Death Throes.

When the draconian is reduced to 0 hit points, its scales and flesh immediately shrivel away and its bones explode. Each creature within 10 feet of it must succeed on a DC 10 Dexterity saving throw or take 9 (2d8) force damage.

Glide.

When the draconian falls and isn't incapacitated, it subtracts up to 100 feet from the fall when calculating the fall's damage, and it can move up to 2 feet horizontally for every 1 foot it descends.
