts, and communicates no more information than normal speech would.
Thoughtsense (Imprecise) 60 feet (divination, mental, occult)Thoughtsense allows a monster to sense all non-mindless creatures at the listed range.
At-Will SpellsThe monster can cast its at-will spells any number of times without using up spell slots.
All-Around VisionThis monster can see in all directions simultaneously, and therefore can't be flanked.
Mind SwapWhen a yithian successfully casts Possession, they exchange their mind and soul with the target. Each creature takes control of the other's body. This effect lasts until the yithian Dismisses the spell or they're forced out by any effect that ends Possession. When the effect ends, each creature's mind and soul returns to its own body, regardless of physical or temporal distance, and the yithian can cast Modify Memory on the target to remove any or all knowledge of its time being possessed. If the yithian is forced out of the target's mind by an effect, the yithian can't remove such knowledge.

Yithians are strange creatures, defined not by their physical bodies but by their ancient, disembodied minds. As a people, yithians devote themselves to the acquisition of knowledge above all else. They project their minds across the cosmos and take over a creature's body, living within and observing the creature's culture. The yithians then reverse the process and return to their communities, recording all they learned in massive tomes crafted of strange, metal alloys.
Yithians erase their hosts' memories of time spent in their bodies; however, these hosts occasionally recall odd images, usually during dreams. These recollections often involve a vast city from which great black towers rise, filling the viewer with dread. Few hosts realize these vague memories harken to their time spent in the yithian's body, when they wandered that alien city.
Four flexible and retractable appendages radiate from the top of a yithian's cone-shaped body, two of which end in sharp pincers, which they click and move to communicate, while the third ends in a cluster of funnel-shaped sensory organs. A spherical "head" rounded by three evenly-spaced eyes tops the fourth appendage. Tentacles dangling beneath this head allow for fine manipulation that the large pincers can't manage, while the crown of tentacles rising from the top like strange flowers function as ears.
Traits
This rarity indicates that a rules element is very difficult to find in the game world. A rare feat, spell, item or the like is available to players only if the GM decides to include it in the game, typically through discovery during play. Creatures with this trait are rare. They typically can't be summoned. The DC of Recall Knowledge checks related to these creatures is increased by 5.
