Cave Dragon Wyrmling 2014
CR 2 dragon
Medium dragon, Neutral Evil
The cave dragon naturally suppresses light near it. Bright light within 15 feet of the dragon becomes dim light, and dim light within 15 feet becomes nonmagical darkness.
The cave dragon can burrow through nonmagical unworked earth and stone. While doing so, the dragon can choose whether to leave the material it moves through undisturbed or leave a 5-foot diameter tunnel in its wake.
Actions
Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 9 (1d10 + 4) piercing damage plus 3 (1d6) poison damage.
The dragon exhales a cone of black, poisonous gas in a 15-foot cone. Each creature in that area must make a DC 13 Constitution saving throw. On a failure, a creature takes 14 (4d6) poison damage and is poisoned until the end of its next turn. On a success, a creature takes half the damage and isn't poisoned.
