Air Dragon Hatchling

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) piercing damage plus 3 (1d6) lightning damage.

Breath Weapons (Recharge 5–6). The dragon uses one of the following breath weapons. 

Lightning Breath. The dragon exhales lightning in a 15-­foot line that is 5 feet wide. Each creature in that line must make a DC 13 Dexterity saving throw, taking 18 (3d10) lightning damage on a failed save, or half as much damage on a successful one.

Paralyzing Breath. The dragon exhales paralyzing gas in a 15-foot cone. Each creature in that area must succeed on a DC 13 Constitution saving throw or be paralyzed for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Storm Cloud. The dragon creates a storm cloud that is 15 ft. wide, 5 ft. thick that provides 1/2 cover to any ally behind the wall within 30 ft of it. The storm cloud can be moved up to 60 ft. as a bonus action. It lasts for up to a minute or until concentration is broken. If an enemy comes in contact with the cloud it must succeed on a DC 13 Strength saving throw or be knocked prone.

Shield. The dragon can shield its marked ally once per short rest as long as they are within 60 ft of each other.
