Controlled Fall. When the draconian falls and isn't incapacitated, it subtracts up to 100 feet from the fall when calculating the fall's damage.
Death Throes. When the draconian is reduced to 0 hit points, its body turns to stone and releases a petrifying gas. Each creature within 5 feet of the draconian must succeed on a DC 11 Constitution saving throw or be restrained as it begins to turn to stone. The restrained creature must repeat the saving throw at the end of its next turn. On a success, the effect ends; otherwise the creature is petrified for 1 minute. After 1 minute, the body of the draconian crumbles to dust.
