Improved grab (Ex): Mhistu may attempt to grab a foe with their tentacles instead of using their sharp tips to lash. This requires a grapple check, but inflicts no damage. A grabbed foe may be enveloped during the next round.

Envelop (Ex): Incapacitated or grappled foes may be enveloped by a mhistu. Enveloped victims automatically lose one point of temporary Constitution per round.

Missile immunities (Ex): Mhistu are immune to all forms of direct missile attacks, including magical ones such as lightning bolt, magic missile, etc.

Cold susceptibility (Ex): Mhistu are susceptible to cold-based spells. Any such spell will stun them for 2d6 rounds.

To attack, mhistu form tentacle-like appendages from their bodies. They can use four such appendages at a single time. The tentacles are tipped with vicious, talon-like claws.

Air Subtype

This subtype usually is used for elementals and outsiders with a connection to the Elemental Plane Air. Air creatures always have fly speeds and usually have perfect maneuverability (see the section on Movement).
