Zombie Owlbear

CREATURE 3
LARGEEVILMINDLESSUNDEADUNHOLYZOMBIE

Zombie owlbears combine an owlbear's ferocity with mindless undead hatred. Once it draws near, it often stands up, unleashing a guttural, wet roar, before charging into combat without thought of self-preservation.

Simple to create and varied in purpose, these shambling undead are often used for their strength and endless stamina to conduct boring, repetitive tasks.

Slow

A zombie owlbear is permanently Slowed 1 and can't use reactions.

Void Healing

A creature with void healing draws health from void energy rather than vitality energy. It is damaged by vitality damage and is not healed by vitality healing effects. It does not take void damage, and it is healed by void effects that heal undead.

Speed 25 feet
Melee Talon +12 (unarmed), Damage 1d10+7 piercing plus Grab
Melee Beak +12 (unarmed), Damage 1d12+7 piercing
Ground Slam (attack)
Requirements The zombie owlbear has a creature Grabbed or Restrained with its talons
Effect The zombie owlbear repeatedly slams the creature into the ground. This deals 1d10+7 bludgeoning damage (DC 20 basic Fortitude). On a critical failure, the creature is Stunned 1, and on a critical success the creature is no longer grabbed or restrained.
Horrifying Screech (auditory, emotion, fear, mental)

The zombie owlbear unleashes a broken, snarling screech that unnerves those who hear it. Each creature in a 60-foot emanation must attempt a DC 19 Will save. Regardless of the result, creatures are temporarily immune for 1 minute.

Critical Success The creature is unaffected.

Success The creature is Frightened 1.

Failure The creature is Frightened 2.

Critical Failure The creature is Fleeing for 1 round and Frightened 3.

Grab

Requirements The monster's last action was a successful Strike that lists Grab in its damage entry, or the monster has a creature Grabbed or Restrained
Effect If used after a Strike, the monster attempts to Grapple the creature using the body part it attacked with. This attempt neither applies nor counts toward the creature's multiple attack penalty.

The monster can instead use Grab and choose one creature it's grabbing or restraining with an appendage that has Grab to automatically extend that condition to the end of the monster's next turn.
