Brass Dragon Wyrmling

Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 7 (1d10+2) slashing damage.

The dragon exhales fire in a 20-foot-long, 5-foot-wide line. Each creature in that area must make a Dexterity saving throw (DC 11), taking 14 (4d6) fire damage on a failed save, or half as much damage on a successful one. Recharge 5-6.

The dragon exhales a cloud of sleep gas in a 15-foot cone. Each creature in that area must make a Constitution saving throw (DC 11). On a failed save, the target is Incapacitated until the end of its next turn, at which point it repeats the save. If it fails this second save, it is Unconscious for 1 minute. This effect ends for the target if it takes damage or a creature within 5 feet of it takes an action to wake it. On a successful save, nothing happens.
