Special Traits

  • Emerald Dust. If killed (whether in solid or gaseous form), the body of a green bulette appears to implode out of existence with a thump and inward rush of air. If the immediate area is searched, it is found to be lightly dusted in a fine green powder of emerald dust, which can be collected and used to create both potent poisons and poison-based magics.
  • Gaseous Form. While in gaseous form, the bulette can occupy another creature’s space and vice versa. In addition, if air can pass through a space, the bulette can pass through it without squeezing.
  • Gone With the Wind. If a green bulette is reduced to 50% of its hit points, it disperses itself to the winds and escapes, regathering itself at a later time to rest and heal.
  • Magic Resistance. The bulette has advantage on saving throws against spells and other magical effects.
  • Planar Connection. Because their arcane natures tie green bulettes to the Elemental Plane of Air, they also simultaneously exist there as insubstantial and barely visible vaporous apparitions.

Actions

  • Bite. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 24 (3d12 + 5) piercing damage.
  • Creeping Death. While it is in gaseous form, one creature in the bulette’s space (10 ft. square) must make a DC 17 Constitution saving throw, taking 35 (10d6) poison damage on a failed save, or half as much damage on a successful one.
  • State Change. As an action, the bulette can transform from its solid form into a cloud of poisonous gas that is 10 feet square.

Reactions

  • Multi-State Existence. As a reaction after suffering at least 1 hp of damage, the green bulette shifts into it’s gaseous form, appearing as a roiling cloud of green-tinged smoke with glittering emerald particles floating within it. The green bulette remains in its gaseous form as long as threats are present and move on opponents in this form to attack, attempting to poison its adversaries. It will only revert to its solid state again once it is safe and free from attack.

About

The green bulette placidly wanders forested and mountainous areas, seeking prey. While it has the ability to kill smaller creatures with a mere bite, it prefers to stalk the largest animals it can locate. Any damaging attack upon a green bulette will trigger the reflexive shift to its gaseous state, and when hunting, a green bulette will actively seek to provoke just such attacks.
