Multiattack

The devil makes two attacks with its claws and one with its tail. Alternatively it uses Hurl Flame twice.

Claws

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) piercing damage. If both claw attacks hit the same Medium or smaller creature it is grappled (escape DC 15). While the target is grappled this attack may be used only against the grappled creature and has advantage against that creature.

Tail

Melee Weapon Attack: +7 to hit, reach 5 ft., one target the devil is not grappling. Hit: 10 (2d6 + 3) piercing damage.

Hurl Flame

Ranged Spell Attack: +6 to hit, range 150 ft., one target. Hit: 10 (3d6) fire damage. If the target is a creature it catches on fire taking 5 (1d10) ongoing fire damage. If the target is an unattended flammable object it catches on fire. A creature can use an action to extinguish this fire.
