Multiattack. The avatar makes three attacks with its longsword or six attacks with its ignite. It can use ignite twice in place of a longsword attack.

Longsword. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 12 (2d8 + 3) slashing damage, or 14 (2d10 + 3) if wielded with two hands.

Ignite. Ranged Spell Attack: +5 to hit, range 30 ft., one target. Hit: 7 (2d6) fire damage, and the target must succeed on a DC 14 Dexterity saving throw or start burning.    A burning target sheds bright light in a 10-foot radius and dim light for an additional 10 feet. At the end of each of its turns, the target repeats the saving throw. It takes 7 (2d6) fire damage on a failed save, and the burning ends on a successful one. These magical flames can't be extinguished through nonmagical means.

Igniting Rebuke. When a creature within 30 feet of the avatar hits it with an attack, the avatar can make one ignite attack against that creature.
