Brass Dragon Wyrmling

Pounce. If the dragon moves at least 15 feet straight toward a creature and then hits it with a Claw attack on the same turn, that target must succeed on a DC 12 STR save or be knocked prone. If the target is prone, the dragon can make one Claw attack against it as a bonus action.

Multiattack. The dragon makes one Bite attack and one Claw attack.

Bite. _Melee Weapon Attack:_ +4 to hit, reach 5 ft., one target. _Hit:_ 7 (1d10+2) piercing damage.

Claw. _Melee Weapon Attack:_ +4 to hit, reach 5 ft., one target. _Hit:_ 5 (1d6+2) slashing damage.

Fire Breath (Recharge 5-6). The dragon exhales fire in a 30-foot line that is 5 feet wide. Each creature in that line must make a DC 11 DEX save, taking 14 (4d6) fire damage on a failed save, or half as much damage on a successful one.

Sleep Breath (Recharge 6). The dragon exhales sleep gas in a 15-foot cone. Each creature in that area must succeed on a DC 11 CON save or fall unconscious for 1 minute. This effect ends for a creature if the creature takes damage or another creature uses an action to wake it.
