Keen Sight and Smell. The owlbear has advantage on Wisdom (Perception) checks that rely on sight or smell.

Multiattack. The owlbear makes two attacks: one with its beak and one with its claws.

Beak. Melee Weapon Attack: +7 to hit, reach 5 ft., one creature. Hit: 10 (1d10 + 5) piercing damage.

Claws. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 14 (3d10 + 5) slashing damage.

Fire Spit. Ranged Spell Attack: +10 to hit, reach 30 ft., one target. Hit: 19 (2d12 + 6) Fire damage. If the target is a creature or a flammable object, it ignites. Until a creature takes an action to douse the fire, the target takes 5 (1d10) fire damage at the start of each of its turns.

Chilling Stare. Ranged Spell Attack: +10 to hit, reach 30 ft., one target. Hit: 13 (1d12 + 6) cold damage plus 13 (1d12 + 6) psychic damage, and the target must succeed on a DC 15 Wisdom saving throw or become frightened for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Shocking Slam. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 14 (2d8 + 5) bludgeoning damage plus 9 (2d8) lightning damage, and the target must succeed on a DC 18 Strength saving throw or be knocked prone.

Air Slice. Ranged Spell Attack: +10 to hit, reach 60 ft., one target. Hit: 24 (3d10 + 7) force damage.

Twister (Recharge 5–6). The owlbear whips up a tornado that travels in a 90 foot line. Each creature in that area must make a DC 20 Strength saving throw, taking 60 (12d8) bludgeoning damage on a failed save, or half as much damage on a successful one.
