Special Traits

  • Spines. A creature that makes a melee attack against a stegocentipede while within 5 feet of the stegocentipede must make a successful DC 12 Dexterity saving throw or take 6 (1d8 + 2) slashing damage from spines on the stegocentipede’s carapace.


  • Multiattack. The stegocentipede bites once and stings once.
  • Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) piercing damage.
  • Sting. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 13 (2d8 + 4) piercing damage and the target must make a successful DC 12 Constitution saving throw or be poisoned. While poisoned, the creature takes 7 (2d6) poison damage at the start of its turn. A poisoned creature repeats the saving throw at the start of its turn, ending the effect on itself with a success.


Stegocentipedes resemble gigantic centipedes covered with plates of chitin with spikes that can be raised or lowered along its back and flanks. Its tail ends in a wicked, whip-like stinger.

They are arthropods that have grown to stunning size. They are rumored among sages to have come to the Material Plane from another plane or dimension, though no proof has been found to support this theory. It is based chiefly on the fact that nothing else like them exists. It’s possible that stegocentipedes were brought by the skelzis to help spread terror.

A typical stegocentipede is 18 feet long, but there is much variety among the species. A stegocentipede raises its spines instinctively when it enters combat, and it moves constantly in a back-and-forth, sawing motion as it fights.
