Voidworm

Entropy Sense (Imprecise) 30 feet (divine, prediction) A voidworm can anticipate the most likely presence of a creature through a supernatural insight into chaotic probabilities and chance. This grants them the ability to sense creatures within the listed range. Veil of Privacy prevents a creature from being detected via entropy sense automatically (without a counteract check).

Constant Spells

Fast Healing 1

Protean Anatomy 5 (divine) A voidworm's vital organs shift and change shape and position constantly. Immediately after the voidworm takes acid, electricity, or sonic damage, they gains the listed amount of resistance to that damage type. This lasts for 1 hour or until the next time the voidworm takes damage of one of the other types (in which case its resistance changes to match that type), whichever comes first.

The voidworm is immune to polymorph effects unless it is a willing target. If Blinded or Deafened, the voidworm automatically recovers at the end of its next turn as new sensory organs grow to replace the compromised ones.

Effect: Protean Anatomy

Melee ◆ jaws +9 (finesse, magical, reach 0 feet, unarmed), Damage 1d8+1 piercing

Melee ◆ tail +9 (finesse, magical, reach 0 feet), Damage 1d4 + 1 slashing plus Confounding Lash

Divine Innate Spells DC 16, attack +8; 4th read omens; 2nd blur (self only), mist; Cantrips (1st) figment, light, prestidigitation; Constant (4th) unfettered movement

Change Shape ◆ (concentrate, divine, polymorph) The voidworm takes on the appearance of a Tiny animal. This doesn't change their Speed or their attack and damage bonuses with their Strikes but might change the damage type their Strikes deal.

Confounding Lash (divine, emotion, mental) A creature hit by the voidworm's tail Strike is Stupefied 1 for 1 round (Stupefied 2 on a critical hit). A successful DC 16 Will save negates this effect and grants temporary immunity to confounding lash for 1 minute.
