A mihstu can pass through small holes, even cracks, without reducing its speed.
A mihstu that pins an opponent completely surrounds that creature and deals 1d2 Constitution damage every round as it siphons away blood, tears, and other vital fluids. Maintaining a pin is a free action for a mihstu and it does not gain the grappled condition (allowing it to attack other creatures with its tentacles).
The churning winds of a mihstu’s body automatically deflect nonmagical projectiles (such as arrows, bolts, and sling stones). All other ranged weapons (including magical projectiles and thrown weapons) have a 20% miss chance. Weapons of significant size, such as giant-thrown boulders, siege engine projectiles, and other massive ranged weapons are not affected by this ability.
