White Dragon Wyrmling

Ice Walk. The dragon can move across and climb icy surfaces without needing to make an ability check. In addition, difficult terrain composed of ice or snow doesn't cost it extra movement.

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 plus 2 (1d4) cold damage.

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

Cold Breath (Recharge 5-6). The dragon exhales an icy blast in a 15-foot cone. Each creature in that area must make a DC 12 CON save, taking 22 (5d8) cold damage on a failed save, or half as much damage on a successful one.
