Special Traits

  • Electromagnetic Field. The electrified nature of the blue bulette is such that compasses will spin wildly within half of a mile of the bulette, and any technology-based items will cease to function within 150 feet of it.
  • Motherlode. If killed, the body of a blue bulette explodes in a loud roar of thunder (deafening all within 150 feet for 1 minute). Afterward, all that remains of the beast is a 100-pound pile of meteoric iron, which if broken, will also contain its single white horn and 1-6 small lodestones.
  • Planar Connection. Because their arcane natures tie blue bulettes to the Demi-plane of Lightning, they also simultaneously exist there as nearly invisible silhouettes intermittently illuminated by flashes of electric light.


  • Bite. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 33 (5d10 + 6) piercing damage plus 26 (4d12) lightning damage. If the target is a creature, it must succeed on a DC 15 Constitution saving throw or be knocked unconscious for 1 minute.
  • Electric Stomp. The bulette slams its forefeet into the ground, imparting a ground-conductive electric charge in an 80-foot radius. All creatures, excluding constructs and undead, must succeed on a DC 17 Constitution saving throw, or take 26 (4d12) lightning damage and be stunned for 1 minute. A stunned creature can repeat the saving throw at the end of each of its turns, ending the effect on a success.
  • Bolt and Run. The blue bulette transforms into a sphere of ball lightning and magically teleports up to 120 feet to an unoccupied space it can see.


The blue bulette is remarkable for its cerulean armor plates, frilled head carapace, and single short horn. Unlike their more subterrestrial cousins, blue bulettes are herbivores and spend their lives entirely above ground.

Aggressive when disturbed, it will defend its territory (everything in sight) against any perceived threat.
