Actions
Multiattack.
The dragon attacks once with its bite and twice with its claws. In place of its bite attack it can use Acid Spit.
Bite.
Melee Weapon Attack: +15 to hit reach 15 ft. one target. Hit: 30 (4d10 + 8) piercing damage plus 9 (2d8) acid damage. Instead of dealing piercing damage the dragon can grapple the target (escape DC 23) and a Huge or smaller creature grappled in this way is restrained. While grappling a creature the dragon can't bite or use Acid Spit against another target.
Claw.
Melee Weapon Attack: +15 to hit reach 10 ft. one target. Hit: 21 (3d8 + 8) slashing damage.
Tail.
Melee Weapon Attack: +15 to hit reach 20 ft. one target. Hit: 21 (3d8 + 8) bludgeoning damage and the dragon pushes the target 10 feet away.
Acid Spit.
The dragon targets a creature within 60 feet forcing it to make a DC 22 Dexterity saving throw. The creature takes 22 (4d10) acid damage on a failure or half damage on a success. A creature that fails the save also takes 11 (2d10) ongoing acid damage. A creature can use an action to end the ongoing damage.
Acid Breath (Recharge 5-6).
The dragon exhales sizzling acid in a 90-foot-long 10-foot-wide line. Each creature in that area makes a DC 22 Dexterity saving throw taking 85 (19d8) acid damage on a failed save or half damage on a success. A creature that fails the save is blinded until the end of its next turn.
