Flying Charge.  If Henociraptor moves at least 20 feet straight towards a creature, it can make one Claws attack against them as a bonus action.

Actions

• Multiattack. Henociraptor makes two attacks, one with its beak, and one with its claws. 
• Absorbeak. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 14(4d6+3) piercing damage. After hitting the creature, Henociraptor’s beak begins glowing and absorbing vitality from the target. The target must make a DC 14 Constitution saving throw, taking (2d6) necrotic damage on a failure and having their Strength score reduced by 1 until they finish a short or long rest. Henociraptor heals for the amount equal to necrotic damage dealt, and recharges the Egg Attack action
• Claws. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit 13(4d4+3) slashing damage. 
• Egg Attack Henociraptor drops an egg on a creature directly below it within 60 feet. That creature must make a DC 14 Dexterity saving throw, taking 22 (4d10) bludgeoning damage on a failed saving throw. This attack cannot be used again, until Henociraptor successfully recharges this ability with the Absorbeak action.
