  • Immutable Form. The bulette is immune to any spell or effect that would alter its form.
  • Standing Leap. The bulette’s long jump is up to 20 feet and its high jump is up to 10 feet, with or without a running start.


  • Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 15 (2d10 + 4) piercing damage.
  • Deadly Leap. If the bulette jumps at least 15 feet as part of its movement, it can then use this action to land on its feet in a space that contains one or more other creatures. Each of those creatures must succeed on a DC 14 Strength or Dexterity saving throw (target’s choice) or be knocked prone and take 7 (1d6 + 4) bludgeoning damage. On a successful save, the creature takes only half the damage, isn’t knocked prone, and is pushed 5 feet out of the bulette’s space into an unoccupied space of the creature’s choice. If no unoccupied space is within range, the creature instead falls prone in the bulette’s space.


  • Runic Magic. The bulette activates the runes engraved on it to gain one of the following benefits until it uses this action again:
    • The bulette gains resistance to one type of damage.
    • The bulette gains a +2 bonus to AC.
    • The bulette’s attacks deal an additional 3 (1d6) force damage on a hit. A creature mounted on the bulette also gains this benefit.
  • Sheltered Cavity. The bulette opens a cavity on its back, allowing a willing creature mounted on it to become completely sheltered in its armored carapace until the bulette releases it as a bonus action. While sheltered this way, the creature is blinded and restrained, and has total cover against attacks and other effects outside the bulette. The cavity holds 10 minutes of air and a creature within it moves with the bulette. If the bulette dies or is incapacitated, any creature within the cavity is no longer restrained and can escape from the bulette’s carapace by using 5 feet of movement, exiting prone.


  • Invigorating Jolt. When a creature mounted on the bulette fails a saving throw against being charmed, frightened, incapacitated, paralyzed, or stunned, the bulette gives it an electric shock. The creature takes 4 (1d8) lightning damage and can immediately reroll its saving throw against the effect.


A runewrought bulette is a made from the hard carapace of a bulette carved with magical runes and reinforced with steel. Its bite makes it a vicious enemy but its most useful feature is its runic magic, which it can use to strengthen both itself and its rider.

One of the runewrought bulette’s most novel abilities includes securing its rider within an armored cavity on its back. Thus protected, mount and rider can burrow through the ground at great speed.
