Vacuum Attack (Ex)

Three times per day as a standard action, a veldenar can suddenly open and expand its jaws, drawing anything within a 15-foot cone toward its mouth. Creatures caught in this area that are Large or smaller must succeed at a DC 18 Reflex saving throw or be pulled into the veldenarâs space, potentially provoking attacks of opportunity. Attacks of opportunity caused by this ability cannot be avoided with Acrobatics (though other attacks of opportunity, such as moving out of the veldenarâs square, can be avoided as normal). The saving throw is Dexterity-based.

Viscous Air (Su)

Once per day as a free action, a veldenar can cause a 15-foot-radius sphere of air centered on its mouth to become incredibly dense. Gaseous creatures in this area must succeed at a DC 16 Fortitude saving throw or be affected as if by a slow spell (CL 10th).

Other corporeal creatures treat the area as difficult terrain.

Unless consumed during the creatureâs vacuum attack (in which case the viscous air immediately dissipates), the viscous air remains for 10 rounds before dissipating.

Veldenars are unaffected by the viscous air. Creatures can notice the region of altered air from a distance of up to 20 feet with a successful DC 20 Perception check.

Environment any (Plane of Air)
Organization solitary or pair

Veldenars are ambush predators native to the Plane of Air. They have pale, almost clear, skin, four stubby leg-like appendages, a tail like that of a fish, and six black-and-red eyes on their heads. Veldenars are naturally buoyant in air. They typically feed on gaseous creaturesâespecially belkers and mihstusâthough veldenars attack most anything that gets too close.

Veldenars hide invisibly in areas that are abundant with prey. When a meal gets close enough, the veldenar unleashes its cloud of viscous air, then opens its mouth.

The sudden change in pressure draws the prey into its gullet to be digested. While veldenars are more than capable of eating humanoid creaturesâand often do when such beings enter their hunting groundsâthey favor gigantic insects and beings of elemental fire.

A typical veldenar is around 17 feet long and weighs about 3,000 pounds.
