Vilderavn

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 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.

30 feet. DC 35 will As Frightful Presence, plus a creature frightened by the aura becomes suspicious; it doesn't count any other creature as its ally and can't Aid or flank. On a critical failure, the creature also can't be a willing target for harmless or helpful magic. Effect: Aura of Disquietude A creature that first enters the area must attempt a Will save. Regardless of the result of the saving throw, the creature is temporarily immune to this monster's Frightful Presence for 1 minute. Critical Success The creature is unaffected by the presence. Success The creature is Frightened 1. Failure The creature is Frightened 2. Critical Failure The creature is Frightened 4.

Trigger A creature within the monster's reach uses a manipulate action or a move action, makes a ranged attack, or leaves a square during a move action it's using. Effect The monster attempts a melee Strike against the triggering creature. If the attack is a critical hit and the trigger was a manipulate action, the monster disrupts that action. This Strike doesn't count toward the monster's multiple attack penalty, and its multiple attack penalty doesn't apply to this Strike.

A creature hit by a vilderavn's melee attack becomes cursed. It takes 2d6 persistent bleed damage that's difficult to stanch. The DC to stop the bleeding using Administer First Aid is 35, and healing the creature to full HP doesn't automatically end the bleeding. Removing the curse ends the bleeding.

The vilderavn takes on the appearance of a Small or Medium humanoid, wolf, dire wolf, or hybrid with both raven and wolf parts. The vilderavn can only use their jaws attack when in a form with a wolf's head, and their talon attack in a form with raven qualities. They can instead assume their raven knight form: a Medium humanoid in black full plate carrying a greatsword. They can use their jaws or talon Strikes only in a form that has that body part, and their greatsword only in knight form. The monster changes its shape indefinitely. It can use this action again to return to its natural shape or adopt a new shape. Unless otherwise noted, a monster cannot use Change Shape to appear as a specific individual. Using Change Shape counts as creating a disguise for the Impersonate use of Deception. The monster's transformation automatically defeats Perception DCs to determine whether the creature is a member of the ancestry or creature type into which it transformed, and it gains a +4 status bonus to its Deception DC to prevent others from seeing through its disguise. Change Shape abilities specify what shapes the monster can adopt. The monster doesn't gain any special abilities of the new shape, only its physical form. For example, in each shape, it replaces its normal Speeds and Strikes, and might potentially change its senses or size. Any changes are listed in its stat block.

If the vilderavn kills a humanoid with a critical hit using their jaws Strike, they rip out and devour the target's heart and soul as part of the attack. While the target is dead, the vilderavn can Change Shape into the target's form, gaining a +4 status bonus to Deception checks to impersonate the target. If magic would resurrect the creature, the caster must succeed at a DC 34 counteract check to extract the target's soul from the vilderavn; otherwise, the spell fails.
