Innate Spellcasting. The Hybrid's spellcasting ability is Intelligence (spell save DC 16). The Hybrid can innately cast the following spells, requiring no material components:
At will: fog cloud, detect magic, dispel magic, animate dead, control weather
1/day each: wall of fire, wind wall, heat metal, cure wounds (level 3), silence, insect plague, giant insect, call lightning
2/day: earthquake, hallucinatory terrain
Fire Aura. At the start of each of the Hybrid's turns, each creature within 5 feet of it takes (2d6) fire damage, and flammable objects in the aura that aren't being worn or carried ignite. A creature that touches the Demon or hits it with a melee attack while within 5 feet of it takes (2d6) fire damage.
Multiattack. The Hybrid makes four attacks: two with its longsword, one with its tail and casts one spell.
Longsword. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: (3d8) slashing damage.
Tail. Melee Weapon Attack: +9 to hit, reach 10 ft., one creature. Hit: 15 (1d10 + 2) bludgeoning damage. If the target is Medium or smaller, it is grappled (escape DC 13). Until this grapple ends, the target is restrained, the Hybrid can automatically hit the target with its tail, and the Demon can't make tail attacks against other targets.
Stunning Screech (1/Day). The Hybrid emits a horrific screech. Each creature within 20 feet of it that can hear it and that isn't an angel must succeed on a DC 14 Constitution saving throw or be stunned until the end of the Hybrid's next turn.
Parry. The Hybrid adds 5 to its AC against one melee attack that would hit it. To do so, the Demon must see the attacker and be wielding a melee weapon.
