A creature with greater darkvision can see perfectly well in areas of darkness and dim light, though such vision is in black and white only. A creature with greater darkvision can see through even forms of magical darkness.

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.

A constant spell affects the monster without the monster needing to cast it, and its duration is unlimited. If a constant spell gets counteracted, the monster can reactivate it by spending the normal spellcasting actions the spell requires.

The augnagar's writhing limbs and flesh seethe and squirm in a disorienting and unsettling manner. Creatures in a 30-foot emanation must attempt a DC 30 will save, after which they are temporarily immune to further Confusing Displays for 1 minute. Critical Success The creature is unaffected. Success The creature is Stupefied 1 for 1 round. Failure The creature is Stupefied 1 and Confused for 1 minute. Critical Failure As failure, but the creature can't attempt a flat check to recover from confusion whenever it takes damage from an attack or spell.

Frequency once per day Effect The augnagar inhales sharply, drawing life force out of creatures in a 50-foot cone. Creatures in the area take 11d6 void damage (DC 30 fortitude save, and the creature is fatigued on a failure). The augnagar becomes Quickened for 1 round on its next turn, and it can use the extra action only to Stride or Strike.

Saving Throw DC 30 fortitude Stage 1 Drained 1 (1 day) Stage 2 Drained 2 and the creature displays hideous, festering wounds exuding a horrific stench. Any creature within 30 feet of the victim must succeed at a DC 30 fortitude save or become Sickened 1 (plus Slowed 1 on a critical failure, for as long as it's sickened). While within the aura, affected creatures take a -2 circumstance penalty to saves against disease and to recover from the sickened condition. A creature that succeeds at its save is temporarily immune for 1 minute. The victim of the disease doesn't roll a save, but takes the failure effects automatically and can't reduce its sickened value below 1 (1 day).
