Multiattack

The wanyudo makes two bite attacks.

Bite

Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 10 (1d10 + 5) piercing damage plus 7 (2d6) fire damage.

The wanyudo exhales fire in a 20-foot cone from one of its heads. Each creature in the area must make a DC 15 Dexterity saving throw, taking 24 (7d6) fire damage on a failed save, or half as much damage on a successful one.
